What do young earth creationists think about the dinosaurs? by fdsfsdfsd Q: Most young earth creationists claim that the earth is 6,000 years old (though the wikipedia page on this subject says the earth is approximately 4.5 billion years old). The dinosaurs existed over 100 million years ago, which disproves the young earth creationist myth regarding the age of the world. What is the young earth creationist explanation for the dinosaurs?

A: I've heard young earth creationists try to explain the dinosaurs. According to carbon dating, the dinosaurs existed over 100 million years ago, which certainly disproves the creationist myth that the earth is merely 6,000 years old. Creationists point to the fact that the characters in the book of Genesis lived uncannily long lives. For instance, Adam lived 930 years. Creationists say that reptiles, who supposedly continue to grow throughout their lives, who were around in the days of Adam and Eve lived just as long as the characters in Genesis; and accordingly, the reptiles had plenty of time to grow into dinosaurs. The issue with the above theory is the fact that it ignores carbon dating, which creationists claim is flawed. However, creationists provide no plausible, scientific evidence that supports the claim that carbon dating is inaccurate.

A: They think God put dinosaur fossils on earth to test their faith. Yep, I'm not joking either. Matthew: So I suppose God gave them 100 million year old carbon skeletons did he? Ah yes! Why didn't I think of that. You know, I wasn't going to be mean about this, but I cannot believe how ignorant you guys are, you actually believe this earth was created 6000 years ago? I mean please...just PLEASE look at all the scientific evidence, carbon dating, other dating methods, fossils. But no, I guess your book must be right eh? Obviously ink on a piece of paper is more reliable than cutting edge scientific dating methods. Scientists aren't here to bash Christians you know, It's just the LOGICAL way foreward, and I'm sorry to say, but yours is just going by what's said in a book, which, for all you know, could've been an ancient fairtytale told to children before they went to sleep (And since there's no historical evidence for Jesus Christ at all, except a few documents containing the world "christos" which just means "Anointed one, may very well be a likely explanation) If Jesus went around healing the sick and walking on water, you'd think there'd be a SHREAD of evidence for him, right? Nope, nothing! Hell, maybe someone will find Harry Potter in 5000 years and start worshipping Harry as their messiah and worshipping his holy powers to unlock doors with his magic wand. Yeah.

What do young earth creationists think about the dinosaurs? by Tamil Rationalist Q: Most young earth creationists claim that the earth is 6,000 years old (though the wikipedia page on this subject says the earth is approximately 4.5 billion years old). The dinosaurs existed over 100 million years ago, which disproves the young earth creationist myth regarding the age of the world. What is the young earth creationist explanation for the dinosaurs?

A: The topic of dinosaurs in the Bible is part of a larger ongoing debate within the Christian community over the age of the earth, the proper interpretation of Genesis, and how to interpret the physical evidences we find all around us. Those who believe in an older age for the earth tend to agree that the Bible does not mention dinosaurs, because, according to their paradigm, dinosaurs died out millions of years before the first man ever walked the earth. The men who wrote the Bible could not have seen living dinosaurs. Those who believe in a younger age for the earth tend to agree that the Bible does mention dinosaurs, though it never actually uses the word “dinosaur.” Instead, it uses the Hebrew word tanniyn, which is translated a few different ways in our English Bibles. Sometimes it’s “sea monster,” and sometimes it’s “serpent.” It is most commonly translated “dragon.” The tanniyn appear to have been some sort of giant reptile. These creatures are mentioned nearly thirty times in the Old Testament and were found both on land and in the water. In addition to mentioning these giant reptiles, the Bible describes a couple of creatures in such a way that some scholars believe the writers may have been describing dinosaurs. The behemoth is said to be the mightiest of all God’s creatures, a giant whose tail is likened to a cedar tree (Job 40:15). Some scholars have tried to identify the behemoth as either an elephant or a hippopotamus. Others point out that elephants and hippopotamuses have very thin tails, nothing comparable to a cedar tree. Dinosaurs like the brachiosaurus and the diplodocus, on the other hand, had huge tails which could easily be compared to a cedar tree. Nearly every ancient civilization has some sort of art depicting giant reptilian creatures. Petroglyphs, artifacts, and even little clay figurines found in North America resemble modern depictions of dinosaurs. Rock carvings in South America depict men riding diplodocus-like creatures and, amazingly, bear the familiar images of triceratops-like, pterodactyl-like, and tyrannosaurus rex-like creatures. Roman mosaics, Mayan pottery, and Babylonian city walls all testify to man’s trans-cultural, geographically unbounded fascination with these creatures. Sober accounts like those of Marco Polo’s Il Milione mingle with fantastic tales of treasure-hoarding beasts. In addition to the substantial amount of anthropic and historical evidences for the coexistence of dinosaurs and man, there are physical evidences, like the fossilized footprints of humans and dinosaurs found together at places in North America and West-Central Asia. So, are there dinosaurs in the Bible? The matter is far from settled. It depends on how you interpret the available evidences and how you view the world around you. If the Bible is interpreted literally, a young earth interpretation will result, and the idea that dinosaurs and man coexisted can be accepted. If dinosaurs and human beings coexisted, what happened to the dinosaurs? While the Bible does not discuss the issue, dinosaurs likely died out sometime after the flood due to a combination of dramatic environmental shifts and the fact that they were relentlessly hunted to extinction by man.

