The absurdities of modern theoretical physics are so easy to see, but yet not acknowledged. The emperor has no clothes.

comment Why do we not have spin greater than 2?
The OP is talking about the spin of force carriers, photons, phonons, gravitons, W bosons, etc. Heavy stuff like particles or baseballs can have any spin.

comment Do two beams of light attract each other in general theory of relativity?
Perfectly parallel beams in the small field limit only, which is not the OP question.

comment Do two beams of light attract each other in general theory of relativity?
From your answer it seems like 'Yes' is more correct than 'it depends'. Especially if you look at the point you make about parallel light being the only exception (which is only true for one case out of an infinite measure of cases in the weak limit).

comment Arguments for and against Many Worlds?
There is indeed an exploding amount of energy - but since its in different MW universes, no one notices. If you swallow the MWI, one not need worry about the 'source' for all these universes. But the 50% comment above is wrong - every Universe measures the same total energy all the time.

comment Should gravitational waves be discovered already?
Jerry, thanks. It would be nice if that graph had some 50 parsec double black hole coalesce on it, though.

comment Should gravitational waves be discovered already?
There must be a 2D graph with regions on it showing our capability to observe vs expected event strength?

comment Is the surface of a heavy sphere bigger than $4 \pi r^2$ due to general relativity?
The rope makes it tricky its better to think of taking steps, each measured as exactly 1 metre, either in a circle around the planet (to determine the area and hence an R) the other, using the same measuring stick, is a measure from the centre of the planet to the surface.

comment Is space stretched with no limits by a black hole?
I don't think the space around a black hole is well represented by Schwartzschild coordinates, which break down in a perfectly reasonable region of space time. Schwartzschild coordinates only tell you what it looks like from afar, not what is actually happening at a given point.

comment Many-worlds: how often is the split how many are the universes? (And how do you model this mathematically.)
Nice answer. I find that many worlders do actively sweep this under the rug as often as possible. You could improve it by attempting some calculation at some level - for instance merely assuming that there is only one observer - you - in the Universe, how many universes split per second? I can see the coarse graining being undefined even for that!

comment Coulomb's Law in the presence of a strong gravitational field
Coloumbs law holds perfectly well for say a charged back hole. r is defined though via the surface area of a spherical surface. If things are not symmetric (e.g. electron outside a non charged black hole) then the same principle applies, but there is some more math to do to account for the non symmetric curvature. So I am not sure one needs to resort to fields for the OP.

comment On the foundations of quantum physics
Spiral? More like a random walk on a slight incline - science has stumbled in the dark in the wrong direction for hundreds of years at a time in any given subject. The Earth was the centre. The heavens ran on circles. Gravity was transmitted instantly. Phlogiston, Superconductivity, etc. The list is long.

comment How much is quantum computation changing the interpretation of quantum theory, and, if at all, how?
What is wrong specifically. Quantum Computation is in theory super capable. That's a fact. The energy required to run a Quantum computer does not scale with complexity, so is order zero. My opinion of those two facts is that it shows the hole in QM loud and clear."Put another way, we can store 10^300 numbers on our 1,000 particles simultaneously."
