what will happen  if our earth is empty?

Well if you mean in terms of humans.  It would probably begin to recycle itself, Cars would rust, buildings would crumble from weathering, Animals would again flourish back home. and everything we thought about how to live would have to start from scratch if you believe in evolution.  But then again, earth has been destroyed about 30 times, from the results of asteroids, meteors, ice age and drought. but life did find a way right?... \nNow if you mean Earth completely empty of life all over animal or plant...  well then it would probably look like mars or a moon void of life and boring. with some clouds i guess.. Hope i answered correctly to your terms.

Yup. The latest will be 5 billion years from now, give or take a few hundred thousand. By then the sun will either:\n\n1) engulf our planet (very unlikely, but will come close enough to vaporize our planet)\n2) Die and not engulf or vaporize our planet and within days our atmosphere will freeze and fall to the earth in the form of ice.

You get rid of all the balance on our planet!  It would mess up the ecosystem and the food chain therefore all the living creatures on Earth, including people.  Everything effects everything else.  I imagine that they weather would go crazy or at least not function like we know it.  The domino effect would go out of control.  Unless, our planet could find another way of keeping the balance we are all screwed.

What would happen is we may all die.  What we would do.  Hell get any last piece of ass I could find.

Nothing will happen man. It's vacuum out there, no nitrogen CO2 and so on.. so no decomposition can take place.

Absolutely.  \n\nHow long depends on what you consider destroyed.   Chances are we'll be long gone before the planet is left abandoned by our own dieing sun which is about 1/2 way through it's life cycle.  From the linked Wikipedia artical, it claims that the earth won't be engulfed and vaporized by the sun, but it won't be a good thing one way or the other.\n\nWhat happens after we have no sun is tough to say, but you could probably argue that at that point if not long before the earth would be unable to support life.

The world would come together in panic ... "Where the &*^^ did the US go?"  Conspiracy theorys would abound.  Tensions would be high - no one would trust anyone else.  Did an experiment go wrong?  Did one country develope an incredible weapon?  Are the aliens finally attacking?  Did God decide simply to wipe them off the face of the earth?  Different groups would claim responsibility -- most of them groups no one has ever heard of.  And all over this great world, there would be office pools involving which country would disappear next.  (My money would be on Akrotiri - but really, if they disappeared, who'd notice?)

*Shrug* Depends on your beliefs. Do you believe in God and an Apococlypse? Do you believe that the current state of affairs in the world is so f^#$ed up that we'll either blow ourselves to pieces, die of disease, over-population, crop failure, or poisoned water before our grandchildren are born? \n\nThe answer is we don't really know. It depends on how wise we become in the next few generations, and whether we (meaning, humanity) can get our enviormental pollution, war-mongering, and population growth under control. Hypothetically speaking our planet won't be destroyed until the sun becomes a red giant in approximately 4.5 to 5 billion years. So humanity, if it never developed space travel, could last that long. But unless major changes are made in the coming fifty to one hundred and fifty years, we may well be facing yet another mass extinction of life on earth (this wouldn't be the first major extinction...).

it won't be for a long time from now, like 1000s of years, but it will happen.  Planets are basically stars and stars burn out sooner or later.  If it isn't earth that ends first, it'll be the sun that burns out and we can't survive without the sun.

we will never know whats going on out there if we dont explore it.\nmaybe there is aliens out there who would want to communicate with us or there may be some asteroid out there that is going to hit the Earth in near future.

listen to t. h. white (sword in the stone author). we will in the end use up all our resources and the organisms that need them will die. it will break off part of the food chain and no other organisms will be able to live. the part of that is what happened to the dinosaurs (likely) and it will probably happen to humans considering how destructive we are.

The leavings would have no mass, no length, no width, no depth, no measurements of any kind and there would be no beings in existence, sentient or otherwise,  to perceive this lack of existence so nothing would be here not even here would be here. It would be nowhere.

Continents will grow and hell will freeze over!~ polar caps will dominate the poles causing the earth to wobble throwing precession off wack pure kaos!!!! terrorism will end though!

we might freeze to death. depending on the  global warming nuts.

If the world suddenly turned into a tangerine, it would burn up and start to "fall/move" twords the sun.  It would probably split apart, and no life would survive.\n\nHowever, the chances of that happening are very, very slim, and If I were you, I wouldn't worry about it.  I mean really, really don't worry about it, there is a better chance of the world turning into an overcooked Mud Pie, so that is what you should be worried about instead.

The world system as you know it will end with fire. It will burn up. In other words it will be recycled just as anything is that is burned with fire, changed and put to another use.\n\nIs that simple enough. When, only God knows. \n\nThe nice thing is you do not have to worry about it because there is a way out for you. Read a bible in your native tongue and find the answer. If you can not email me. cjkeysjr@yahoo.com.ph and I will give you my opinion as simple as I can in such a way a little child can understand. That is a promise. \n\nAfter that the rest is up to you to do or not do OK.

Yes.  The sun will blow up in about 4.5 billion years, taking the earth with it.  Odds are humans will have been gone long before that though.