What would happen if earth had no way of balancing energy through storms? by Certified Storm Spotter SKYWARN Q: We have storms and that's how the energy on earth is balanced. What would happen if there were no storms and the earth didin't have some way of balancing out energy? Sources?

A: There are three ways nature can transport energy. 1. Convection 2. Conduction 3. Radiation If none of these methods are available, then there would not be an unbalanced energy situation on Earth. The reason is that you must have a way to transport energy to different parts of the world by internal (example: heat energy from the core of the earth) and/or external sources (example: solar radiation from the sun) to start with in order to get that unbalance situation on the surface of the Earth. Now, if you are talking about eliminating convection as a way of transporting energy, which is what makes most of our weather on Earth, then the Earth will use the other two methods of radiation and conduction to try to bring things into balance. This, in my opinion, will result in a much slower and less efficient way to transport the energy from the equator to the polar region. Thus, I would think that the temperature would be much more extreme at these locations.

What do young earth creationists think about the dinosaurs? by Tamil Rationalist Q: Most young earth creationists claim that the earth is 6,000 years old (though the wikipedia page on this subject says the earth is approximately 4.5 billion years old). The dinosaurs existed over 100 million years ago, which disproves the young earth creationist myth regarding the age of the world. What is the young earth creationist explanation for the dinosaurs?

A: Young-Earth creationists do not think. They have "faith" instead.

What effect does the solar wind have on Earth’s magnetic field? by ekrjektkn Q: What effect does the solar wind have on Earth’s magnetic field? A. Compasses on Earth stop working. B. Earth’s magnetosphere is spread out farther on the side of Earth not facing the sun. C. The magnetic field on the side facing the sun is warmer. D. Solar wind causes magnetic declination.

A: B. Earth’s magnetosphere is spread out farther on the side of Earth not facing the sun.

How large is the Earth compared to other objects in the solar system? by JessiiBabii Q: Also if you know what is earth's place in the galaxy and our galaxy's place in the universe.

A: Check out this link: http://www.co-intelligence.org/newsletter/comparisons.html This shows Earth's size compared to our sun and the other planets in our solar system (with pictures) and them compares our sun to other stars. It's mind-boggling. :-)

What evidence is there to refute Young Earth theorists? by Spector Q: Proponents of Young Earth theory assert that the Earth is no older than 15,000 years. What evidence is available that refutes this theory? On what do they base this theory? Thank you for your input.

A: Geological research over the past couple of centuries happens to be at odds with the Earth being no older than 15,000 years. This reality has since been corroborated by radiometric dating which, again and again and again, demonstrates an age going back hundreds and, indeed, thousands of millions of years. <> There isn't a Young Earth theory. Theories in science are based upon and tested against the available evidence. Rather, there's a faith-based fantasy held by people, who don't like the reality that their perceived deity may have created.

What would happen if Earth and Venus switched places? What do you think would happen to Venus? by Garrett Wills Q: . If Earth and Venus somehow switched places, the Earth would experience a runaway greenhouse eect. What do you think would happen to Venus? Specically, would it become Earth-like?

