    Allow me to guide you to better understanding of this subject: prove me wrong here: I say that a light bulb really doesn’t emit light, if really sucks dark.

    How about if instead of a shadow you used a strong laser pointer using the same illustration, with a small flick of youre wrist from earth makes the laser pointer on the moon travel faster than the speed of light and that would be traveled information.

    • Introverted Dawg
      Introverted Dawg 4 days ago

      That will just create a sort of wave of light that will still take time to reach the moon. Can't overcome the speed of light. There would be a tiny tiny lag between your flick of the wrist and the image on the moon, however negligible that may be.

    One thing to remember: There is no such thing as a 100% True FACT.
    A FACT is a half-truth. It was a Fact that the earth was flat, then it was a fact that is was round.
    It's 100% true until proven incorrect.
    Great video

      +Pootis Spencer Here it tells you about the state of the other particle, how's that not information?

    • Pootis Spencer Here
      Pootis Spencer Here 8 days ago

      Quantum entanglement doesn't carry any information since it's purely probabilistic. Information cannot travel faster than light.

  • Filiberto Gutierrez

    What if we find a new faster way to send information. By blasting light and casting shadows of information.

    • Pootis Spencer Here
      Pootis Spencer Here 8 days ago

      That doesn't make any sense. The shadows would still only appear after the amount of time it took light to travel there.

    Darkness isn’t the oposite of light. Its the absention of light. So its not measurable because if it was it would be some source of light that is being measured

    Darkness is faster than light, because the darkness is the light that hasn't reached a place yet, so no matter how fast light travels, darkness is always waiting for it at the end...

    But at 3:04 this also happens when, by blurring your vision, you bring two fingers together and the same effect happens. So it’s not exclusive to shadows.

    We already don't know the things we don't know. Acquiring specific knowledge characterizing some of those things reduces the number of things we don't know. The discovery adds nothing to the volume of our ignorance, any more than a mid-journey discovery that I underestimated the distance to my destination makes that destination farther away. A gain with no loss is always a net gain, so it doesn't seem correct to say that learning new things increases our ignorance.
    Another way: you are on a ladder so tall you can't see the top. You climb one rung and find that you still can't see the top. There is no doubt that you are closer to the top than you used to be, even though you still don't know where it is. You have increased the lower theoretical limit of the ladder's height; you have reduced the number of possible heights it could be.
