Post-quantum gravity could explain the rotation speed of galaxies, which is normally seen as evidence for dark matter

A potential new theory of gravity that ruffles the fabric of the universe, allowing space and time to vary erratically, could solve some of the largest mysteries in physics and do away with the need for dark matter, say its proponents. However, others say much more evidence is needed before this “post-quantum gravity” can be taken seriously.
Most cosmologists believe…
