Are Black Holes and Nutron Stars the same thing?

Question

I keep reading that they're both collapsed stars - but are they two differing catagories of the same event, or the same thing?

Answer 1

A Neutron star is in the phase before the black hole where the density is much less than that of a black hole where it is infinite. Neutron stars can have escape velocities and no event horizon. A neutron star is also a star with a density of 8×1013 to 2×1015 g/cm³ instead of infinite.

Answer 2

No Neutron Stars are not the same as a black hole. Black Holes are so dense that their gravitational force is too strong for light to escape. Where as Neutron stars have a large mass, but can still be measured by instrumentation. Neutron stars are still a star, but with little energy on the surface and have a small surface area. The escape velocity from a Neutron stars is around 1/2 the speed of light (150,000 km/s), which although strong, is no where near that of a black hole.

Answer 3

Black holes and neutron stars are quite different although they are both collapsed stars. A neutron star has sufficient mass and gravitational attraction that all atoms and molecules in it or attracted to it degenerate into a solid body of neutrons. A black hole is even more massive with stronger gravitational attraction such that the matter in it or attracted to it degenerates into a "singularity" (perhaps as small as a period on this page) for which the common laws of physics likely do not apply.

Answer 4

What happens to a star at the end of its life depends on it's mass. The very massive stars become neutron stars which are very dense and have a very strong gravity. They can be seen and most of them spin very fast emiting electromagnetic radiation and are known as pulsars. Black Holes come from even more massive stars, their density is even greater and their gravity is so great that they don't even let light escape. Knowledge of their existence is based on theory and the viewed effects of their gravity on other objects.

Answer 5

No, Neutron star is a collapsed star but still gives off light. A back hole is a much larger star that has collpapsed and it's gravity is so strong that not even light can escape.

Answer 6

No,they're a bit different.A black hole is a collapsed star that has a tremendous gravitational pull and doesn't let anything get away.Not even light.Neutron stars ,on the other hand,are pulsars.So they aren't even near the same thing as black holes.What kind of astronomy books are you reading ,anyway?

Answer 7

No, they are not the same thing. Though, they are both collapsed, I believe that blackhole's are very different. For one thing, the nutron star doesn't have near the amount of immense gravity.

Answer 8

Black holes are much denser than neutron stars.
From what I heard, if you get a teaspoon of matter from a neutron star, it would weight as much as a skyscraper or something.
If you get a teaspoon of matter from a black hole, though, it would implode the planet from its sheer mass.

Answer 9

nope, very different. (stars for one thing emit radiation (in on form or another)) black holes not so much (they actually cannot be seen and the only way we even know they are there is because nothing else is.) yes we actually don't know if a black hole is real. its just that nothing else is in that place so we assume a black hole is there.

Answer 10

No, they are not same at all.
