comment Is the observable region of the universe within the event horizon of a super-massive black hole?
I'm not able to see how the answer rules out the possibility that we are inside the event horizon of a blackhole that is extremely massive (with event horizon close to a trillion trillion light years, ignoring for the moment the number of Fermions needed for that). Wouldn't space be almost flat and the curvature measurements will be in line with what we observe?

comment How can Ohm's law be correct if superconductors have 0 resistivity?
So how many such "laws" are only approximations? Is gravitational law also like that?

comment How can a singularity in a black hole rotate if it's just a point?
Why a ring and not a disc? Even a disc can have angular momentum and the velocity of a rotating disc need not be as high as that of a rotating ring to keep the same angular momentum. In this regard, a disc is more optimal than a ring. (assuming optimal implies lowest angular velocity).

comment What exactly is Electromagnetic Radiation?
I meant a great circle on the sphere where the wave's intensity is maximum

comment What exactly is Electromagnetic Radiation?
One thing I don't understand is that the waves should really die out as the move out in a phere at inverse square rate. I am assuming you meant that at a large distance the "surface of the wave" appears flat. This is analogous to a 2D wave from a pebble dropped in a pond. Does a single wave generated due to one oscillation have a preferred plane of propagation in the surrounding sphere or is it uniform in all directions?

comment Do quarks really exist?
What is "something else that could be like a quark"? If it quacks like a duck and walks like a duck then it is a duck.

comment Does black hole formation contradict the Pauli exclusion principle?
Does it mean that Pauli's principle does not prohibit particles occupying the same state, but rather it says that there will be a resistance when this is forced upon the particles (a kind of repulsion/pressure).
