    Why no one has ever measured the speed of light

    Yeah, I know, the speed of light is a "known constant", blah, blah, blah... We take things for granted as if science always has all the answers. But no one has actually ever measured the speed of light!

    Sorry. Who said no one has measured speed of light before?

    Only after 1983, physicists has redefined the metre in SI as the distance travelled by light in vacuum in 1 / 299792458 of a second. And after that, speed of light is an exact number. Before 1983, speed of light is a measured physical constant.

    Re: Why no one has ever measured the speed of light

    Of course the fundamentals of relativity also say that: "According to relativity, time stands still at the speed of light. Moving at that speed, the second hand on the clock would not have advanced, in the least. ... No time passes on the clock, traveling at uniform light speed, which means that no time passes during a photon's journey, either."

    So if speed is DISTANCE over TIME and at the speed of light, time stands still.... that in itself is a bit of a problem...

    Also, always allow room for changes and improvements in scientific terms/definitions/concepts as they are bound to change over time as well.

    Speed of light may not be a constant after all.... Is is TIME to rewrite the physics textbooks? "The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space."

    With this video I confirmed my suspicions that, in audio

    - we need better science and better instruments to measure the differences that our ears already catch;
    - this opens an explanation for the directionality of the cables and even for the difference between a coil cable and a stretched one!

    Ah!

    Not really. We just need to understand the quantum like computer that is our brain a bit better. Way too many discrepancies and the hearing acuity as well as processing evidently greatly varies from person to person based on many different aspects of physiology. The fact that our memory is not that great at remembering the sounds as much as we like to believe in it as audiophiles, also doesn't help. We only remember 2-4 seconds worth of a tone... Not to mention a complex, multi-instrumental sound.

    On a separate note, yes, on a quantum level, where the subatomic particles that our reality is based on, including ourselves, those brains and ears of ours, as well as even the electronics and transducers as well as everything that connects them together... well, those subatomic particles are actually blipping in and out of existence. Given that fact, anything is possible from how we perceive the reality and what we hear, see, remember, etc... it's all just electric impulses in our brains after all. Not to mention the all kinds of funky quantum level stuff going on with the electrons and their interaction with various components and their atomic/subatomic structure.

    But how do we trust measurement instruments if they don't use an after market power cord for crying out loud!

    Somehow I knew someone was going to reach this conclusion… Why no one has ever measured the speed of light
