It's absurd to assume that nuclear weapons are a part of reality without humans for example. The physical or natural realm is what it is without humans regardless, what we do is manipulate and configure things in order for us to further our understanding of what actually is.

nuclear weapons? As in, uncontrolled fusion and fission reactions?

You understand the sun is a gigantic fusion ball, right?

And there is evidence of a naturally occurring fission reactor, I think it was in Africa.

So the origin of the sun is the automatic question one must answer then.

Research indicates it's from the accretion of a first gen star super nova.

Aren't suns naturally occuring fusion

Yes.

That's what I just said.

So how do super novas form

Your ignorance of physics does not mean things do not exist.

the death of stars

I never claimed anything didn't exist

A super nova is the result of a sufficiently massive star using up it's fuel.

Until the outward pressure sufficiently exceeds the force of gravity required to keep it together.

So why would it do something like that?

How many time through human history has our understand of the universe changed

It's not a why, it's a how.

I wonder when the next massive change will occur

It has to do that because the gravity becomes stronger

How can we know?

the gravity causes the star to collapse

There is no evidence to indicate anything beyond random.

Why bother knowing if it just is regardless of our understanding of physics

To better our understanding of the universe by testing our intellects against those same secrets.

Isn't the universe expanding at such a rate that future humans will have no exvidence of the big bang?

If it exists and humans aren't real then does it exist still? What does it become then?

That was the theory, I understand that theory is now being challenged.

That's what we currently understand about the rate of expansion

We think it's dark energy

We are literally running out of fuel just like a star.

No, we're not.

I always thought it was cool that the static on old tvs was left over energy from the big bang

We can refuel lol

Not any time soon

interesting way to explain it

How are we not

We have a star.

It has literally millions of years of life ahead of it.

We are. Doesn't the universe on have so much hydrogen to fuse

That doesn't mean things dont die
