Those aren’t theories, they are interpretations. None of them make different experimental predictions for anything, so none of them are...

So, what happens if the points all lie on the same great circle? In this case they can be sorted such that their distances all just add...

You are exactly correct. As you saw from information above, a black hole is created when the core is above somewhere between 2.2 and 3...

Okay, isn’t the operator ##i\frac{\partial}{\partial p}## required to be hermitian? This would force the boundary terms to be zero.

Aren’t you assuming a 2.2 solar mass star will retain 2.2 solar masses in its later stages? Not a bad assumption, I admit, but an...

Well, I only need a factor of 11,780. Seriously, stars can gain and lose mass. One of the first things I looked at with the telescope I...

This is a fascinating thread. It starts with the statement that something like 0.1% of stars become black holes and goes from there. I...

If the potential needed to move charge carriers across the junction were zero, particles would continue to just fall into holes all day...

The potential A_{\mu} is NOT a 4-vector. The fact that we can always choose A_{0} to be zero in ALL Lorentz frame show that A_{\mu}...

Or, track the prize orderings and remove them at the end which is what I did to get deconfused.

Presumably the (distinct) prizes are given given out in a predetermined order, and we don't need to add extra statistics to count the 5...

So, if boy 1 gets prize A first then later prize B, this is counted as different than getting B first then A? I would have counted final...

Out of interest, what is the make and model of the radio? The internal loop antenna may be tuned with a variable capacitor, and you may...
