Question

Ok, what do you honestly think will happen to the world at the very end of it's exsistence? When do you think it will happen and what will make it's end come about?

Example of what I mean- Earth will end by being sucked into a black hole, it will happen in two years, because everyone is getting so overweight it's throwing the earth off balance in it's orbit. (This is not a real situation just explaining how these three questions should be answered.)

Answer 1

The Earth will be consumed by the sun as it begins to grow to an enormous size, as a part of the sun's death.

Answer 2

It will be consumed by the expanded sun.  The best estimate for the time line is 1-2 billion years (that's billion with nine zeros).

Answer 3

Wow, I am really happy  that was just an example. You had me worried for a while.... ;^)

Our solar system might get booted from the suburbs to the boondocks of our galaxy when the Milky Way merges with its neighbor Andromeda in a few billion years, scientists say.

   New calculations by T.J. Cox and Avi Loeb of the Harvard-Smithsonian Center for Astrophysics show there is a small possibility that the Sun and its planets will be exiled to the outer reaches of the merged galaxy

But first it has to last that long....People often talk about the planet being wiped out by a direct meteorite strike, but how about some distant planet being wiped out like neptune and then that throwing the entire solar system out of balence...

Answer 4

In about six billion years, our sun will become a red giant.  This means that it will get bigger and bigger until it envelops the orbits of the inner planets as far as Mars.  Before then, however, the oceans will boil away and all live on our planet will become extinct.  The planet itself, however, will last quite a bit longer, but it will be as lifeless as the moon.

Answer 5

400 million years from now

Sun losses it's mass and becomes light thus making earths and every other orbit expand.

Sun won't gallop us but Due to it's mass being less than the Chandrashaker limit it would blast away it's outer layers.

During that time earths atmosphere would fade away due to the sudden impulse of the Blast.

Gradually sun would cool to black dwarf and all the planets would never receive light i.e. 24 Hr night.

until some other thing like black hole appears nearby our earth other wise it would be floating in space.

This is one of the most accepted probability. There are many others but are proved wrong.

Answer 6

The Earth will be destroyed by the sun, when the sun finally explodes. This will happen many thousands of years from now. The sun is a star. New stars are born every second from gases and dust of the "dead" stars, those stars that exploded. This cycle goes on and on. The universe will never come to an end.

Answer 7

When our sun becomes a super nova in about 5 billion years, the Earth will either be swallowed by the expanding star or everything on it will be burned to a crisp and all the water will evaporate.