A: Assuming Venus comes with the same atmosphere it had before the switch, then it would still be a lot hotter than Earth even after it had had time to settle down - this is because these gases are greenhouse gases. Also, a day on Venus is many Earth days, or months, long I'm not sure - which would mean the night side would suffer a deep freeze, only to completely thaw out during it's day. This, along with the poisonous gases, would make the evolution of life tricky I'd imagine -but 'life finds a way'.

How does earth's gravitational force differ on the surface as compared to in space? by uc0nnh00ps Q: How does Earth's gravitational force on you differ when you are standing on earth and when you are riding in a space shuttle 400 km above Earth's surface?

A: The gravitational force is almost the same. In that orbit you are 400 km further from the centre of the Earth and so the gravity field strength is reduced but only by 6400^2 / 6800^2 = 0.886 ( call it 12% ) The gravity force on you will be 12% less than if you were on the surface.

How do i re-word the sentence The core of the earth melts the earths rocky interior and produces pockets of ma? by Lauryssa Q: Re-word: The core of the earth melts the earths rocky interior and produces pockets of magma near the earths surface.

A: The Earth's core produces pockets of magma near the surface by melting the rocky interior

What is the radial acceleration of the earth toward the sun? by lilant2012 Q: The radius of the earth's orbit around the sun (assumed to be circular) is 1.50 x 10^8 km, and the earth travels around this orbit in 365 days.

A: The radial acceleration is given by m*a = m*v^2/r where m is the mass of the earth (not needed), v the velocity and r the radius. v is given by v=2*pi*r/T where T is 365 days. If you do the work, you will find that v= 30km/s (rounded off) and a = 6*10^-3 m/s^2

How is time calculated for astronauts traveling around the earth faster than the earth rotates? by JamesS Q: One revolution of the earth constitutes a 24 hour day. So, if the astronauts travel around the earth faster than the earth revolves in a 24 hour period, how is their time arrived at? And, just for fun, do they age faster?

A: With a clock :| 24-hour days is something created by men to organize and measure time. In order to have accurate measurements the astronaut's clock has to be synchronized with their station on earth.

How do we have have seasons if the earth is round? by utunr247 Q: Scientist say the Earth is round, then again they say we have seasons because it is tilted towards the sun. So the question is are the scientist lieing to each other? In order to have seasons the earth would have to be oval shaped. So if it is round, how do we have seasons?

A: ( / ) --- O --- ( / ) Earth 6-20 --- Sun --- Earth 12-21, 2008 The parentheses are to show the Earth is round; the slash is to show the axis (the tilt) of the Earth. 6-20, on the first day of summer, the northern hemisphere is tilted toward the sun (our summer), the southern hemisphere is tilted away from the sun (their winter). After six months of the earth traveling around the sun... 12-21, on the first day of winter, the northern hemisphere is tilted away from the sun (our winter), the southern hemisphere is tilted toward the sun (their summer).

What would happen if the Earth revolved around the moon and the sun revolved around Earth? by Lola Q: Would life still be possible on Earth? (I know this is impossible due to the gravitational pull, but hypothetically speaking) I know it is impossible, as I stated before. I said hypothetically speaking. thank you sunshine.

A: It would be impossible because the gravity of earth is more than that of the moon and 100000000 earths could fit in the sun so you should get it by now

How do I find the formulas for spin–orbit resonance between the earth and the moon? by Douglas G Q: The moon and earth. Earth day getting longer and Moon orbit around earth getting longer and the moon being thrown away from earth.

A: Do you want the equations for how the orbit of the moon has evolved in the past and will evolve in the future? And for the spin of the Moon and the Earth? This is a very complex subject and takes much study. You could start with the links below. But be prepared for a year or two of advanced college-level maths.

When a gopher creates an underground "tunnel" where does the earth go that was in the tunnel space? by srewsna Q: Some of the earth is usually in a mound around the gopher hole. But that amount is not nearly enough to account for the earth that was removed by the gopher when creating the long tunnel. So where is the earth that was in the tunnel? Does the gopher put it someplace else?

A: Some of compacts into the walls of the tunnel, shallow tunnels just "push up" the earth which may be hard to see in long lawns, etc, they also dig a lot of side tunnels/holes so the the dirt is distributed out to many locations. I've noticed the gophers and moles in my yard also like to take advantage of the the landscape fabric/plastic that's been laid down over the years, using it to the "top" of the tunnels so they're actually moving less dirt out of the tunnel holes, pushing the dirt to form the sides to hold up the fabric.

