Would the earth survive ?

We would stay in essentially the same orbit around the sun and gravity on earth's surface would remain normal.\nTides would be solar-only, about 1/2 to 1/3 what we have now. (Lunar-only tide amplitude is about twice solar-only tide.) This change would cause a major adjustment to shore life and possibly to birds that travel extensively over ocean waters but would not be disastrous to land-dwellers. Loss of night-time illumination would affect nocturnal animals somewhat, but they do without moonlight for several days per month as it is. Bottom line, not a major threat.

Yes the earth would move but not that anyone would notice.\n\nEvery time you push off from the earth, the earth moves \nat a velocity equity to -your_velocity* your_mass/earth_mass.\n\n6 billion people would be less than 600  tons while the earth is about 5,972,000,000,000,000,000,000 tons

I'm sure the Earth would think so...\n\nhttp://threeleggedlegs.com/humans/

If the Tooth Fairy waved her magic wand and ...\nAre you serious?\nDividing the Earth in two parts without damaging the surface would require ... magic.\n(Of course Arthur C. Clarke did once point out that any sufficiently advanced technology would appear as magic but we're talking an asteroid strike, not super-technology.)\nIf a body large enough to blast the Earth apart struck, there would be nothing presently on the surface that would survive in recognisable form.\nI suppose it's imaginable that two bodies mutually orbiting a common center of gravity, might accrete from the resulting debris. The oceans would have been vaporised. Some water would recondense and wind up on our hypothetical twin Mini-Earths but I imagine on the whole they'd be pretty dry. Bacteria living in deep crustal rocks blown clear of the remains of the planet would probably  survive and as this debris was gravitationally 'swept up' over time by the newly formed pair of mini-Earths life would be re-seeded and we'd be back at 'Square One'.

Well.. \nI'm more scientific than religious in this matter. \nThe reason Earth has life is because of the certain climate, temperature, etc. which is perfect for life. \nHowever, there are always news stories about "possible life on mars" and as such. And I believe that for life to form, there needs to be a certain set conditions which allow life to be formed and which support and maintain it. \n\nTherefore,  most definitely there could have been life in other planets, maybe some organisms or something else which is suited to that planet's climate, temp. and etc. It could be that we either can not detect that life on the other planets or the planet is undergoing some sort of climatic change which does not support life due to variant pressures. \n\nDid god stop at Earth-- well, that is a question which is a matter of belief- if we consider god as a positive force which stimulates life- then no, god wouldn't have stopped only on Earth. \n\nSome research even claims that there are other solar systems with other stars (like our Sun) in which a planet is very like Earth- almost same which supports life. \n\nSo, whether life is or not- is a personal decision. I think there is- but as you say, there is no real solid evidence supporting or contradicting existence of life in other planets

I'm afraid you asked a loaded question.  I don't believe humanity *can* survive exponential growth of its population for very much longer.  I don't know if our species has years or decades remaining... but it seems unlikely we have centuries unless we make drastic changes.\n\nAs I look, right now, the world population, according to my source below, is 6,627,722,573.  \n\nI agree with what little I know about Albert Bartlett's views on population growth.  For years I (and many others) have said that unchecked growth is a grave danger.  We simply do not have the material resources of fuel (for transportation and electricity) and food -- and ultimately space -- for population to continue to grow indefinitely!\n\n'People, people, and more people' is the engine at the root of a great deal of what is wrong with the world, and is arguably responsible for a dwindling enjoyment of life on this planet -- Earth  is of limited size, after all.  \n\nTake *unchecked* population growth to its seemingly-absurd but perhaps inevitable conclusion -- we are so physically restricted that we can no longer even move.  Or maybe we run out of food long before then.  Or growing stress and intolerance has sparked a global war.  Or a new or mutated virus has destroyed hundreds of millions of people in a matter of months, thanks to our close quarters and constant global movement.\n\nIronically, it might be a virus that saves us -- or, at least those of us who survive.  Freed of the need to compete for food and whatever fuel generates our electricity, they would at least have *some* of the resources our ancestors did.  Of course, even those things may be scarce if that global conflict I mentioned sparked a nuclear war.\n\nBut besides all the doomsday scenarios that could happen, our quality of life must suffer -- must already be suffering -- from our incessant reproduction.  Unless we live in the ever-dwindling rural areas of the planet, we are increasingly bombarded by noise, rudeness, superficiality, the tick of the clock, and the intolerance of our ever-closer neighbors and highway "companions" (erroneously implying they are pleasant to be around).  The person in the next car or house probably feels the crunch of space and time just as we do, and stress is a growing problem.\n\nWhere there are more people there is more anxiety and fear, more intolerance of rudeness -- and more rudeness! -- more consumption, more noise, more constant construction and change, leading to increasing interruptions to our movement, and an increasing sense of instability... more stress (which is a catalyst for further reductions in many of the aforementioned areas)... and... less peace of mind, less fresh air, less reasonably-priced and readily available food (at some point), less awareness of nature (the sound of a stream having long been drowned out by the honk of the horn and the rumble of the engine; the chirp of a bird having been obscured by the chirp of the Nextel, and the violence-inspiring thump of the boom car)... I could go on and on.\n\nI believe we are causing our world to evolve (or at least change; evolution implies improvement) faster than we, ourselves, are evolving.  That strikes a dangerous chord in my mind.\n\nThis is to say nothing of the other species--plant and animal--we share the earth with.  There is a need for them, too, not to mention a birthright of survival for every animal on earth!  \n\nI'm not as sure as I once was that we are heading toward these terrible conclusions... population growth isn't the rule in every country of the world.  Indeed, there is a dwindling population in some places, and I wish I could say where, but I don't know.\n\nBut spend some time in a national park -- some real, quality time during which you *begin* to get a sense of what peace of mind is about, and how beautiful the *entire* planet once must have been -- and then tell me we don't have to pay close attention to the

