how do scientists know black holes exist in space if they do not emit light? use details to support your answer.

Explanation:

Scientists infer black holes' existence through their gravitational effects. For example, they observe the motion of stars around an invisible mass (indicating a black hole's gravity). Also, when matter spirals into a black hole, it heats up and emits X - rays (accretion disks). Gravitational lensing (bending of light by a black hole's gravity) is another indicator.

Answer:

Scientists know black holes exist through gravitational effects (e.g., star motion around invisible mass), X - ray emissions from accretion disks, and gravitational lensing.
