Thanks for recapping what I have already said... About your comment "He is confusing the models we use, and which have specific areas of applicability, with the reality." Understand that two models cannot use opposing postulates about space and both describe reality, especially about space. Thus it is an inevitable truth that the other is wrong.

It does in fixed background view And they both cant be correct. So you cannot have an inclusive definition if either GR or QTs view is wrong

I have already talked about the difference between GR and QT and I said I favor the view of Newtonian Gravity, Maxwell dynamics and Quantum theory. By what cause... do not put me in a box good Sir.

+1 Furthermore that particular volume does indeed interact with energy (in the form of EM waves since there is no such thing as 'pure energy') as evidenced by the easily measurable complex impedance of free space, usually denoted by the symbol Zo. -- Maxwell theory is background independent. Its only in GRs view where space can slow down objects or cause any visible manifestations on objects or bodies With that said, Energy is temperature/matter/waves/etc. Is there any other theory in standard physics besides Einstein's GR that predicts that space can affect energy? The answer is none. Makes you wonder. A predetermined stage. A stage that had all the properties to allow manifestations such as the big bang

Finally we agree, but you named one property. Space is volume. Neglected the rest. But I was drawing you to the most important property whether it interacts with energy/matter or not.

You are talking about properties of space and not what space is. I personally favor the view of Newton and Quantum theory so from my point of view: SPACE is an entity that cannot interact with ALL forms of energy. In relativity forum? While your very answers where based on QT. Again its always amusing strange.

The OP did not specify which according to my knowledge. And as I said before either GR space or QT/Newtonian Space is WRONG they cannot both be correct. This is the fundamental reason why GR cannot be quantized.

@stringjunky I have already made this clear that in GR space is different than Newtonian and Quantum physics. Thus I said you need to make a choice.

So you agree? Ur reasoning is always amusing to me. An electron has spin... do u agree that an electron is spin? Basically that is all u have said Space being infinite is another property of space, so is its dimensions another property.

I know what you just said sounds correct based on Machian thinking etc. But DO NOT say "empty space does not exist as distinct entity" What are the postulates of quantum mechanics? What are the postulates of Newtonian Gravity? Volume is a property of space and matter but it is neither space nor matter. And as for the vacuum energy that is not a property of space (if u followed my earlier thoughts, I raised a question. Can space interact with matter/energy? ) Your answer already assumes this is true but you are using vacuum energy of QT which is a paradox. Vacuum energy based on E >= mc squared . Is still a property of energy and not of space. Check the calculations in QT.

Space is not volume. Matter has volume so does space, whether that volume in R*3 is infinite or not is what u nd I should be discussing

Ten pages and no sensible answer to what space is... In QT, space is a pre-determined entity in the postulates of QT. And any form of energy (matter, temperature, time, etc.) can never cause any disturbances on space -- in a nutshell space has different units to the fundamental units this inhibits any and allall forms of interaction. GR on the other hand does not share this belief. Stating that energy(time) and space can cause interact with each other and hence space disturbs matter and vice verca Obviously either QT or GR is wrong about what space can or cant interact with energy. As to what space is, why it has the dimensions it has, whats it prime cause... is beyond the standard model and only speculative ideas can be suggested. For now the true debate is can space is disturb forms of energy or not.
