What do you define as matter?

Clearly, we are not all using the same definitions. So there is some ambiguity. And words are imperfect. So, it seems the question is...

So, we're concluding that the answer is either yes or no, depending on what you include in the definition of the word "matter".

Who specifically claims that, and where did they claim it? Usually if you look in context then you can see why someone said something.

I would prefer your thoughts.

100%. Without any doubt or hesitation.

By “usual” I meant “usual for the infinite plane”. Most people, when solving the infinite plane problem, implicitly choose a boundary...

This is also what I would say is the key difference. They have different domains. It can be that on the worldline of a given clock they...

I'd say that the proper time of a clock is only defined along its wordline, whereas coordinate and cosmological times are defined over a...

No. Proper time does not have a notion of simultaneity like coordinate time does.

Here is a valid derivation of the electric field for an infinite plane, based on the result for an infinite wire of uniform linear...
