Despite recent some initial evidence to the contrary,[1] I'm still a fan of the idea that dark mater is actually concentrations of matter/energy outside of our universe.
If string theory is true, gravity does leak into the multiverse, and we survive the Great Filter, then someday we may be able to use gravity to communicate universes outside of our own.

- The_rationalist 8y agoThen why would dark matter be detected in galaxies but not in void space ? Why would those external world matter/energy be spatially syncrhonised at the place of galaxies ? Ockham Razor to the rescue.
- matt_kantor 8y agoI'm just a layman, but the parent said "if string theory is true, gravity does leak into the multiverse". Given that I'd imagine the clumpiness of our universe could influence the clumpiness of nearby universes (and vice versa).
- slacka 8y agoExactly. Not all galaxies have the same % of dark matter.In fact some have none.[1] Maybe those with little to none, formed by random fluctuations, while others formed because of the attraction to dark matter in their vicinity. https://www.smithsonianmag.com/smart-news/galaxy-without-dark-matter-shakes-astronomy-180968628/ https://www.smithsonianmag.com/smart-news/galaxy-without-dar...
