A second line of research for these facilities should generate additional support and funding. Very nice.

Thanks n_FA. Does DM have to be a particle?

I don't think so. It could be something much more interesting like a point defect in spacetime.

hey nFA, here's a Dr. H blog from a few years ago.

at the end of the blog, she says she's excited to be working on this, because nobody else has.

Interesting. Thank you.

I think that she may exaggerate a little when she says no one else is working on spacetime defects. There is quite a bit of literature on it from the string theory folks. Ethan Siegel gives a pretty cogent summary here:

https://www.forbes.com/sites/startswith ... b85dd0281e

It has even been speculated that Planck's constant (and so all quantum phenomena) arise from torsional defects in space time:

https://link.springer.com/article/10.1007/BF00671851

https://www.sciencedirect.com/science/a ... 1652900407

https://arxiv.org/pdf/1701.01829.pdf

Now at the risk of being boring, Einstein Cartan Sciama Kibble gravity is a natural arena for torsional defects.
