How come the gravity of a stellar- mass black hole is strong enough to trap light but the gravity of a stellar-mass star (eg the sun) is not strong enough to trap light ?
It means that the gravitational field is stronger at the surface of the smaller object, because the surface is closer to the center.Tatest said:Doesn't that mean that the smaller object has stronger gravity ?
The main difference between a black hole and a star is that a star is a massive ball of gas that produces light and heat through nuclear fusion, while a black hole is a region of space with such a strong gravitational pull that nothing, including light, can escape from it.
The gravitational force of a black hole is much stronger than that of a star. This is because a black hole is a concentration of matter with an extremely high density, while a star has a less dense and spread out mass.
Yes, a star can turn into a black hole once it runs out of fuel for nuclear fusion. When this happens, the star will collapse under its own gravity, causing its core to become infinitely dense and creating a black hole.
Black holes and stars have a significant impact on the space around them through their gravitational pull. However, the effects are much more pronounced with black holes due to their stronger gravitational force.
Yes, there are different types of black holes and stars. Black holes can be classified as stellar, intermediate, or supermassive, depending on their mass. Stars can also be classified based on their size, temperature, and composition, with categories such as red giants, white dwarfs, and neutron stars.
