Supermassive black hole. 2.A direct image of the material in the accretion disk around a black hole. The time dilation of a stationary clock at radius r from the center of a Schwarzschild black hole (relative to another clock infinitely far away) is exactly the same as that of a clock moving in flat spacetime with speed v where v is the escape velocity of the first clock parked outside the black hole. But how does that happen?

In this case the answer is …

There isn't necessarily any material surface there.But if the escape velocity is $c$, why can't light escape?It can if it comes from a place just above the horizon. “A black hole just sits there, passively.

greater than the speed of light. Another form that stars can transform at the end of their lives is a black hole.

Discuss the workings and policies of this site It only takes a minute to sign up.The escape velocity of Earth is $v=\sqrt{\frac {2GM}{R}}$, where $M$ is the mass of the Earth and $R$ it's radius (approximating it as a sphere), and is much less than light speed $c$.But I want to know the escape velocity of black holes. FOREWORD: Cosmologists always claim that their black holes, mathematical fabrications entire, have an escape velocity.

As a result, the star neither expands nor contracts. It's about 11.2 km/s at the surface. The formula I wrote assumes you measure the distance from a point at infinity, which is not the same since speed is coordinate dependent.Where the "surface" is the event horizon.

I would presume the space between would be mostly empty. One possibility is that they’re the result of mergers between star-size black holes.No one knows exactly what lies within a black hole’s event horizon. Earth’s escape velocity is about seven miles per second, or about 25,000 miles an hour. A supermassive black hole (SMBH) is the largest type of black hole, though there are few official criteria on how such an object is considered so, on the order of hundreds of thousands to billions of solar masses.

3.Detection of gravitational waves from mergers of black holes in binary systems. The diameter of the "black hole" would be where the escape velocity exceeds C, which would be mass dependent. The simplest definition of a black hole is an object that is so dense that not even light can escape its surface. The escape velocity for material inside a black hole is. What is the likely final fate of a star of 30 solar masses when it is on the main sequence? how far from the black hole does the escape velocity become equal to the speed of light. But when a star’s fuel supply is exhausted and the outward pressure stops, gravity causes the star to shrink.What happens next depends on the size of the star. The After coming back to this question, your answer is valid for a Schwarzschild BH when the escaping particle travels radially and you measuring the speed from the starting point. Black Hole Escape Velocity – a Case Study in the Decay of Physics and Astronomy. That would still quite simply imply infinite energy, so it seems consistent.I don't buy your derivation. Things can fall onto it, just as meteors can fall to Earth, but it doesn’t pull stuff in.”The force of gravity governs the motion of planets, stars and galaxies, and it’s responsible for creating black holes, too.Stars shine because of the nuclear fusion reactions taking place in their cores.

The concept of a black hole can be understood by thinking about how fast something needs to move to escape the gravity of another object – this is called the escape velocity. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under A _________ happens when a single high mass star explodesA _________ happens when a white dwarf in a binary system accumulates more mass than Chandrasekhar limitthis event recurs and happens when one of the companions in the binary system is a white dwarf_________ are hot, compact remnant stars whose mass is typically between one and several times that of the Sun, but their size is only 10 km or lessthis recurring event happens in the case of a binary system in which one of the companions is a neutron starwhich of the following is a remnant of a dying star?if stars rotate with periods of tens of days, why does a neutron star rotate several to thousands of times a second?C.

extremely rapid rotation and a strong magnetic fieldwhat is the escape velocity at the event horizon of a black hole?which of the following can actually escape a black hole?

If it’s about the mass of our sun or a bit bigger, it will collapse until it’s a roughly Earth-size body known as a Why can’t anything escape from a black hole?

If you mean from the center of a black hole at which the radius is 0 then the escape velocity is infinite by basic math.

c. larger than the speed of light.

Into a Black Hole.

The Event Horizon is the last distance from which light can escape the pull of the black hole.
