No you aren't. Dividing the round trip time by two and assuming that is the appropriate clock offset is an assumption of isotropic light...

Umm, A can already determine t[B1] in step 1.

Here's your assumption of isotropy. Edit: I misread the OP - as PeroK says,this is a ##c/2## one way, ##\infty## the other way...

And having it confirmed by making predictions that previously were not made, and which turn out to be right.

Question about discussions around quantum interpretations

In the MWI, that doesn't "impose probabilities"--it just means that "we experience" has to be interpreted very...um, carefully. In...

Dirac's integral for the energy-momentum of the gravitational field

Actually, on thinking this over, I don't think that's what he meant. I think he meant a coordinate change that leaves the hypercylinder...
