comment What makes a space a real space?
When I am talking to my mother I don't use the word "space" and when I am solving a physical problem I formulate it mathematically... What's the difference between your question and "Why would we interpret something that seems to move as something really moving ?" ?

comment What makes a space a real space?
Real space if not a very well defined concept: we just use it when we want to distinguish from another space we are using, like reciprocal space.

comment What makes a space a real space?
Please stop with this "philosophy" tag: either your question is a valid question about physics as a science and it doesn't need this tag or this is not a valid question and it should be closed.

comment Is it possible/correct to describe electromagnetism using curved space(-time)?
The answer of Eric is really interesting and correct and explain that in their general form, Maxwell equations can be applied in the case of a curved space-time. But I think the question was: the basic gravitational potential is similar to the electrostatic one, so can we describe electromagnetism using general relativity. As you accepted the answer, you should maybe modify to question to make things clear.

@Stefano: Well done but I think it is useless to argue more with that kind of people :p

comment Meaning and application of convolution or deconvolution in physical sciences
I think this question is too broad to be answered correctly. We will just have an endless list ... Why are you asking ?

@Marek: right again, I should really sleep (3 am ...) and I'll look at this later.

comment Why does the water level equalize in a series of tubes?
No because a fluid cannot sustain transverse constraints. You have to consider only the water just on top of the point (infinitesimal volume) where you want to have the pressure. The force exerted by the water is compensated by the wall of the pipe when they are not parallel.
