Why Neutron Stars May Hide a New State of Matter

What happens to matter when you crush it beyond atoms, beyond nuclei, beyond anything a laboratory can recreate? Deep inside neutron stars, dead stars no wider than a city yet heavier than our sun, matter reaches densities so extreme that the rules of nuclear physics begin to fail. Protons and neutrons lose their identity. Quarks may roam free. Entirely new phases of matter, never seen anywhere else in the universe, may be hiding in these cores. And our most powerful theory of the strong force, quantum chromodynamics, cannot tell us exactly what is down there, not because the theory is wrong, but because the mathematics is too hard to solve.
In this video, we explore the full journey from ordinary atoms to the most extreme compression in the cosmos. We break down why nuclear physics fails at these densities, what exotic phases, from hyperons to quark matter to color superconductivity, physicists have proposed, and how observations of neutron star masses, radii, gravitational waves, and cooling rates are finally beginning to narrow down the answer to one of the deepest open questions in all of physics.

I don’t know what’s up there, but ancient history and technology is a very interesting subject. Vimanas, aka UFOs UAPs have been around for a very long time and when you read the Bible and the book of Enoch, it explains all of this. Every ancient civilization had “gods” that came down with tech and claimed human sacrifice, mostly babies, and started wars.
I believe the Biblical account personally, because YHVH demanded a stop to child sacrifice and human sacrifice. No Jesus wasn’t a human sacrifice. He lay down his life.
Anyway, today we have all this fancy tech and people are demanding to destroy pre-born humans. Abortion was first talked about in Enoch. So same MO different era.
