Thanks a lot, everyone. It is really helpful.

I guess it would be interesting to see the distribution of only several molecules of some material in the medium. Although they would have a very high probability to be separated but it would be interesting to find out how large and stable that separation would be (would they ever come up close...

Thank you. I will try that out of curiosity.

Thank you for providing so many useful links. Highly appreciated.

True, but sometimes it is worthwhile reviewing the existing axioms too...

Thank you, this is a great explanation. So, I guess if the material is not the same we can trace the exact mechanism of diffusion. That's helpful.

I have been wondering if there is an explanation to why diffusion always goes down the concentration gradient? If it is a random molecular movement than why do we always end up with a uniform distribution of molecules?

It is very interesting, thank you Neandethal00. I guess more experiments are required...

Thank you Dickfore and Cosmik debris. And is it possible calculate what the gravitational effect of energy (say, an electromagnetic field) would be?

So, the answer is that the local proper time may flow at a different rate due to space-time curvature created by an electromagnetic field? And according to the previously referenced article, such a curvature will be very small (if you create an electromagnetic field in a laboratory), hence, the...

Thanks jedishrfu! I have come across that article too...but I wonder if there is anything else on the topic?...My Google search was not that effective somehow...

The rate of change, whatever it may be (chemical reactions, radioactive decay, heat transfer). I guess I am interested if there is a difference between the time rate near the electromagnetic source and the time in any other place (similarly to when time is measured at the top and at the bottom...

According to relativity, time rate differs in regions with different gravitational potentials, i.e. the closer we are to the source of gravitation the slower time passes. Does anyone know what happens to time in electromagnetic fields?

Could you define "local", please? So, the object in the intergalactic space will not expand due to the strong nuclear force?

I was also thinking, in order to stop the expansion of the universe locally (say, in one galaxy), it would require the force of gravity to be equal to that of the expansion... It also means that if hypothetically, someone was in an intergalactic space where gravity would have little effect, we...
