I am a layman. I liked - and paid attention in - physics and math classes (high school physics + 2 physics classes in the university). I know little about GR and less about the math behind it; I wouldn't recognize a tensor if it hit me in the face. I'm willing to learn, however.
A radiating...
Thanks, this cleared up things nicely.
I got the gravitational potential energy formula from Wikipedia and it turns out I copied it down carelessly. Wikipedia uses a capital R, not a lowercase r:
U=-G\frac{m_1m_2}{R}
(found in...
As I have apparently horribly misunderstood something basic, could you (or someone) please help me figure it out? What is r, what is R(m) and why can't one be substituted for the other?
Thanks for the answers.
For the main point:
As far as I know, in a Newtonian bound system the binding energy is radiated away during the formation of the system. The mass of the resulting bound system is the mass of its original components minus the mass-equivalent of the binding energy...
Hi.
I tried to calculate the gravitational binding energy of a black hole, but I suspect that I did not do it correctly.
I used the following formulae:
black hole radius (Swarzschild radius):
R(m)=\frac{2Gm}{c^{2}}
gravitational potential energy for separating two masses from...
