Controversial new theory of gravity rules out need for dark matter
Controversial new theory of gravity rules out need for dark matter
Exclusive: Paper by UCL professor says ‘wobbly’ space-time could instead explain expansion of universe and galactic rotation
This theory is pretty neat being part of the very few groups looking at the notion of spacetime as continuous and quantized matter as a secondary effect (as they self-describe, a "postquantum" approach).
This makes perfect sense from a simulation perspective of a higher fidelity world being modeled with conversion to discrete units at low fidelity.
I particularly like that their solution addressed the normal distribution aspect of dark matter/energy:
Here, the full normal distribution reflected in Eq. (13) may provide some insight into the distribution of what is currently taken to be dark matter.
I raised this point years ago in /r/Physics where it was basically dismissed as being 'numerology'
But proponents of a radical new theory of gravity, in which space-time is “wobbly”, say their approach could render the elusive substance obsolete.
People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly wobbly, timey-wimey stuff.

I mean, a doctor said it, so...
