MYTH: Nothing can go faster than light.
Reality: Wrong on a few levels.
While light can move unimpeded at 299,792,458 meters per second in a vacuum, it slows down when it travels through different substances. For example, light moves 25% slower through water and 59% slower through a diamond. Particles like an electron, neutron, or neutrino can outpace photons of light in such media — though they have to bleed off energy as radiation when they do.
