comment Does the weight of an hourglass change when sands are falling inside?
brevity is appreciated but a link only answer is not very helpful. If you could possibly paraphrase or share some relavent points based on the op's question to expand on your answer it may be more helpful.

comment Everyday example of diffusion unobscured by advection, wetting etc
That sounds like very interesting experiment and using a webcam and computer to plot everything and get the students involved is great.

comment Does a black hole have an interior or does the spacetime manifold itself end at the event horizon?
I believe you have answered your own question time and space can not continue as normal past the horizon therefore nothing we understand can exist without time and/or space. -1

comment What is the experiment where subatomic particles appear to foresee the future?
Would you be able to be more specific? Possibly include a link to the documentary or a related article about the experiment.

comment How can two time theories be compactified to 3+1 without any Kaluza-Klein remnants
Great comments if someone could combine them into a coherent and collective answer that would be great. If I have the time tonight, I will try to do this myself.

comment What else does the fabric of space-time do?
O clarify there is no "fabric" in the true sense of the word there is only the distortion of space coordinates due to massive objects gravitational pull.To address your second question Gravity ie "fabric" has a great list of effects on almost every aspect of the universe.

comment What kind of “camera” and “light” source should I use to detect the intermediate path of a light beam?
It is not possible to see light move you can only see light being interacted with I.e. reflected or absorbed.

The fan pushes the air and the air pushes on the blades of the fan blades push the base of the fan and fan pushes on boat. Am I missing something here?

Relativity is a very misleading name.

comment Observable universe does it account for farther away galaxies measure of the observable universe?
Since there is no possibility of recording the other observations how can we be certain that there view would not just stop at our current boundry?

comment How can something happen when time does not exist?
Intuitively the geodesic is part of a large structure and the singularity created the geodesic that appears to be flattening (dispersing) back into this larger structure.

There may be some confusion between fluctuations and singularity. Fluctuations do not need time while the singularity describes time more specifically inflation.
