What would happen if the sun exploded?

Answer 1

First contributor said:

If our Sun exploded, it would destroy most of the planets, and kill us all.

Second contributor said:

Ok first that's true but it would take billions and billions of years for the sun to blow up.

Third contributor said:

That certainly helps us all feel better. But how do you really know that it won't happen tomorrow ?

Answer 2

the sun can't explode because it isn't big enough. The sun has already been around for about 5 billion years and has burned up about half of it's hydrogen fuel. In that case in the next 5 billion years or so it will completly run out of hydrogen and start expanding into a red giant. It will get atleast as big as Mercury's orbit buning murcury up and will mostlikely burn venus too and possibly (probably) but possibly earth. Then it will cool down into a nice small white dwarf then in a long time dissapear after a black dwarf.

Answer 3

I pretty sure that all the heat and radiation, plus the shock wave, would destroy Earth and a lot of other things around it. If somehow the world did somehow survive the explosion the world would freeze over in moments ,freezing and killing everyone in there foot steps.<---

LOONNGGGG story short EVERYONE WOULD BE DEAD

Answer 4

well if the sun were to blow up right this second, you wouldn't exactly know for the next 8 minutes. That's how long it will take the last remaining light from the sun to reach the earth.

After that, it will just be darkness, and seeing the moon will be on the other side of the earth while this is happening, there will be no moon either. So that means complete darkness! maybe a few stars.

but i wouldn't worry about it, because the sun actually expands and the sun will expand and burn the earth up wayyy before it will blow up. In fact, stars like the sun don't actually blow up... they eventually die.

Your question is just a hypothetical. It couldn't actually happen

I think that this could happen, anything is possible and this might really occur. Like you said, stars die. The sun is a star so it may die one day. Hopefully not any time soon, but it may happen.

Answer 5

If the sun were to explode, it would release an immense amount of energy in a catastrophic event called a supernova. The explosion would destroy the sun and likely cause severe damage to the solar system, potentially leading to the extinction of all life on Earth.

Answer 6

No. The sun is not massive enough to go supernova.

Answer 7

According to a book I read about the universe the sun will swallow Mercury and Venus and make the earth 1,000,000 degrees hot and the earth will be the new sun

Answer 8

Then we would have no more sunlight; life on Earth would die.

Answer 9

you die
