What will happen when the sun blows up?

Answer 1

A big boom occurs :L

Other than that, possibly all the other planets in its gravitational pull will all be pushed out at the same rate as the expanding explosion of the sun, thus saving us all.

The other alternative is, we all die due to radiation rather than heat, but if we all , somehow, survive the radiation, we will all be cooked, no doubt.

Reason: The sun is a star, so sooner or later it would die out. What would happen is the centre of the sun will get smaller and hotter. Outer layers will be pushed out further by this increased heat, so it'll grow in size. Becoming a Giant Red Star, it will grow to about a hundred times its size and will swallow up Mercury! Then, the sun would shrink to about no bigger than our Earth, changing its color from red to white and becoming a White Dwarf. After all that trouble, it would lose all its energy and heat to become a cold dark body, called a Black Dwarf, giving off no light or heat.

But don't worry, this wouldn't happen 'till 4.2 billions years later. So relax, it wouldn't affect you.

Answer 2
