When is the world going to die?

Answer 1

The sun has about 4.5 billion years left before it's lease expires, but the earth will be uninhabitable - incinerated, in effect - well before that, but you don't need to worry right now. Most astronomers thing that life on earth will become untenable (because of temperature rise as the sun expands), in about 1.5 -1.7 billion years. In about 3 billion years, give-or-take, the earth will be inside the sun - or what's left of it.

Answer 2

We do not know when the world will die. Scientists have not figured out when. There are many answers: some say the world will die in 2010, or in billions of years.
