[QUOTE="Kaon, post: 74752745, member: 407930"] This is pretty much the case. For example, neutrinos (which have a mean free path of a [B]light year of lead[/B] - in other words, it can go through a light year of lead without interacting with matter) travel [I]faster than the speed of light [U]in the medium of heavy water.[/U][/I] The Super Kamiokande did excellent research in neutrinos almost by accident. When things go faster than light in a medium, they create a "photonic boom" much like a sonic boom - in this case, it is called Cherenkov radiation. The neutrinos don't actually travel faster than light in a vacuum (although, depending on who you speak to, this statement isn't necessarily true) - they have mass and travel at bradyonic (slower than light) speeds. However, in Post #37, I am saying we could have an event in which a massive body does, in fact, reach a desired point faster than a photon beginning from the same location. Who knows? [/QUOTE]
