    Default faster than light

    Ok, forgive me for my lack of knowledge. I'm curious but uneducated.

    Anyway, I remember reading that light is technically a particle, and that they managed to weigh light. I'm not sure if this is true, please correct me if I'm wrong. That said, could there possibly be particles moving faster than the speed of light that we are simply unaware of? If something could move faster than light, could we even see it to identify it?

    Just musing on my day off

    Also uneducated on the subject but I would assume we would still see it, just a past version of it.
    If I am not mistaken our vision is based on light and how it hits/reflects off objects.

    So, before our vision registers it, it will have moved on.

    That's assuming it is on a path headed directly at you and a light source was in place prior to it passing said source of light.

    Everything that has properties aligned with the space-time continuum does not exceed the speed of light.
    There are some questions about a theoretical transmition of information faster than the speed of light in quantum dynamics. This must not be confused with mass or energy traveling faster than the speed of light. Basically as Energy and speed are connected, for a stable universe to exist, the speed of light must be a constant, that can not be exceeded. Otherwise, Energy would be permanently spawned from nothing and there would be no solid matter in the universe.
    The idea of letting mass travel through time or warp around (on a scale that exceeds the size of atoms) to our current understanding does not work. Science goes from the phenomenon to the theory to the method of observance. You don't just dream up stuff. This approach has no merit. That the universe works does grant us very close certainty to knowledge that time travel wont work. That sciency fluff talk about contrary speculations is tabloid fodder for people who wouldn't know that.

    Shut Up, Dr. Who.
    It's more fun to guess.

    Its more fun to know. There are enough spectacular and exciting things happening in reality than recreating some dorky scifi lit. Real time travel would be just as different from movies as real fights are from martial art flicks.

    Stay frosty.

    think of time like a vase

    then smash it

    then chew on the glass shards

    now you know why you cannot exceed the speed of light.

    There is a particle that travels faster than light... BUT both particles need to go through water for that to happen. It's slowed down less by water than light does and therefore travels faster.

    Just a stupid thing I once read on a flyer-like thing on the wall in the science class.

    Yes. Some particles move faster than light in water. But that's because the photons slow-down. For actual conspiratorial stuff, look up tachyons.

    Speed of light as in the constant speed of light, not whatever speed light happens 2 be going.
