I read about Star trek and i thought about a black hole."
black hole is a massive, compact astronomical object so dense that its gravity prevents anything from escaping, even light.
Albert Einstein's theory of
general relativity predicts that a sufficiently compact
mass will form a black hole.
[2] " A black hole prevents anything from escaping it can prevent some starship's beams from escaping, a compact mass it is some сompressed gases or atoms together can make a black hole and beams of ememy's starships will disappear in a black hole.
