After the new Kurzgesagt video about black holes...

“Yeah, I’m really getting into non-black-hole stellar mass singularities at the moment. You’ve probably never heard of it.”
Isn't the whole thing about gravastars that they don't have singularities?
Imma wait to be excited about this, it's some kinda nonsense like gigantic atoms, with a hard candy shell made of bubbles but the energy of 10 suns idk man that's pretty out there
Ofc existence is pretty strange on a good day ...
Well, black holes are pretty out there, too. Singularities don't really make sense with our current understanding of physics. Also we can directly observe some really weird states of matter like bose einstein condensates, so I don't think this is ridiculous.
My mang if giant atoms exist then we are definitely the empty space between them, part of a large X-dimensional furry
With the number of 'impossible' things I'm seeing each day in the news, this video was met with an optimistic shrug and a bottle of wine before work.
I mean physics is insane in general. XKCD had a video the other day that mentioned that if you had enough light/a strong enough laser, space itself stops being transparent because matter suddenly starts materialising out of nothing and blocks the light.
I watched it last night. I'm still trying to get my head around positive pressure vacuum.
Wikipedia says "the inner region has thermodynamically no entropy and may be thought of as a gravitational Bose–Einstein condensate" if that helps
Oh thanks, that clears it up completely.
It helps in that I clearly don't understand what is happening, but at least I can put fancy words with it.
Can you get your head around singularities? Because as much as I do understand, I still don't understand them.
Its just a part in the equation where you're dividing by zero, that's all. We know you cant divide by zero, so it means our theories are incomplete.
The gravastar theory is notable (IMO) because it does away with the singularity. Although, it seems like this theory is borderline unfalsifiable, since any way you could detect a gravastar would also be insistinguishable from a black hole.
Personally, I am of the (completely unsubstantiated) opinion that black holes create universes (somehow) because it is a simple, succinct answer to many questions. So, any theory that takes that seriously would be worth further research, imo. But until there is some kind of observational evidence, I think this is just relegated to the realm of "that's a neat thing that math can do".
I'm gonna rephrase that for both of us, I think (hope):
We understand better what it is we don't understand about them.
What's weird is I do! After decades of watching and learning I think we're a 3-dimensional species that can only mathematically measure things via 2-dimensional thinking. (We can only visualize space-time in a single plane for example mentally, honestly)
All the things that 'disappear into nothing' like singularities and even UFO's I think simply are 4th dimensional in nature if not higher. They dip in and out of what we can perceive and the beings that live there are amused at us crawling around like ants in an ant-hill.
I wonder how old these three people are now ...

The source image was from 2015, and the people appear to be in their mid-20s then, soooo.... about 35 now.
Huh.
Gravastar are sexy but Black hole can suck better.
You know I got super high a few weeks ago and imagined something similar to this so I'm pretty sure they're on to something here.
The soundtrack on this video was a banger too

Ohno. My brain can't take this rn. Thanks though
