State of the field
The Standard Model and general relativity are spectacularly confirmed yet known to be incomplete: they do not combine, and they leave dark matter, dark energy, and the quantum-gravity regime unexplained.
The gravitational anomalies attributed to dark matter are caused by an as-yet-undetected, weakly-interacting massive particle (or similar) beyond the…
Space and time are not basic but arise from a deeper, possibly information- or entanglement-based structure; gravity is a thermodynamic/emergent pheno…
The observed anomalies reflect a breakdown of Newtonian/Einsteinian gravity at low accelerations rather than unseen mass.
Weak-lensing mass maps of colliding clusters show the gravitational mass leading the X-ray-emitting gas, hard to explain if all mass is the visible baryons — st…
Rotation velocities stay flat far from galactic centers instead of falling off, implying either unseen mass or a departure from Newtonian dynamics at low accele…
The most sensitive WIMP dark-matter search to date reports no signal, excluding large regions of candidate parameter space and constraining the simplest particl…
A single acceleration scale reproduces many galaxy rotation curves without dark matter, a regularity (the radial-acceleration relation) that pure-particle dark…
Verlinde proposes gravity is not fundamental but an entropic force arising from information associated with the positions of matter — a speculative but explicit…
