Simulation of Sagittarius A Press Space or click to create a blue dwarf. Up and Down Arrow to change the colour of Sagittarius A. I will add music soon.You can give music ideas in the comments (space music or something)
Thanx to the "Welcome to Astronomy!" studio for the idea. Black Holes are so dense and heavy bacause a lot of matter is squeezed into it. The massive mass makes the gravity extremly strong. Even light can't and won't escape. Light ( a photon ) does not have any matter but because of the theory of relativity it can't escape the black hole.