How is the earth's atmosphere different from the atmosphere on mars? by Amanda S Q: Earth atmosphere mainly consists of nitrogen and oxygen, mars atmosphere mainly consists of carbon dioxide, nitrogen and argon?

A: Yup, that's pretty much it.  Also, Earth has about 40 times as much atmosphere (mass) per unit of area than Mars does (Mars has about 1/100 the surface pressure because of lower gravity).

How much closer is the Earth to the Sun during winter? by ZombieSeaweed Q: I heard that the Earth is closer to the sun during Winter. How much closer is it by miles?

A: http://en.wikipedia.org/wiki/Earth Aphelion (June)152,098,232 km Perihelion (January)147,098,290 km difference ~5,000,000 km or 3.1 million miles

How can you calculate the earth vector during its motion around the sun? by lonelyspirit Q: What is the vector (speed and direction) of the earth motion around the sun? Could you kindly state the equation of the earth motion around the sun? Also, from the equation, what is the earth vector on December 21, and on January 5, every year? I would greatly appreciate your assistance in this matter. References to any site that shows the eccentricity of earth motion around the sun is also very much appreciated. Thank you!

A: In astronomy, Kepler's laws give a description of the motion of planets around the Sun. http://en.wikipedia.org/wiki/Kepler%27s_laws_of_planetary_motion Kepler used these three laws for computing the position of a planet as a function of time. His method involves the solution of a transcendental equation called Kepler's equation. http://en.wikipedia.org/wiki/Kepler%27s_equation Earth orbits the Sun at an average distance of about 150 million kilometers every 365.2564 mean solar days, or one sidereal year. http://en.wikipedia.org/wiki/Earth#Orbit

What is the best program to get live satelite images of the earth? by devlin m Q: Google earth, Virtual earth, are there any just amazing live feeds price not an equation.

A: You cannot get LIVE satellite views of the earth. The images you see on google earth or zillow.com were taken months ago. The bandwidth for satelites is expensive so they are limited to government use such as NSA. The satellite views you will see online are all from the same source so it doesn't make a difference really. I prefer google earth because of the new features such as dropping altitude and getting a horizontal view of the planet with actual building heights.

What would happen if all the fat people on earth fell over at the same time? by Anonymous Q: Would the earth's plates crack and go haywire and cause earthquakes all over the place? Or would the earth be thrown off its orbit? If all the fat people in the world gathered in one country and then fell over would that affect the orbit?

A: Lol!!!! Assuming the fat people are fairly evenly distributed, then the orbit would be unaffected. ;) And as for earthquakes... well, the plates would be fine, but there might be some minor earth quakes in areas where lots of fat people were close together.

How close would the moon have to be to Earth to enter its Roche limit? by Loosey™ Q: Will the Earth ever have rings like Saturn if the moon gets close enough? You're right for now Qualkar, but that will change over time.

A: Using the formula from the source and looking up the sizes and density of the Earth and Moon, I calculate this: About 1.4 times the radius of the Earth, or 9,496 kilometers. That is the distance between the centers of the two bodies. Subtracting the radius of the Earth and Moon, the two surfaces would be 1,381 kilometers apart. That is about 830 miles.

What would happen if all of the earth received the same amount of heat from the sun? by JE Q: What would happen to the earth, if all parts of the earth, were to receive the same amount of the sun's heat output in terms of temperature?

A: then it means the earth would be flat like a table instead of spherical. 1)ppl wouldn't travel round the world has they will get to an edge were they will fall 2)everywhere will be warm,so no place will be interesting to move since u have same climate. 3)everyone will be same colour,an would leave close to each other instead of seperate. 4)no one will work hard or develop much food or machines,because they will produce similar food. 5)if global warming occurs,the world will be easilly flooded

What would happen to earth if a massive asteroid hit the moon? by krazymaiden Q: What would happen to earth if a massive asteroid hit the moon hard enough to push it out of its present orbit?

A: Well the fact that it hasn't happened yet kind of makes me think that there isn't a big enough asteroid that could do that except maybe Ceres but Ceres is a dwarf planet now, so i would have to say that even a massive asteroid wouldn't knock the earth out of it's orbit. An asteroid the size your talking about though would end all life on earth, even those people in deep level bunkers would be killed.

