I did not get both of these formulas from the same source. I merely came across the event horizon formula with the symbol M simply labelled as "the mass of the black hole". I then independently learnt of the formula for the irreducible mass from another source. So yes, the distinction was...
Posting this as I have so far not been able to find a straightforward answer to the following question. The formula for the outer event horizon of a kerr black hole is given by the following equation:
$$r_+ = \frac{GM}{c^2}\left(1+\sqrt{1-\frac{J^2c^2}{M^4G^2}}\right)$$
Where ##J## is the...
That is very comforting to hear! If I may ask, what is the exact nature of these jobs these physics PhD's are undertaking? And what is the general job title given to them, if any? (I would like to know this for future reference if looking for industry jobs becomes a necessity)
<Moderator note: Moved from academic guidance to career guidance on Scott92's request. Reason: The question primarily addresses job opportunities in dependence of PhD subject.>
Hey everyone,
I'm a student who is currently undertaking a Master of Physics (coursework & research) at the...
