Question

If the sun does explode in the far future, what would make it explode?

In: Physics

Answer 1

The Sun is a gigantic nuclear reactor. It produces a lot of energy, and in the case that gravity collapses the core, it can release a lot of it at once, in the form of expansion and explosion.

Also our sun won’t explode, bigger stars do though.