What would be consequences to the climate of Earth rotating in the opposite direction ? by Martin M Q: Would the Earth still be habitable, or is the current rotation the only option to maintain life ?

A: The tidal bulge that the moon causes in the earth would rotate in the opposite direction, pulling against the moon rather than speeding it up. Consequently, the orbit of the moon would decay at the rate of about one inch per year. The earth's climate would not be affected for a long time, but eventually the moon would be close enough to earth to cause great oceanic tides. This was the case when the moon first formed. Gigantic tides swept over the earth, washing minerals and salts into the seas. At that time, the moon was only 40,000 miles away, compared to its present distance of 239,000 miles.

How fast would the earth have to travel if orbiting the sun fully in 24 hours? by owen eastwood Q: Basically just that. Assuming the earth orbited the sun fully (360 degrees) in 24 hours, how fast would it have to travel?

A: It is physically impossible for Earth to orbit the sun in 24 hours and still obey the Laws of Physics. In order for that to happen, Earth's orbit would have to be so close to the sun that it would be burned ash. However, assuming that Earth could stay in its current orbit while orbiting the sun in 24 hours, it would have to travel at a speed of 24,334,174.08 miles per hour. Earth currently travels at an average speed of 66,622.18 miles per hour. .

Does the Earth atmosphere also rotate accordingly to the same direction and speed of the Earth rotation? by Azman M Q: Does the Earth atmospere rotates the same way the Earth does? Does the Earth gravity also play its part on the Earth atmosphere? Coriolis effect?

A: The atmosphere is part of the Earth. It rotates along with the Earth due to momentum and friction. If it didn't, you would be experiencing 17 500 mile per hour winds. The atmosphere does not orbit the Earth.

How is life on earth protected from dangerous radiation emitted by the sun? by Q: The conditions on the surface of the Earth are influenced by the interaction between physical phenomena and generated both by the Sun and the Earth. Discuss these phenomena and explain how life on Earth is protected from dangerous radiation emitted by the sun.

A: Simple Answer The Ozone Layer The ozone layer is the byproduct of very short wave UV (UV-C) breaking apart oxygen molecules. When ozone is formed, it serves to block energetic UV (UV-B) that other molecules don't, and acts to moderate day / night temperature swings a little bit. Ozone absorbs UV-B, which would otherwise damage our DNA, and the DNA of all surface dwellers on Earth (including phytoplankton in the oceans). The act of absorption of UV-B or more energetic light breaks the ozone down into an oxygen molecule and a single oxygen atom. A few of these fragments reassemble as ozone. But primarily UV-C is required to break apart more oxygen to make replacement ozone. The ozone layer is like a blanket that shields Earth (not just the living things). It is a "greenhouse gas" that moderates day / night temperature swings, and allows the "heat" of the nitrogen and oxygen at altitude to be radiated away (both up and down).

How does Earth's atmosphere compare with the atmospheres of Venus and Jupiter? by JayJ Q: Earth Science homework question that i am stuck on. Any help would be greatly appreciated. Thank you!

A: Earth atmosphere is way thinner than the atmospheres of Venus and Jupiter. The atmosphere of Venus is so thick it creates astounding 90bar air pressure at the surface and because it's all made of carbon dioxide it acts like a blanket creating temperatures up the 500C. Jupiter has no solid surface. It's atmosphere becomes thicker and thicker as you descent deeper. At some point you will hit a fluid, probably a liquid hydrogen sea.

How come a New earth moon is not on a possible disaster list? by Justin L Q: You know Luna (earths moon) controls the tides and helps us have 24 hour days right. Well what if a very Large asteroid say like 4 Vesta gets caught into earths orbit wouldn't that cause serious Issues on earth.

A: if something with any size did become moon like to earth yes it wuold effect everything from tides to time to seasons to weather etc. the likliehood of this is slim to non. especially since our life is so short and in space things take a along time to happen.

What is the energy flux from the earth neglecting the sun? by sdrc92126 Q: Earth is very hot in the interior and this heat eventually escapes into space. What is the rate of this energy loss in W/m^2?

A: As I recall, the flux caused by the heat in the earth's interior is about 0.55 W/m^2. This is not much compared to the 100-200 W/m^2 that we get from the sun.

