Last I heard, all proposed "altered rules for gravity" run aground
on the little problem that they predict different orbits than the
ones we actually see for nearby objects, such as planets and the such.
Sometimes the deviation is small, but again, last I heard, there weren't
any contenders other than "there's something massive there".
This is especially true of the latest gravitational lensing discovery.

"There's no dark matter" was hanging on by a thread before.
With this latest, the thread has snapped and it's hovering
over the chasm like a Warner Brother's cartoon character who
hasn't yet realized he's walked over the cliff. So to type.

Not that the various theories about precisely what dark matter is
are having an easy time of it. It's a tough problem. But
pretending there's "no evidence" as others have is a non-starter.
