What happens when matter can’t get any denser yet somehow does? The answer - it becomes “strange.” Strange Stars may be the most massive stellar remnant that is just shy of forming a black hole. And they could be even cooler than black holes.

Neutron stars are made of a substance known as Neutronium. It was thought that this was the densest form of matter possible but some theoretical physicists believe that at the core of some neutron stars the Neutronium breaks down even further, into quark matter. It may even evolve one step further into “strange matter", the densest and most stable substance in the universe.

Would strange stars react with the electroweak force? Could that be what dark matter is made up of? Strange quarks?

Can someone ELI5: If protons consist of 2 up quarks & 1 down quark, & electrons aren’t made of quarks at all, then how does mashing electrons & protons together produce a mass of neutrons (which consist of 2 down quarks & 1 up quark)? Growing up I didn’t know much about quarks, so it seemed intuitive- electrons are negatively charged, protons are positively charged, so compress them together & you get a neutral charge... But thinking about it on the level of quarks & electrons it seems harder to wrap my head around.

Well, if there are strange stars, why not charmed stars? And top/bottom stars? Is there a sweet spot in mass that could allow that without collapsing into a black hole?

Lets be honest here. Neutron stars are just failed black holes.

So what would black holes be made of? They must be squished even further then quarks in strange stars.
Supersonic Tumbleweed
Cool. Add the remaining difference in mass and get a perfect black hole on demand! With minimal mass possible! Very convenient. Imagine sending a probe into a strange star and accidentally causing it to further it's collapse. Someone's going to be fired lol

it makes perfect sense that more mass and more gravity forces neutrons into their constituent parts. quark stars would be the last phase before singularity, unless there is something smaller than quarks and their associated sub-atomic particles. eventually youll squish stuff down with enough mass to turn back into an all energy no matter state like the time at the beginning of this universe.

How can down quarks convert to strange quarks? Aren’t they elementary particles? Doesn’t such a conversion indicator that they aren’t elementary particles and have internal structures? Is it possible that quarks are composed of gluons and that gluons are more than just a force carrying particles, and under these extreme conditions the gluons are packed together at near plank length density. Perhaps the core of a strange star is the proposed gluball?

I really would apreciate if , for once, things like ‚thin crust‘ woul be quantified. In astronomy, things are often relative, and neutron stars are especially weird. So: how thin is ‚thin‘? A few mm? A few m? A few kilometers? Just a general hint at the order of magnitude would be neat

What about when you mention taking measurement or stars and galaxy drift. Are you aware you didn't mention that 2 billion light years away is in the past. And the current position needs to be worked out? Because that's what i heard you not say. But you know better. I am sure of it.

would a neutron star collapse into a black hole, if you could slow down their spin?! isnt that the only force stopping their collapse? or are there "slow" or not rotating neutron stars out there, or even possible?!

It bugs the sh** out of me that people refer to black holes into which things fall. A black hole is anything whose escape velocity is greater than the speed of light. It's not a hole into which things fall. Also, I've never seen a video talking about hawking radiation causing a black hole to revert either. If you had a black hole whose escape velocity was just barely greater than C and hawking radiation caused the black hole to slowly lose mass, then eventually, the escape velocity would be less than C and the black hole should revert. The basic laws of Physics dictate that information can't disappear from the universe so that implies that blacks holes can't be infinitely dense with infinitely small size which in turn implies that a black hole has a surface, albeit a surface within the event horizon.

"Dark energy is real" In the sense that physicists still do not understand what it is that is causing the universe to expand at an accelerative rate and have named this gap in their knowledge "dark energy", you are completely correct!

Not really. The mass of electrons, neutrinos, etc. in the sun would be not inconsiderable. A tiny fraction of course but not negligible.

This question probably isn't addressed in this article, but perhaps can be in another. Crab's pulsar rotates around 30 rps I believe. Is that, then, the frequency of the RF? If not, then what is and how is it generated?

just wandering, hypothetically, if there are 3 infinite things, and you were to randomly select from them, which one would be selected? each of them are infinitely larger than the others meaning there would constantly be infinitely more of a chance for one out of the three to be selected. In this scenario, would you just give up and assume that they are all equally infinite, thus making them all just as likely, or would you instead keep chasing the fact that each is infinitely more likely than the last?

I'm going to go out on a limb here and hope someone corrects me if I'm wrong. A neutron is merely a proton that has absorbed an electron. The masses add up as far as I can tell and the charges do, too.

A pulsar (from pulse and -ar as in quasar)[1] is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles.
