TL;DR Summary
This Dark Matter hunting is pretty popular.

Summary:We propose a search for low mass dark matter particles through momentum recoils caused by their scattering from trapped, nanometer-scale objects.
The Paper linked details a novel concept for detecting WIMPs. I hope to see more work performed on the idea in the future.

This one is particularly interesting as it would detect dark matter particles that interact only via gravity (which is kind of the null hypothesis for dark matter).

I'm glad I'm not paying for it. Oh,... wait,... :oldmad:
 
  • Haha
Likes ohwilleke and Oldman too
https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...
Many of us have heard of "twistors", arguably Roger Penrose's biggest contribution to theoretical physics. Twistor space is a space which maps nonlocally onto physical space-time; in particular, lightlike structures in space-time, like null lines and light cones, become much more "local" in twistor space. For various reasons, Penrose thought that twistor space was possibly a more fundamental arena for theoretical physics than space-time, and for many years he and a hardy band of mostly...