What acceleration would you have toward earth if you were halfway between the earth and the moon? by uc0nnh00ps Q: If you were located halfway between Earth and the moon, what acceleration would you have toward earth? Earth-Moon separation is 60 Earth radii.

A: ma = GMm/r² a = GM/r² G= gravitational constant M = mass of earth r = distance between center of earth and you = 30 earth radii in your case. Calculate :)

How is the earth's temperature related to weather change? by T Q: I understand why the earth is heating up, but why does this effect climate change? Why are weather conditions more extreme due to a warmer earth?

A: Actually, weather conditions are not becoming more extreme, but with expanding populations and building, extreme weather events are having larger and larger impacts. Climate change in itself has always occurred and is normal for the Earth.

Earth's Surface is constantly absorbing energy from the Sun. How does it get rids of the heat? by Kirk Q: Earth's Surface is constantly absorbing energy from the Sun. Explain why the Earth's surface does not continue to heat up.

A: You're right, we're constantly getting bombarded by thermal radiation. If the earth had no way of cooling off, it would simply keep getting hotter and hotter. So the we must have some way of cooling off, some way of losing energy to space, because we can't just sink it into the oceans, or ice caps. When light shines on the earth, different places heat up by different amounts. Snow reflects most of the incoming light, so snowy areas tend to stay cool. Dark areas, like black parking lots, absorb incoming light, and so will warm up (urban heat island effect). In order to keep at a relatively constant temperature, the earth must get rid of energy too. And it does: As emitted thermal energy (EM infrared), that is transmitted to space. Space is very cold. Only about 3 Kelvin (-454 F). The hotter something is, the more infrared emitted. Clouds absorb or reflect the infrared from the surface and send it back into space. Deserts are hot during the day (well, what we usually think of as "deserts"), because they absorb a lot of incoming radiation, but at night they radiate energy back to space, so they get quite cool (one of the extreme dangers of trying to survive in a Sahara or Kalahari-style desert). As already stated, the "bright white" ice and snow reflects much of the thermal energy off of our planet (take a large piece of white paper out at a bright, sunny noon, and an equally large piece of darker paper, and sea which one is easier to look at - the white will probably make you squint). So, to keep blabbering on for you... The average albedo (reflectivity of the globe as a whole) of the Earth is about 0.3, which means that 30% of the solar energy is reflected back into space, while 70% is absorbed by the Earth and re-radiated as infrared (molecules will absorb energy, then they re-emit it; sounds funny, but that's what happens). The planet's albedo varies from month to month, but 0.3 is the average figure. It also varies very strongly around the glob: polar ice sheets have a high albedo, oceans low. Here's how it breaks down as far as thermal energy directly reflected. 6% reflected from the atmospheric gasses 20% reflected from clouds 4% reflected from the ground (including land, water and ice) The remaining 70% of the thermal energy is absorbed: 51% absorbed by land and water, then back out again in the following sub-types: - 23% transferred back into the atmosphere as latent heat by the evaporation of water - 7% transferred back into the atmosphere by heated rising air - 6% radiated directly into space - 15% transferred into the atmosphere by radiation, then re-radiated into space 19% absorbed by the atmosphere and clouds, including: - 16% reradiated back into space - 3% transferred to clouds, from where it is radiated back into space When the Earth is at thermal equilibrium - happy and healthy - the same 70% of sunlight as thermal energy that is absorbed is again re-radiated: - 64% by the clouds and atmosphere - 6% by the ground However, we humans are throwing our happy planet off-kilter (depending on the scientists whom you want to believe). Global warming is a fact, but is greenhouse warming (i.e. human pollution) the problem? Maybe; decide for yourself. The largest and best-known apparent human impact is from the well-mixed greenhouse gases (CO2, CH4, halocarbons, etc.), totaling an increase in forcing of of the retainment of thermal energy. Currently, it represents less than 1% of the solar input, but may contribute to the observed increase in atmospheric and oceanic temperature. Considering that 1% is actually a lot of heat, that's why it's being addressed as a global problem.

How do you calculate the gravitational attraction between the earth and something in Earth's orbit? by Molly M Q: Example: Earth's gravitational field is 7.97 N/kg at the altitude of the space shuttle. At this altitude what is the size of the force of attraction between a student with a mass of 42.5 kg and Earth?

