how many years till the end of the world?

Answer 1

There are many myths and legends about this subject. However lets try and answer this and not speculate or fantisise. This planet began about four to four and a half billion years ago. This is a result of scientific investigations-not myths, legends, fantasies, fair tales, imaginations or presumptions. And like all planets it has a finite life span. Here below lies the possibilities:

I:

The greatest danger that the earth faces at this momement is a collision by a large chunk of rock from space-an asteroid. These things travell at relativity speeds-that is speeds of thousands and tens of thousand of miles per hour and greater. At these speeds energy is multiplied a hell of a lot as per the theory of relativily. E=MCsquared. That is the energy on impact equals the mass times the speed of light squared If an object say is 100 yards across and ways billions of tons, it is multiplied by the speed or proportion of the speed of light and then squared. In other words the mass times the speed squared. Therefore an object such as this hits at such an impact that a 100 yard object would wipe out an entire county. An object about a mile wide wiped out the dinosaurs, 65,000,000 years ago. An object much bigger would wipe out all life on earth. Many billions of years ago an object the size of Mars impacted upon the earth. It almost destoyed it. Therfore the end of the world could come tomorrow with the right circumstances. However it is not likely, but we know some day a body is bound to collide with us. It is only a queston of when. And if we don't take steps, the end of the world could be in a few years, or a few centuries.

II:

If we continue in our present vein of enviromental neglect then after a few thousand years, we could , by sheer population and technology make our planet unlivable by hman beings. We may even have the technology in say, a few tens of thousand or hundreds of thousands of years -and the necessity of living space, to have to dismantle our planet to create more living space. This would be because we would use the third demension of the space of earth, as we now only use about two, and use more of it. There would most likely be protests and I personally hope it wouldn't happen. I think that love of this planet would prevail.

III:

The sun which is about 5,000,000,000 years old also has a finite life span. We depend on the sun for life. In about 5,000,000,000 years, give or take a few hundred million, the sun will go nova. It will burn out all it's hydrogen. Then it will start on it's helium and so forth until it finally reaches the heaviest element of all-iron. Now iron takes more energy to burn(by nuclear fusion as the sun does for it's energy) and thus the sun will begin to collapse in on itself. It will have one last burst of energy and grow. Mercury and Venus will be swallowed. The earth will get hot, too hot for life. The oceans will begin to boil and the atmosphere will be lost. Many other planets in the solar system will be effected. The gas giants, or at least some of them will be stripped of their atmospheres before the solar wind of the nova. The earth will die and about 5,000,000,000 to 8,000,0000,000 years hence will be no more but a hot rocky cinder in space or worse. Most likely in a few billion years time it will be the end of the world.

IV:

However the sun in going into nova will endeavour to weaken the gravitation pull to the earth. We might be lucky, very very lucky to escape it we can loose enough gravity to go far enough out so we can continue orbiting the larger sun. However in a few billion years after(if that), the sun will shrink again to a white dwalf-about the size of the earth. It will emit almost no heat and will be dead. So even if we survive the nova(the red giant) phrase, by about 8,000,000 A.D. or even less-or perhaps even a couple of billion years after that-the end of the world. If we possess at the time the technology(and I think we will) we might be able to manipulate the orbit. But unless we can create an artificial source of power to move our planet to another, younger star, by about say 10 billion A.D.- most probably at the most, it will still be the end of the world.

V:

Even if we accomplish all these things, the universe is finite. Even if we can manipulate far beyond our wildest dreams today-the end must come. Between 100 billion and 100 trillion years hence, all the stars will begin to die. By 100 trillion A.D. the last star will have fallen from the heavens. Surely by 100 trillion A.D. it will be the end of the world. At last.

VI:

However, we might have developed like nothing. We might be able to keep our old earth going. But the universe shall no be cheated. About between 1 quadrillion and 10 quadrillion years into the future, every planet will have left the orbits of their dead suns. They will be wondering around the galaxy. By about 100 quadrillion years or so the galaxy itself will not exist. The stars themselves will be gradually pulled by motion from orbit around the centre of the galaxy. Many will fall into the black hole in the centre. The black holes will grow, collide and grow again. In about 10 to the power of 21 years the black holes will take over the universe. There has been however postulated that there might be civilizations living and surviving around these blackholes. We may be one of them, on our beloved earth. If we can survive all those natural cosmic catastrophies.

VII:

Nothing can escape a black hole-except heat. For the law of entrophy states that heat will go from where it is to where it is not. Not even blackholes can stop this. Eventually the blackholes will begin to evaporate-loosing energy in the form of heat. First the small ones will disappear, then the very largest. By about 10 to the 120 power years all blackholes will have died. Surely by about this time it will have been the end of the world. However we might be so advanced that we can even survive this. Even if we do the universe will deteriorate. Eventually there will be a deutronium sea. Long after that there will be only atoms-the size of present day galaxies. That is their neutrons and protons and electrons will orbit that far out from their neucleus'. Protons and even Positrons will begin to decay. Surely by about 10 to the 500 power years that will be that.

VIII:

Now let us presume that we will become so advance that we can somehow survive even this. We probably would have to take on different forms-most likely not material. We might however be able to preserve the earth itself. Say as a valueble and much loved museum piece. A piece very very important to our history. We may become multi demensional. We may go to other and alternative universes. We may take the earth with us. But I have a feeling that somehow, somewhere, creation is finite, even if it is an unimaginable amount of finitability. For instance tunelling, the process by which by natural atomic decay and the process of change a lighter element without outside influence , by enthrophy decays or moves down to heaviness goes to being a heavier element. It is estimated that for a tennis ball to tunnel down to becomming iron would take 10 to the power of 10 and that to the power of 243. That is if you take a one and add 243 noughts-that numerical amount would be the number of noughts after a one. This number of years is the number of years it would theoretically take. Even with these huge numbers, so vast that they there written representations have to be written on many levels, I have a feeling that the earth, the world-us and everthing has a finite time-no matter how big. Even if we can eventually do everthing mentioned here, I have a feeling that everthing born(and the earth was born) will die.

For this is the noble story of creation. The birth, life and death of great things. Humanity, being intelligent, will most likely survive the end of the earth(the world). Having options of technology , advancement and places to go . But I think that eventually, even after all this time and most likely during it, humanity, and by that overall we could mean THE WORLD, will come to the fate of all finiteness-it will end. But the concept, the idea, the reality of existance, our existance and the existance of the world-the truth of it-it will last forever.
Hope this helps.

Answer 2

Being believers In God who started this world and the only one who knows when will it ends ,We see that the end of the world is not coming soon ,and there are Lot's of things to happen before the end .and these things takes a long time .longer than the time table we're hearing these days maybe in hundreds of years. so listen to you belief instead of fortune tellers .

Answer 3

Too difficult to say.
On the one hand there's asteroids, black holes and alien invasion; and on other, there's nuclear warfare, climate change and AIDS.

If we're really lucky we'll be destroyed in a couple of billion years time when the Sun becomes a red giant.

Answer 4

there is not an end to the world.......

but the Ancient Mayans think the world would end on December 21, 2012

but try not to believe that.....

Answer 5

there really shouldn't be a answer to this question because the bible say don't no man nor woman knows when the earth is going to end except jesus.

Answer 6

hi

Answer 7

4.5 billion years from now, our sun will supernova and our ol earth will be a burnt crisp. All other 'earth ending' scenarios people have listed above only related to human extinction....not the end of the world which you asked for....

Answer 8

how long can we keep rapeing the earth for all its worth or how many more landfills can we make and not recycle how much habitat can be destroyed or how much can not be salvaged and left unusable and full of garbage

Answer 9

Twenty two. Start packing.
