                               What I want to know

-how are the northern lights made?

- what are the other galaxies called?

-why does earth have air and other planets do not?

-what makes black holes suck thing up?

- how fast is a black hole?

- does a black hole move?

                            What I already know

-light is slower than a black hole vacuum.

-the sunset on Mars is dark blue.

- you can not walk on Jupiter, Saturn, Uranus or Neptune because they do not have a solid surface. 
-unless you're faster than the speed of light you cannot escape a black hole.
