Vanadium 50 said:Why (or how) is this different than the Pound-Rebka experiment? (done 59 years ago)
jedishrfu said:Each new proof of GR necessarily puts a hard experimental limit on the kinds of theories that can replace it.
jedishrfu said:I think we are in agreement here. Some of the current theories have to be or have been discarded because they failed to predict what has been measured.
This paper talks about binary pulsars (circa 2008) and how experimental results have confirmed GR and limited other alternatives to GR:
