Answer 1

The future , will be both amazing and depressing cause may be we find a way to protect the earth from asteroid or may be we will not be able to do so...
From the today's technology we can predict that the future will be good and the humans may be conquer over the problems of universe and win over the Harsh realities of the space ....

But there are certain things we can't to like the Andromeda galaxy, which will be collide with our galaxy and the others problem we could face in future...
But the artificial intelligence we will have in future may be helps us ...

hope that helps

Answer 2

that depends on the way we live on the Earth and use it's resources. If we continue exploiting the same number of resources at same rate, then final date could be very much before 2600 AD. But even if we find ways to sustain our species 4.5 billion years more, then the doomsday is inevitable. The sun would swallow up the Earth. the sun has enough hydrogen to fuse to last for 4.5 billion years more. After that it would fuse helium atoms to heavier ones till it reaches iron. Till now the sun has managed to counter the gravitational force of it's huge Mass by the force of nuclear fusion. When iron is formed in the core, no nuclear energy is released so the sun would collapse under its own gravity. Then the sun would explode into a supernova and all that would be left would be a red giant. thus if the doomsday does not come after 600 years, it will surely come after 4.5 billion years
