From Nature’s Time to test time: “The predictions are based on a lower-dimensional view of spacetime: two spatial dimensions, plus time. Spacetime would be a plane of waves, travelling at the speed of light…The third spatial dimension of the macroscopic world would be encoded in information contained in the two-dimensional waves. ‘It’s as if, in the real world, we are living inside a hologram,’ says [Craig] Hogan[, director of the Center for Particle Astrophysics at the Fermi National Accelerator Laboratory]. ‘The illusion is almost perfect. You really need a machine like GEO600 [in Germany] to see it.’”
