There is a new report on the possibility that gravity might not be an interaction within QFT framework, but rather as a result of quantum fluctuation.
The average of these fluctuations is a gravitational field that is consistent with Newton’s theory of gravity. In this model, gravity is born out of quantum mechanics, but is not in itself a quantum-mechanical force. It is what scientists call “semiclassical.” Until this theory is tested further, it will remain a semi-solution; while the idea does predict certain known phenomena, it doesn’t yet account for Einstein’s theory of general relativity.
This latest report is due to a preprint uploaded to ArXiv.
Now, I can understand New Scientist reporting on something like this, because they have the tendency to report on sensational and unverified science news, but for PBS/NOVA webpage to jump onto this still-unpublished work? That's surprising.
Of course, I'm complicit on this as well since I'm reporting it here. I'm going to make sure I won't highlight something like this again in the future until it has at least appear in a peer-reviewed publication, not just in New Scientist and the likes.
