Will humans end up like Kryptonian?

Lets just hope that if our sun goes super nova,we get blew away or something like that and survive.

Humanity (Or other species that have replaced humanity) have probably invented space technology enough to travel on other planets where we can live.

Our sun won't go supernova! Everyone knows it's too small 🤨

Thank you!Finally someone agrees with me!

Pfft...kids, kids...Our sun too small to go nova? Well, if the 'everybody' you're talking about that knows it's too small are all eight year olds then well fine. But ask anyone who knows anything about astronomy, they'll tell you that any star is capable of going nova. Do you even know how large Sol is? For that matter, do you know what Sol is? (if you don't, you shouldn't even be discussing this). It's roughly 1,390,000 kilometers in diameter. And a single solar flare which erupts from the surface of the sun generates more power than tens of millions of atomic bombs, and a solar flare isn't even a quarter of the size of the entire sun. Now, just what do you think happens when a star dies? It doesn't just fizzle out like a candle. It releases tremendous amounts of energy, equivilant of millions of solar flares, each with more energy than ten million atomic bombs. Our sun may be too young to go nova right just yet, but saying it's too small to go nova is about as ignorant a comment as I've ever heard.

The sun doesn't have enough mass to form the supernova explosion when it is a red giant its outer layers will just disperse. There is an equation in astonomical physics which demonstrates this. The Sun would require something like 1.4...etc X its mass to go Nova and become a neutron star and 3X its mass to go nova and become a black hole.

Certainly 😛

Scientists aren't always accurate so you can't really believe this as a fact.

If it doesn't expand so as to consume Earth, the sun in its giant phase will certainly render the planet uninhabitable (if that hasn't already occured).

Well, nova, solar expansion or the sun simply becomes a black dwarf- the end result will be, that the earth will be destroyed or turn into a lifeless wasteland. I'm still pretty certain we'll do ourselves in before any stellar events take us out.

And technically, if our sun does expand to the proportions of a red giant, it could go nova.

Oh, okay.

Our sun cannot possible go nova, it is too small and therefore too stable.

In reality stars which are large enough to go nova would not support the development of Earthlike worlds in their systems because their stella life spans are too short.

You're absolutely right shaber. Just did some fact checking. Something I should have done before obviously before shooting my mouth off.

I don't think that our sun will go super nova or grow any larger.

As I've said before,scientists are always accurate.

That's not necesarily true.

If the Sun pulled in enough additional matter, it could collapse under it's own gravity become a white dwarf, and if it achieves critical mass, BOOM. Supernova.

If the Sun was going to become a supernova, the Earth would be pulled into it millions of years before it reached critical mass.

Like Krypton.Well,lets hope scientists won't be foolish and don't build rockets so we can espace.But in a billion years we'll probably be living on other planets anyway.

And you guys have been saying IF the sun goes supernova.There is no gurantee that this will happen.Let's hope that it doesn't.
