What is Astrophysics?
It is physics that is not limited to our experience her on earth. It describes the dimensions and nature out in space. That is extreme space, extreme time and exteme temperatures.

What's so special about this equation?
(ds)2 = (c dt sqrt(1 - 2GM/rc2))2 - (dr/sqrt(1 - 2GM/rc2))2 - (r dtheta)2 - (r sin theta dphi)2
("Schwartzschild metric")
This equation has a lot of information in it.


Ask me about the astrophysics class I took.

more to come later...
