The electromagnetic field is mediated by virtual photons according to QED. These virtual photons, by virtue of being massive, should respond to Gravity. Therefore, in the presence of strong gravity such as that of a black hole range of EM force should be affected because very few virtual photons...

That depends on university and no. of hours you work as TA/RA. But usually its about $18k to $22k.

@JesseM I agree with your 1st point but numerical simulations are the best possible way to understand such phenomena at the moment. It didn't say it necessarily means that, but it is a possibility. Further in the same article author mentioned that even a fast rotating black hole can tear itself...

http://www.scientificamerican.com/article.cfm?id=naked-singularities In this article author mentioned that naked singularities can form as a result of collision of two black holes. That means mass can be ejected from a black hole as a result of collision. Because if black holes collide such...

Lets say you are in an inertial frame watching a particle moving in circle of radius r with velocity w. Then v=rw is valid. Only thing is that w would be different from w as measured in the instantaneous rest frame of particle because of time dilation. So value of w would be different but...

If an object starts moving relative to you then its mass would be larger compared to when it was at rest relative to you. What is invariant is rest mass i,e the mass of any object when it is at rest relative to you.

Based on the fact that you are bored of your job, I infer you need something interesting. So I would suggest you to start with some modern physics like Quantum Mechanics, Special Relativity. If you feel difficulty somewhere you can always revert to basic maths and classical physics. Doing...
