will life on earth ever end?

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.

The world will never end.  It will undergo progressive spiritualization, but great strides will be made in the mental and mind levels along this journey first.\n\nVast changes in the social and governmental structures will occur.\n\nThe next 1000 years will involve the most changes of all, but constitute only a very small part of the total journey.\n\nEventually, the world will join other perfected spheres.  \n\nThere is an amount of input from above both reciprocal to and approximately equal to what humans achieve.  \n\nAlthough humans do not exercise eminent domain in the true and final sense, once a mortal race is started on a sphere, they must evolve to perfection.  There are plans for transferring such a race of mortals to another sphere in the event some celestial calamity would destroy the entire planet.\n\nAlthough I know the foregoing for absolute sure, it took more than 50 years of seeking and study to determine this.  The certainty is not transferable, so you will have your doubts.  In that respect, you may wish to make some effort to check out the source.\n\nI would only remind you that Christ said, "Thy kingdom come, thy will be done, in earth as it is in heaven."\n\nThis is far from an idle wish.  It is a statement of fact, pertaining to the ultimate powers.

We live in a biosphere and air, gravity, etc are key components, if any of its constituent parts were removed and not replaced, life on this planet would end.

what is your question? of course the world will end at some point in time...but I don't believe you have proof.

LIFE HAS NO END !!!\n\nWHEN YOU LEAVE THIS WORLD YOU JUST GO ON TO THE NEXT ONE !!!

Of course, we're heading to the end of the world...in a few billion years, when the sun expands and consumes our planet along with the other inner planets. All life on this planet will be extinguished well before that happens. However, human beings may very well extinguish their civilization and themselves sometime in the next few centuries. The problem is not the science. Of course, many well-respected scientists have been speaking out on the problems humanity faces. While some, like James Lovelock, may think we have already passed the point of no return; other scientists argue that we are still within a narrow window of opportunity to halt and perhaps even reverse the destructive policies and technologies that are presently damaging the environment. \n\nThe real problem is humanity, its cultures, and its governments. Most people around the world still hold a world view based upon ideas that were held to be valid back in the Stone Age... many people even believe that some supernatural agency will rescue humanity and clean up the world as soon as things have gotten as bad as they can get. Meanwhile, most governments base their decisions upon corporate interests and upon national interests... thus more global problems and their solutions are pretty much ignored. Short-sightedness is the overwhelming curse of humanity and its institutions.\n\nLife will continue in one form or another on this planet, whether there are human beings there to observe said life or not.

I won't win points for originality by saying that the world will end as the sun expands as it gets older and becomes a red giant. As this will happen in 6 to 7 billion years time, it is not an immediate concern. There are various scenarios for the end of human civilisation or the end of life on earth but that is the most likely scenario for the end of life on earth.\n\nNo-one has a clear idea of how the universe will end. The most likely scenarios are:\n\n* the big freeze where the universe will expand so much that it is unable to sustain life;\n\n* the big rip where the universe will will expand so much that it eventually disintegrate into elementary particles; and\n\n* the big crunch where the universe stops expanding and starts contracting.

Afraid not.  The only planet in our solar system that has the temperature and atmosphere that will sustain life is good old Earth.

No one has yet shown that there is any life beyond that on Earth. \n\nAs far as life in general is concerned I am reasonably sure that there is life on other worlds and there are currently a couple of space missions in development that may find earth-like planets and even find signs of life on those planets in the next few decades.\n\nWhether there is intelligent life out there is more debatable.\n\nConsider that in 4.5 Billion years the Earth has only produced one technological intelligent species. This species has only really been able to consider possibly contacting or being contacted by intelligent beings from another world for the past 50 years. In that time we have just about managed to avoid nuclear annihilation, so far, and are currently well on the way to destroying the Earths eco-system.\n\nIf intelligent life is anything like Homo Sapiens then it will probably not last more than a few hundred years at a level where it is technically able to contact others.\n\nGiven that, it is extremely unlikely that two intelligent species will evolve close enough together to contact each other in the short time frame that they are able to do so.\n\nSo while there may be intelligent life elsewher in the universe I doubt we will ever find it.

the earth will probably not exist in the same fashion as it does today.  a meteor will probably hit us and start the life cycle again in the next 200 mill or so.  Probably more water and less land so i figure more water based life will exist

Assuming there is such a thing.\nAssuming that by 'we', you don't literally mean you and I.\nAssuming humanity doesn't destroy itself.\nAssuming the Universe won't end before.\n\nyes.

According to the Bible, the world will end one day in firey judgement.\n\nThe sun only has so long to burn, in any case.

Depends on some of your beliefs as to what you should believe on this one.  If you believe in evolution, we won't be humans more than likely.  We will have evolved into some other species, maybe more than one species.  That is assuming that human life did last long enough to evolve.  It is impossible to destroy all life on earth, but a nuclear war would more than likely destroy all human existence on earth.  So in essence, people would be eradicated.  But life would continue somewhere, maybe frozen in Antarctic ice or underground or at the bottom of the ocean.  And when the earth becomes livable again, that life will evolve again.  It will take different forms than what is here today, but it will continue.\n\nIf on the other hand you believe in creation, then God has promised that humans will be around forever, and the earth as well.  And it doesn't matter which religious book you go to (the Bible, the Qu'ran, the Talmud/Torah, even the Amida Buddha or any other book you'd like), they all say that God promised life to humans for eternity.  The bad ones are supposed to be removed in most of them, the exception being the Amida Buddha, which says all souls will learn to be good sooner or later in their travels through various lives.  They will do so so they can attain that which they strive for, Nirvana (or lack of want).  But humans as a species will survive.

It doesn't end.  It goes on. If you took a line and ran it in any direction off the planet's surface it would just keep going into infinity,  if you could freeze time and walk on that screen,  you would never get to the end.  There is no end.

If this happen?\nNo more people alive, and no more earth planet survive -\nBye, bye. . .

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

I am a Christian so I don't know when the world will end but until the God return to the earth again. At that time the world will full of disasters and countries fighting to each other,the animals and plants dying . The weather turn to very strange because of humans do not care of it .The devil want to take over the world but God will save us and give us a  life  can last forever ( which is more than 90000000000000000 years !!!!) if we believe in God. that's want I think will happened of the end of our world . You can read the novel called "Left Behind " to get more information that you might wanted or The Holy Bible .
