Whenever you hear about scientists “breaking” the light barrier in physics, it always turns out to be a kind of cheat involving invisible cute entanglements between particles, not actual transfer of matter, or super-ephemeral “four-wave mixing” that’s really more a trick of addition than any violation of relativistic spacetime, or the “evanescent modes” of quantum tunneling—when experimenters are able to move photons instantaneously beyond a certain length of barrier or prism, which is really more like teleportation or time travel than faster-than-light motion. That would still be very cool if it had any application for classical mechanics, but doesn’t apply to particles with mass or anything on our complex molecular scale like humans or spaceships.
