Sorry, replied on the wrong thread…
It seems the physicist’s replies are in and Patrick’s claim is refuted.
The error here is the ‘finite and equal to c’ claim. That gravitational waves and light travel at the same speed is a stunning revelation, but unless there is a synchronised clock at the source it doesn’t tell us anything about the one-way speed.
And this one also:
He actually calls his model the ASC (Anisotropic Synchrony Convention) and it makes no claims about an expanding universe (although Lisle does agree). It is a convention and as such can’t be falsified when compared with the ESC.
Special thanks to the @physicists for their contribution.
