    Yes there is particles that can excede lightspeed but matter can not , inorder matter to exceed light speed it has to change state to energy

    Do you have any citations for this, because that runs counter to anything I have ever heard....

    I’m not saying you are wrong, mind you, just curious about the source.

    He must be referring to tachyons. Which are hypothetical and probably about as real as the square root of -1.

    Unless I have missed something

    That is 8 years old.

    IIRC there was a flaw in their thinking

    Not just a good idea--it's the law.

    186,000 mile per second. Hrmmmph, there you go taking someone's word for something without any real proof. I mean has anyone ever got a ticket going that fast, well have they? Hmmmm?

    I remember the first time we measured the speed of light.

    It was a real sense of accomplishment.

    In the pre-digital television days, when you could get ghosts on the screen, if you could determine where the reflection was coming from it was pretty easy to measure C.

    But that was only the second time we measured it.

    Instead of going to bed, I found this: What if you "filmed" a flash of light at 10,000,000,000,000 frames per second?

    space its self is expanding faster than the speed of light , photons travel at the speed of light,Tachyons do as well, but any matter would have to convert to energy to travel at that speed , because as matter approaches the speed of light it becomes more dense specifically it mass increases precipitously ( this acording to Einstein's theory of relitivity E=MC 2) { energy = mass X (speed of light X speed of light) or the universal constant squared}

    in theory if you took a pencil lazer pointed it upward , then waved in the air from hoizon to horizon the beam would cover an arc many millions of light years in a few seconds.

    Light isn't the fastest thing known. Milk is.

    It's pasteurise before you see it....

    In the lazer pen experiment, at no point is any photon moving faster than light. It is only the end point that is changing position. Think of someone swinging a hose.

    This article does not support the idea that neutrinos/(hypothetically tachyons) travel faster than light. It actually documents the 5 separate studies that demonstrated neutrinos follow the speed limit. The original OPERA study was shown to be the result of faulty wiring.


    As far as space time expansion is concerned, velocity is a localized concern, governed by general relativity. The map may be expanding, but the coordinates stay the same. This guy does a better job of explaining.

    Does this mean that any broken coat hangers in my wardrobe have been sneaking out at night, exceeding the speed of light and then sneaking back again? (Possibly before they had left in the first place)
