What is the state of matter present inside a neutron star?

Massive neutron stars (NS) are expected to possess a quark core. Neutrons according to quark theory will have compatly packed neutrons that contains two down quarks with charge −​1⁄3e and one up quark with charge +2⁄3e neutralize inside the particle, whereby repulsion does not exist between 2 neutrons. Compressing Protons beyond 0.7 femo meters trigger nuclear explosion whereas 2 neutrons, however, Neutron stars are usually observed to pulse radio waves and other electromagnetic radiation, and neutron stars observed with pulses are called pulsars.

Neutron stars are believed to have formed by the gravitational collapse of the remnant of a massive star after a supernova explosion, typically 30 km small radius with very high density, predominantly composedof closely packed neutrons. These stars have insufficient mass to become a black hole. At an average stars having 400% the mass of ours will go supernova, and its central region will collapse down past the stage of atoms, collapsing down to a core of pure neutrons! At masses beyond that, even the neutrons succumb to the force of gravity, and get compressed down to a size so small that light cannot escape from it. At that stage, we've progressed from a neutron star to a black hole!

Even as the most massive stars die, they don't just die in a supernova explosion but the star's core also collapses, leaving either a neutron star or a black hole behind! A cutoff between a neutron star and a black hole lies - whether it's 2.5 or 2.7 or 3.0 or 3.2 solar masses or minimum 28-30 km radio are however disputed-when two neutron stars collide, (probable once every 10,000-to-100,000 years or so in a galaxy) even if their individual mass wouldn't have quite crossed the form-a-black-hole threshold on their own, the resultant process could create a black hole below the form-from-a-supernova mass.

A new form of matter called nuclear pasta is found inside neutron stars. In the core of the nucleus the atoms are compressed in a confined space and it forms a shape of a pasta and that is why it was termed so. Hope you understood.

The matter is baryonic in nature yes, but the protons and electrons are crushed to form neutrons. So much so that even the spaces between the nuclei gets crushed. Giving rise to a new form of matter which is oddly known as nuclear pasta.

"Nuclear Pasta... A very rare state of matter (so far only found in Neutron star).

In this state, nuclei of atoms get so tightly that they arrange themselves in patterns that looks like pasta..

Long time Vietnamese-expatriate here. Just moved back to the country. Any advice?

Welcome back home! brotherA foreigner is one of your advantages when you are in Vietnam! You are confused with the current situation in Vietnam, you just live there! Do not care much!You will feel that, it's hard to put into words ...! If you are

Have you ever gone hammock camping? How does it differ from other camping experiences?

When the weather allows it, it's fantastic. Less weight to carry and way more comfortable in my opinion. Of course, unless you have a screen, bugs could be an issue so you do need to be more diligent with bug spray.
