We are screwed when star explodes. How ever far we run it catches us, calculus dictates. Speed of light proofs it. Settle on mars, in vain. 2hwvg

Not if we live underground or underwater.
Hydrogen is great at blocking radiation so underwater would be the best option.

That water is going to have to be on Europa or somewhere else that far out, earth is going to get burned to crisp if not swallowed altogether

Thats like billions of years to fuck off to a younger star on a generation ship anon, light energy falls off by inverse square so you will be fine, i dont think sol is ment to nova anyway

We've been around for a very short time. Do you really believe we will still be here when it happens?

Wrong.
A supernova explosion nearby will roast the surface but the enormous neutrino flux will also bake the insides of the planet. And you cannot shield against them.

Uhm no
You could probably throw all the neutrinos in the universe against a single person and literally nothing would happen

4.5% of a reactor's energy is lost as neutrinos. There is an enormous flux at any time, filling the entire universe. If you directed that through one person he would be vapourised instantly.

However big you think supernovae are, they're bigger than that.

You have to be as close as Jupiter is to the Sun to a supernova to have the neutrinos affect you like that. More likely, it would be one within a few light-years away that would roast the ozone layer but the Earth would recover albeit slowly.

We'll either be long extinct or spread across multiple star systems by then. No point in panicking about it.

I thought starts. when imploding, emits a lot of radiation aligned with the rotational axis. I guess if we are looking down that barrel when it blows, we could be affected, even at a great distance.
