Earlier this year, Carver Mead of CalTech published a paper which seems to be garnering a lot of attention:
I also watched the video of his talk at CalTech: https://www.youtube.com/watch?v=XdiG6ZPib3c
The Q&A at the end of this talk seemed to indicate that he may be misapplying GR equations for tasks for which they may not have been designed or for which they need proper manipulation.
The G4v theory claims, among other things, that it does away with the need for a Cosmological constant (which, based on the gravitational wave uses, I can understand) and also DOES AWAY with Dark Energy. It seems future LIGO experiments could provide supporting or refuting evidence for G4v.
My Question: How/why does this theory do away with the need for Dark Energy?
Does it invalidate prior calculations that the univerise is expanding at an accelerating rate? Or does it just describe the accelerating expansion without the need for the cosmological constant? If the latter, that still requires something accelerating the expansion, so I'm confused.