A: You'll need to know the earth's mass, the distance between the center of the earth and the center of the object, and the universal gravitational constant. Then plug it into this formula F = G(m1m2)/r^2 Where F is the force of attraction G is that constant I spoke about above m1 is your mass m2 is the earth's mass and r is the distance from the center of the earth to your center.

If I start walking across the earth, how long would it take to return to the exact point where I started? by ButterMilkQueso Q: Since Earth is a sphere.

A: Well, since their are obvious bonudaries you will cross such as oceans, buildings, etc. The Earth's circumference is 24,901.55 miles. If you could walk across the Earth, if you were walking 3 miles per hour. It would take you: 8,300.51667 hours or 345.854861 days or 11 1/2 months or almost 1 year Don't forget you would need to stop for breaks, eating, sleeping, etc. So in that case you would at least double your trip's time frame. So then it would simply be generally 2 years.

How long the earth will remain a suitable place for humans to live? by evan_jb Q: We know that global warming is destroying earth. The earth becomes more unfriendly by the day, and only few people try to reduce global warming, most of us don't even care about global warming. So eventually the earth will become an unfriendly planet. How long will the earth becomes an unlivable place for humans if there aren't any environmental actions done? What's the best action to counter it? I forgot this, but please also state the reasons of your answers.

A: Global warming and the depletion of resources such as coal, oil, gas and water are very serious problems for mankind but the earth is unlikely to become uninhabitable in the foreseeable future. However, if we do nothing about these problems we will suffer very severe social and economic disruption and a further increase in wars. Mass starvations, migrations, wars and plagues could decimate the human population and leave the survivors scratching a living without any of the technological supports we currently enjoy in the developed world. The solution is to adopt a simpler lifestyle supported by technology rather than go on using technology to waste the world’s resources. (As indicated above the alternative is to have a simple lifestyle forced upon us by exhausting the resources so that technology will not be available to provide comfort). We need to demonstrate to our politicians that we will welcome sustainable policies (e.g. no more airport runways) by adopting simpler lifestyles individually. Travel by public transport and by walking and pedalling. Work, shop and socialise locally. Stop buying stuff and taking foreign holidays just to keep up with the neighbours. Repair and re-use stuff. Recycle what can not be re-used. Having reduced demand for stuff and the energy needed to manufacture, distribute and dispose of that stuff we need to use technology to develop further resource saving measures (e.g. insulation) and to develop sustainable energy resources (e.g. wind, wave, tide, hydro and solar). These are exciting challenges and opportunities for employment. The good news is that a simple lifestyle based around local services is healthier (walking and cycling improve fitness and enable you to enjoy other activities more) and more fun than trying to keep up with the neighbours. By adopting such a lifestyle you will demonstrate this to others. Best wishes

What is the earth's maximum capacity to absorb human population? by cricket Q: Right now earth population is 6.5 billion. What is the highest limit that human population would ever reach? And what is earth's maximum capacity to absorb humans? With so much pollution, waste, deforestation, environmental damage, etc etc how long is it before earth will perish simply because too many humans exist?

A: There isn't a real number for this quesiton because it depends on so many variables. For instance, if everyone was super conscious of our environment including all governments and corporations and everybody worked hard to recycle and find better ways not to pollute, more efficient and non-toxic way s to deliver energy - we could have a lot more people on the planet than if we didn't give a crap and determined our pesonal welfare today was all that mattered. Maybe we passed the optimum around 1600 or so, but that's hard to say because the distrubution of humanity was very uneven. Compare Europe and Asia to the Americas and Africa. The former were densiuly populated and breeding disease and mass wars whereas the latter was not densely populated and their disease and wars were smaller. If they hadn't been invaded by the "civilized" countries they probably could go on until the planet burned up. On the other hand we enjoy more comforts and a longer life. Would you want to die of appendicitis? Or an infection? I believe the hope for humanity as a species, is to be able to use our huge brains to regulate our population size to an optimum in conjunciton with Earth's ability to sustatin us. If we don't then Humanity will be just a blip on the screen of Earth's life.

How far from the center of the Earth is the center of mass of the Earth–Moon system? by Bluebell Q: The Earth has a mass of close to 6.0 • 1024 kilograms, and the Moon has a mass of 7.4 • 1022 kg. The center of the Earth is 385,000 kilometers from the center of the Moon.

