Thanks for sharing the great excitement. Three concepts worth further elaboration
1. Event horizon — the boundary where even light can’t escape gravity of a black hole
2. Constellation — a certain geometric shape formed by a group of visible stars.
3. Galaxy — a gravitational bound system of stars
Question, which one of these three concepts is not a scientific concept?
