Sure, Ralph.

"Same instant" defined how?  Also, how to communicate sameness from the
different sensing locations that are separated by a distance, Ralph?

"Normal" how, Ralph? Do you mean "Newtonian", Ralph?

Or that SR is valid.

Of course such measurements have been done, and cannot come up with any
sort of absolute speed, Ralph, because there isn't such a thing.

But no aether supports Einstein's theory, Ralph.

It's already been done, Ralph.
