A:
How likely is it for a black hole to collide with Earth? Would we have much warning?
In space-time curvature, black holes are the region where the gravity is so strong that nothing even electromagnetic waves (light waves) can escape through it.
The boundary of no escape for the black hole is known as the event horizon.

- Why are gravitational waves hard to detect and is there a way to simplify the process? How?What is the orbital period of a bit of matter in an accretion disk 2 x105 km from a 10-solar-mass black hole?(Astronomy) Schwarzschild Radius. Part A: Find the Schwarzschild radius for the least massive black hole. Part B: Is your calculated value greater than, the same as, or smaller than the diameter of a typical neutron star and the diameter of Manhattan, New York, which is around 10.9 km?
- You discover by dropping particles into it that the Event Horizon (Schwartzschild Radius) of a black hole is 171 km. How massive is it? (enter just the number in solar masses)Why are gravitational waves so difficult to detect?If we view events occurring on a star that is collapsing to become a black hole, do we see time speeded up or slowed down?

- A spaceship is located around 2.6×10¹³ km from the black hole Messier 87. It has a mass of 6.6 billion suns. How long will their day last compared to a day on Earth?Assume a neutron star has a mass of about 1.2 times the mass of the Sun and a radius of 7 kilometers. If the escape speed is V2esc=2GM/R, work out the formula for the radius of the Event Horizon around a Black Hole of mass M.I understand that to an outside observer, the light from a star that is collapsing into a black hole will become more and more red-shifted as the surface of the star appears to approach the black hole event horizon. The outside observer will never actually see the surface of the star cross the black hole event horizon. This applies to all outside observers: at infinity, in orbit around the star/black hole or those using a rocket to hover above the black hole. Conversely, I know that for someone on the surface of the star that is collapsing to form a black hole it will appear quite different. The observer on the surface will not see anything unusual happen as they cross the event horizon and in a finite time they will reach the singularity at the center of the black hole where we do not know what will happen since general relativity breaks down in a singularity. So, now consider an observer that starts at a great distance from the star who is continually falling directly into the star…
