Gravity could come from gravitons, like light comes from photons. Or maybe, like sound waves in a gas, it could come from the entropic dynamics of some microscopic thermal system. But could that really work? And could it be tested? We think so. arxiv.org/abs/2502.17575

On the quantum mechanics of entropic forces
It was conjectured thirty years ago that gravity could arise from the entropic re-arrangement of information. In this paper, we offer a set of microscopic quantum models which realize this idea in det...

Could gravity be "fundamentally classical"? Akira Matsumura and I analyzed Oppenheim (@postquantum.bsky.social) et al.'s proposal. tl;dr: A. it appears to have Lorentz-covariant scattering B. 2—>2 scattering differs at O(1) from the usual Rutherford/Newton answer arxiv.org/abs/2412.04839

Classical-quantum scattering
We analyze the framework recently proposed by Oppenheim et al. to model relativistic quantum fields coupled to relativistic, classical, stochastic fields (in particular, as a model of quantum matter c...

Look upon my TikZ, ye mighty, and despair.
