PD:
What makes you think that something that does not contain matter is
nothing. If something has properties but matter is not one of those
properties, does the reality of those other properties go away?

KS:
So why don't you give us a description (a definition) what is space?
IOW What is having these properties that we observed.

Space has permeability, permittivity, two dozen or so local gauge field
values, and a local metric, and all of that without a scrap of matter
to embody them.


KS:
Do you think that calling the ether as nothingness is a refutation of
the existence of an ether? <shrug>

PD:
No, the only one that is calling empty space nothingness is you.

KS:
You rejected the term ether as space and you refused to define what is
space. Then you insisted that this empty space have properties and it
can expand faster than light and carry the galaxies along with it as it
expand. So are we suppose to accept any absurd thing you spew out??
IBTW Einstein call space as empty space and from that I interpreted
that he meant nothingness.

That would be a bad interpretation, in my opinion. Moreover, Einstein
has been dead for fifty years and we have learned a little more about
space since that time. About all one can say about what "empty space"
means is "devoid of matter" where matter refers to on-shell fermions.

PD

If you got another more valid interpretation
lets have it.
