I'm wondering if a ship orbited a black hole for a year, how large would the black hole be for it to equal 10,000 years on earth?

Gravity is a fundamental force of nature that describes the attraction between two objects with mass. It is responsible for keeping objects, such as planets, in orbit around a larger body, such as a star.
Time dilation is a phenomenon in which time appears to pass at different rates for objects in different gravitational fields or moving at different speeds. It is a result of the curvature of spacetime, as described by Einstein's theory of general relativity.
Gravity and time dilation are closely related because gravity is a result of the curvature of spacetime, and time dilation is a consequence of this curvature. Objects with more mass, such as planets and black holes, have a stronger gravitational pull and therefore experience more extreme time dilation effects.
A black hole is a region of spacetime where the gravitational pull is so strong that nothing, including light, can escape its grasp. It is formed when a massive star dies and collapses under its own gravity, creating a singularity, a point of infinite density and zero volume.
No, nothing can escape from a black hole, not even light. The intense gravitational pull of a black hole is so strong that it traps everything within its event horizon, the point of no return. However, some theoretical models suggest that particles can escape through quantum effects, but this has yet to be proven.
