Why won't the sun burn forever?

Answer 1

no. the sun has been around for almost 5 billion years now and scientists predict that it will still continue to be up there for around 5 billion years more. that means that the sun has consumed half of its life already. when that time comes that the sun has already consumed all the energy inside it, it will expand and take in all the planets that surround it and then it will shrink and turn into a dwarf star until eventually it will turn into a black hole or something. others also say that there will be a supernova once that time occurs.

Answer 2

Eventually it will run out of fuel. The sun is currently "burning" Hydrogen by converting it to Helium. But don't worry, the sun has a lot of Hydrogen left, enough to last for several billion years.

Answer 3

Yes, it will burn out; the Sun uses fuel, and eventually, it will run out of this fuel. Note that this is not a normal chemical reaction; the Sun uses nuclear reactions. But it is fuel nonetheless, and the amount of its fuel is finite. The hydrogen atoms fuse to form other heavier elements and continue to do so until it has run out of hydrogen atoms. Then it cannot hold its surface in place and will swell into a red giant before exploding and probably shrinking back into a white dwarf.

The Sun is expected to run out of fuel in approximately 5 billion years.

Answer 4

The sun is said to turn into a red giant and killing he human race and all life on earth. It cannot explode because it is too small.

Answer 5

Ya, I think it will disappear when dark energy expands and pushes each galaxies against each other.

Answer 6

The Sun is not going to last forever. It will be around for about another 5 billion years and die out when all of its fuel has been burned up.
