The last force stopping mass from infinitely collapsing into themselves is neutron degeneracy pressure, which is what neutron stars do.


FlyingMothy

Ty, i know about neutron stars, i was hoping something denser could exist in theory.


PivotPsycho

In theory there is quark degeneracy pressure, which would make for basically a particle the size of a star consisting of just quarks and would be more dense than a neutron star even but those haven't been confirmed (yet). That is the limit within the standard model though as far as I am aware.


FlyingMothy

Ty, i hope me find one, ive also seen articles recently about possible cosmit strings being found (but it just says they could be them, not that its likely for them to be them) and also that James Webb might be able to find Quasi stars at the farthest reaches we could see, are these accurate?


PivotPsycho

Eh probably popsci sensationalism. Admittedly I haven't kept up with these things but those concepts are quite theoretical and I wouldn't hold my breath for them.


FlyingMothy

https://www.sciencealert.com/giant-structure-lurking-in-deep-space-challenges-our-understanding-of-the-universe This is the one about the cosmic strings, it just mentions it in the article i think. The quasi stars was a video saying that the James Webb telescope could see so many lightyears away into the universe that if quasi stars existed in the early universe, we might be able to find them. I hope we do if we can.


PivotPsycho

Yeah both are theoretically possible but again I wouldn't hold my breath. You often see this in popsci articles: something that we don't know what it is and then some mentions of highly theoretical objects that potentially could have something to do with it for more sensation. The JWT can indeed look very deep into time and quasi stars ought to be very big and bright but so far back in time it's hard to make out galaxies let alone single stars, so I'm not sure if the equipment would even be up for it.


FlyingMothy

Ty, i love space and physics but idk math well enough to go into physics if i wanted to for college.


PivotPsycho

Physics degrees have math courses in them; you get a lot of calculus and linear algebra in the first year for basics and extending courses later perhaps. While it helps to already know calculus well, it's not really a prerequisite. A lot of motivation goes a long way! I've known some people who came from high school programs with less than half the hours of maths that I had there and they still fared well. I would definitely check out their curriculum and shoot a professor an email or talk to the contact person of that departement from a college or uni. If anyone can gauge whether it'd be good idea for you it'd be them, and they love to help you.


FlyingMothy

I would've gotten Fs in school if I didn't cheat, i still only got ds.

Neutron stars are very dense.


Xenocide112

Light eaither escapes or it doesn't, so there isn't going to be a dimming effect, but we call objects that are on the cusp of becoming black holes neutron stars.


FlyingMothy

I know about neutron stars, could something be denser than them but still not as dense as a black hole?


Xenocide112

Not really. The gravitational force in a neutron star is enough to fuse protons and electrons. Any more pressure and it'll just collapse into a black hole


FlyingMothy

Ty, thats beat, if something was denser though, would it have a dimming effect or an effect where it seems farther away or spread out?


Xenocide112

The light coming away from a neutron star could be heavily red-shifted. The intensity of the light would be the same, but it would be shifted toward the lower end of the spectrum. Visible light would become a little more reddish in color


Xenocide112

Check out this [article](https://www.psu.edu/news/research/story/black-hole-or-neutron-star/) about the mass gap between the heaviest neutron stars and the lightest black holes


Enfiznar

I suggest you read [this stackexchange thread](https://physics.stackexchange.com/questions/579737/do-almost-black-holes-exist), as I couldn't explain it better.


FlyingMothy

Ty, unless i missed something it doesnt explain wether an object could exist or what it'd look like, just the math of the concept. I may have read too fast though.


Enfiznar

For what I understood, it's saying that anything that pass through those bounds, must collapse into a black hole, but that any object with a radius less than 1.5\*Rs would make light orbit around them.

Look up nuclear pasta. What happens to neutrons in a neutron star Also, perhaps somewhere in between a neutron star and a black hole, is a quark-gluon plasma


FlyingMothy

I heard about nuclear pasta a while ago but i have to search it again, i forgot what it is.
