    So you hear people say, nothing can move faster than light, well that's BS. Nothing can move faster than light in a vacuum, but there are situations where other things can move faster than light when you take different mediums into account. Take a very thick piece of glass, and fire a beam of muons at 99% the speed of light through it with a laser also aimed at it. The light will slow down in the glass, but the muons can pass through glass without interacting with it, so the muons that enter the glass at the same time as the photons from the laser will exit before the photons.

    actually, you can go faster than the speed of light, its just that you cant send useful information faster, so its kind of pointless

    with quantum entanglement you could separate 2 quantum entangled particles across the universe and if you manipulated one particle, the other one would instantly do the same at the very same instant, which would be faster than light speed

    although the information that is used while doing this is gibberish, so we cant use it for our advantage

    And if anyone is ever able to prove tachyons exist even the "nothing can move faster than light in a vaccum¨will be obsolete.

    That seals it. The British can no longer be trusted with the English language.

    It's the same issue as maths vs math. This site says that both are equally acceptable abbreviations, though of course everyone secretly knows that maths is correct :p.

    It's like the End of the World. People have"predicted" so many different dates that eventually someone will get it right...

    My favorites are the people who have predicted multiple different dates over the years. Surely the next time, they will be right.

    Their only problem is that if they ever get it right there will be nobody left to brag about the fact :)

    Except the ones that will somehow be able to enjoy their eternal bliss while 99% of the humans who ever lived are burning forever in a lake of fire...

    The entangled particles could be said to not really be moving or traveling, it's just there, but changed by the other particle. Einstein was right, it is spooky ;)
