00:00Anyhow, today I gotta go fast, like so much Sanic the Hedgehog,
00:04because we're talking about hyperspace, subspace, and all the other made-up spaces
00:08that help our fave starships explore the cosmos at faster-than-light speeds.
00:13That's about a billion kilometers an hour,
00:16which is how fast something moves when it has no mass whatsoever, like a photon.
00:20Photons are straight-up anorexic, B.
00:23And A, they're waves of electromagnetic radiation
00:26traveling through space at the speed of the cosmological constant.
00:29Which they indeed define.
