Physicists blithely refer to space (and spacetime) as something that is a known thing, as if it were some 3d or 4d mathematical metrical entity of 1800s mathematics that Einstein used. Today it may be some more cellular structure of 2000s quantum spacetime models (e.g. LQG). And then there are things called fields hypothetically filling space(time). This is useful to read again (one of VIctor Stenger's last essays): *Materialism deconstructed?* https://www.huffpost.com/entry/materialism-deconstructed_b_2228362 We really don't know what any of this is. @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