A: The center of mass for the Earth - Moon system is approximately 1,710 km below the surface of the Earth on the side facing the Moon. That is 4,666 kilometers from Earth's center so that center of mass is far closer to the surface than to Earth's center. .

What would happen if the Earth rotated the opposite of what it does now? by F F Q: The Earth rotates clockwise around the sun, right? What would happen if it suddenly rotated counter clockwise? How would life be different if the Earth normally rotated counter clockwise instead of clockwise? Sources? Why or why not wold the difference in rotation effect life on Earth?

A: It depends on whether you mean the spin of the earth on its axis or the revolution of the earth around the sun. The way your question is worded it sounds like you are talking about the direction the earth revolves around the sun, and theoretically it shouldn't make a difference whether we revolve clockwise or counterclockwise. A year would still be a year.

How will planet earth look like if it is viewed from another planet? by Hisoka Q: Will planet earth look like a blue star from another planet's sky? If yes, is it possible that somewhere in the universe earth is not named as "earth" and is also considered a "heavenly body". Then, are we considered as "heavenly beings"? Are we viewed as a part of another planet's heaven?

A: Well, ..., Yes, the blue characteristic is preserved. Here are some that were taken from Mars. From Orbit: http://www.nasa.gov/mission_pages/MRO/multimedia/mro20080303earth.html From Ground: http://www.google.com/imgres?imgurl=http://www.bigpicturesmallworld.com/images/Mars_to_Earth.jpg&imgrefurl=http://evadot.com/2010/12/27/13-stories-in-2010-that-defined-space-exploration/&h=1007&w=1194&sz=392&tbnid=TmV3_yw_au9-SM:&tbnh=94&tbnw=112&prev=/search%3Fq%3Dnasa%2Bearth%2Bfrom%2Bmars%2Bspirit%2Bpicture%26tbm%3Disch%26tbo%3Du&zoom=1&q=nasa+earth+from+mars+spirit+picture&docid=vezNG48KCkH0vM&hl=en&sa=X&ei=dEJFT9HUK4nftgexoNySAw&ved=0CDAQ9QEwAQ&dur=527 Earth from Voyager I just after it passed Pluto: http://planetary.org/image/PIA00452.jpg http://planetary.org/image/voyager1-earth-pale_blue_dot.jpg

How to make the earth to rotate around itself again if someday it stops? by Rajendra Q: If earth's rotation is getting slower and slower every moment, then how to accelerate it without any damage caused to earth? Explain with available laws and principles. Only a professional answer is needed. No jokes. And one thing more, never say it'll never happen. It is illogical cause if some very very big asteroid after 5000 years will hit the earth from the opposite direction of earth's rotation then it will cause the earth to stop rotating. And again, from over 4.5 billion years the moon has slowed down the earth's rotation speed from 6hours to 24 hours. So don't tell it'll never happen.

A: This is not a serious question with regards to the Earth. However, a very related question has been posed concerning the terraforming of Venus, and how one could spin-up Venus to a twenty four hour day. As you have already stated, this could be accomplished with precisely aimed asteroid impacts. A less violent method would be to create an artificial Venusian planetary magnetic field with its axis oriented at 90 degrees from the rotation axis. Other artificial magnetic fields could be created on "Near Venus Object" asteroids, Using magnetic attraction/repulsion strategically in such a way as to increase the spin of the planet as the asteroids zoomed past. This scheme would subtract energy from the asteroidal orbital motion and convert it to angular motion of Venus.

The rocks on Earth are much younger than the earth itself. How does this support the theory of plate tectonics by Stoika Q: The rocks on Earth are much younger than the earth itself. How does this support the theory of plate tectonics?

A: The rocks you typically find are younger than the Earth because the surface is being renewed. As plates collide, some rock is thrust under and melted while other rock is lifted up. That rock that has been lifted to the surface either by volcanic action or tectonics is considered "new". The base elements are older, but the actual cooled, formed rock is a new combination. Think of plate tectonics as a huge, incredibly slow, rock recycling system. These new rocks show that plate tectonics brings molten material up from beneath the crust and leaves it at the surface. Also, by the way, erosion breaks down rock into sand and particles that collect and over time compress to form new sedimentary rock (sedimentary rock is also created by the stuff left behind on the seafloor by microscopic ocean life over log periods of time) which is often much younger than volcanic or igneous rock formed from plate tectonics.
