Black holes are astronomical objects that have such strong gravity, not even light can escape. Neutron stars are dead stars that are incredibly dense. … Both objects are cosmological monsters, but black holes are considerably more massive than neutron stars.29 Jun 2021
In Space a black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
So in our region of the Universe, there are some 100 billion supermassive black holes. The nearest one resides in the center of our Milky Way galaxy, 28 thousand lightyears away. The most distant we know of lives in a quasar galaxy billions of lightyears away.
A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are astonishingly heavy, with masses ranging from millions to billions of solar masses.
This phenomenon is thought to be the final fate of the more massive stars (see black hole). The Schwarzschild radius (Rg) of an object of mass M is given by the following formula, in which G is the universal gravitational constant and c is the speed of light: Rg = 2GM/c2.Dec 15, 2021
At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity. Just what the physics is like at this point in the black hole no-one can say for sure.Aug 13, 2020
Of course, no matter what type of black hole you fall into, you’re ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you’re done. There’s no getting out.Jul 28, 2020.

A neutron star is the collapsed core of a massive supergiant star, which had a total mass of between 10 and 25 solar masses, possibly more if the star was especially metal-rich. Except for black holes, and some hypothetical objects, neutron stars are the smallest and densest currently known class of stellar objects.
Neutron stars are typically about 20 km (12 miles) in diameter. Their masses range between 1.18 and 1.97 times that of the Sun, but most are 1.35 times that of the Sun.
Types Of Neutron Stars
Soft gamma-ray repeater (SGR)
Anomalous X-ray pulsar (AXP)
Low-mass X-ray binaries (LMXB)
Intermediate-mass X-ray binaries (IMXB)
High-mass X-ray binaries (HMXB) etc
Neutron stars are formed when a massive star runs out of fuel and collapses. … (Stars with higher masses will continue to collapse into stellar-mass black holes.) This collapse leaves behind the most dense object known – an object with the mass of a sun squished down to the size of a city.
about 1.4 solar masses
Neutron stars have a radius on the order of 10 kilometres (6 mi) and a mass of about 1.4 solar masses. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei.
Whats the difference between a neutron star and black hole?
A neutron star is the remnant of a star whose mass ranges from 1-3 solar masses. A black hole is the remnant in case the star mass is greater than 3 solar masses.
