black hole的英文解释
lack hole:
An area of space-time with a quantum singularity at its center.The singularity has a theoretically infinite mass,making it impossible for even light to escape.Around the singularity is an Event-Horizon.This is also known as the point of no return because it is the critical area that light can no longer escape from,and time itself comes to an end,or is at the same time ad-infinitum.Much work has been done on this subject by Stephen Hawking.
