no, the center of a black hole is said to be of infinite density, thus, infinite gravity. no star has infinite gravityYes.
Gravity is caused by mass, and the ammount of mass in the black hole is the same as the ammount of mass of the sun that created it.
However, a black hole is much smaller then a star, so it's possible to get closer to the center then it was with the sun.No, the mass of the black hole is about equal to the star, not the gravity. But if the sun gets smaller, but maintains its mass, its gravity will increase. Our sun is 1,400,000 km across, and a black hole is no bigger than the period at the end of this sentence. So a massive increase in its gravity while maintaining its mass.The star that existed before it collapsed into a black hole, emitted light, correct? The Black Hole (from the very beginning of its existence) has gravity so intense that even light cannot escape.
You do the math.
.gravity is controlled by the mass of the object. so if you have a 10 solar mass star collapsing into a black hole and we will assume that all of the star's mass is going into the black hole.
(maybe i should clarify that the star is collapsing to form the black hole, not falling into an already existing black hole)
if the end result has the same mass as it had at the beginning. then yes the black hole's gravity would be the same as the stars had been.
if you took our sun away and replaced it with a black hole of equal mass nothing would change. we would not suddenly get sucked into it, nor would any of our orbits even shift. we would get no light from it obviously but in terms of gravity things would stay the same.
hope this answers you, if i'm not clear about something just send me a message.No. When a star forms a black hole, it usually blows away a lot of its own mass in the process, so the resulting black hole actually has less mass than the original star. That said, if you had a star and a black hole both of equal mass, the gravity on the surface of the star and the gravity at the same distance away from the black hole would be just about the same. For example, the Sun has a radius of about 695500 kilometers. If you had a black hole with the same mass as the Sun, the gravitational acceleration 695500 kilometers away from it would be about the same as that on the surface of the Sun, because the distance from the center is the same. However, the similarities end there. As you get farther into the Sun from the surface the gravity may become slightly more, but will eventually tend to become less and will be zero right at the center of the Sun. On the other hand, as you get farther in towards a black hole, the gravity becomes higher, and higher, and HIGHER, with virtually no upper limit (or in any case, you would be torn to pieces by tidal effects and then crushed into degenerate matter long before you reached the limit, and the limit would furthermore be constantly increasing). This is why even a relatively small black hole can suck in light while a large star cannot.From far away, the gravitational force of a black hole is equal to that of the star that created it. If a star collapses radially into a black hole, there is no effect on the curvature of space outside the original radius of the star.yes, but it quickly rises due to the matter it is absorbing.#If you have any other info about this subject , Please add it free.# |
