if you assume there's always been some space with very basic particles floating about in it for a infinite amount of time surely something that's always existed would be incredibly advance by now, all the matter in the universe is destined to decay into nothingness in the future the universe is difficult to understand, maybe there's always been some space with very basic particles floating about but because of the way the universe works all matter end up in a black hole the cycle repeats maybe
Yeah- that's a very good point! Surely we would have evolved into something better by now! I think it's just that my brain just won't wrap itself around 'nothing'. Like- I feel like just space for stuff to form in feels like it should have always been there. But then- my head won't wrap itself around space either! Is it really infinite? Or- does it have an edge? If so- what's outside of it? It almost feels as stupid as thinking the earth is flat and we could slip off the edge! But then- it's still the same problem I suppose- how does something form out of nothing in space?
God yeah- black holes- weird. I find it illogically sad that a star can die! Can't quite get my head around it. So- they collapse when their cores run out of hydrogen right? Supposedly under their own gravitational pull. But- aren't they made of gas? Just how dense can they be- to start a black hole? It just seems so weird. I guess they could be really big! I still don't get it but then- I was crap at physics. But- if it's a really BIG star- then- even if it's gas, it still produces gravity. Supposedly it's mass produces that. Plus, it wouldn't collapse without it presumably- but then- if it does collapse- doesn't it just become much smaller? Why then would it suddenly exert so much more gravity? I guess because it's more dense. So, a small dense solid can create more gravitational pull than an enormous ball of gas?
They scare me to be honest! But yeah- that makes sense- black holes perhaps create universes out of all the stuff they suck in. That would be kind of nicer for them really- I feel like they've gotten a rather sinister reputation. Still- if more life pops out of them- my opinion of them hasn't warmed up much!
