- Comment on Astronomers discover third galaxy lacking dark matter, challenging the assumption that dark matter is an invisible glue needed to hold galaxies together 2 weeks ago:
Uuh, with three galaxies you can finally do some statistics on whether they are merely an outlier in a distribution or there is an actual mechanism at work here.

I’m going to get a cutting and give it a try now.

Photons do have energy (in the stress-energy tensor), so they curve spacetime too, but all particles follow geodesics regardless of mass…so…I guess it is all the same from gravity’s PoV…it is QM that makes a difference…but entanglement doesn’t either (like gravity)…wink wink, nudge nudge…
PS: ok, ok, radiation’s energy density is 1/a⁴ and baryons is 1/a³, so there is a distinction there to having inertia towards gravity.