actually we saw a movie about this in science, we will not be alive because there will be an ice age that happens in cycles. think about it, we will not last because we do bad when it is only 30 degrees f outside. plus, 1 million years is not that long for evolution compared to the eras is the past ex precambrian was 3900 million years long.

Yes, I do because Earth is not a closed system. If it were, meteorites would never hit.  I have an interesting comparison (to me at least)  about comets "seeding" the earth....... have you ever noticed that earth resembles an "egg" and comets resemble sperm?  they have heads & tails like sperm...... and the term panspermia......... just a thought.......

Yes, we could. We all will probably die at some point. As far as a mass extinction is concerned, who knows? The future is pretty much unwritten.

Any life form as we know it could never live on Uranus. Of course, I think it's a bit arrogant and short-sighted to think that we know any and all forms that life can take. After all, life exists at the bottom of oceans where it was once thought living organisms could never survive. We have such a small perspective so far that there could be many forms of life that we can't currently imagine. Only time will tell.

I think we'll screw up the atmosphere, then choke to death.  1000 years later, the Earth will probably fix itself, sans us.

It is a very good question.  Just looking at entropy at a universal level, the earth as it is now is not very probabably.  On the other hand the formation of galaxies, stars and planets follows the entropic evolution of the universe quite well.\n\nGiven you have well over 100 billion galaxies, each with 100 billion stars, even very low probabaility events should be around.\n\nAlong these same lines of considering all the things that are low probability that helps make earth the happy place for life that it is, especially with regard to the search of life elsewhere, I recomend you take a look at the book "Rare Earth," it's not militant wackery, but rather a look at all the things that might make earth faily unique in it's ability to harbor advanced forms of life.  It was written by a pair of very well respected scientists from the University of Washington.

Yes, we will discover other planets that also sustain life, and we will do so within our lifetime.  I do not mean that we will physically go to these planets but we will discover this by placing much more powerful telescopes in orbit around Earth.  There is a definite signature that we will be looking for and that will be the presence of Oxygen in another planet's atmosphere.  If a planet does not have any oxygen in its atmosphere then it would not be able to support life.  There was a time billions of years ago on Earth when there was no oxygen in the atmosphere and at that time there was no life on Earth.  We may not discover other intelligent life on other planet's during our lifetime but i am sure that we will discover other planets that are supporting at least plant life if not primordial single cell life as well.

While I agree with other people here that we should take better care of our planet, eventually the Earth will be destroyed.  Even if all comets and planet-killing asteroids miss us, the sun will eventually expand into a red giant and engulf the Earth.   Though that isn't likely to happen for possibly another billion years, it will eventually happen.\n\nThat being said, the more planets that we as a species inhabit, the greater our chance of survival.  Especially when we consider the possibility of colonizing other worlds in distant solar systems.  The endeavor will not be an easy one, and is indeed not possible at our current level of technology.  However technology may eventually advance that allows us to traverse great distances of space in but a few moments, perhaps through the creation of artificial wormholes.  Maybe we'll be lucky enough to see it in our lifetime.

i think you have answered your question pretty well. i think we will be dead by the time this is possible, but i do think we can find/inhabit a different planet in about???????????years. and as far as the bible goes, fiction novel. its hard for me to believe that so many peoples lives revolve around this book. god and santa are laughing it up with the tooth fairy and the easter bunny, while millions of weird-o's stand sit kneel, stand sit kneel....crazy

Everything today survives.\nAnd that is not the way nature intended it to be.\nWe keep sick people alive who normally wouldn't make it.\nWe keep children alive who would have died at birth and now are living breathing little vegetables.\nAnd that is supposed to be progress?\n\nOk,  I stop now.  I think you were looking for somewhat a different answer....smile

Hi. I read your other answer. See below. The atmosphere is almost 93,000 000 miles away, so don't worry. Earth is more that just wonderful. It is exceedingly rare in my opinion. Together with the Moon, her oceans, her temperature, her atmospheric environment - all these make for an unusual combination of life supporting qualities. We should cherish this home we have.\n----------------------\n"This is wonderfull idea! Just imagine if could expand the size of our tiny little planet.\n\nOn the downside though, it is believed that the dimensions of earth is perfect for the exixtence of life on it. if we made her any bigger, our atmosphere would be too close to the sun, and earth would fry like a tomato.\n\nJust my opinion."
