    1. OC is alpha Phoenix. If you’re wondering how the camera works (if you’re wondering what a disco ball looks like with this technology), it’s in his video

    2. That beam of light u tracing, so is the light that reflected on other surfaces n reached back to lens are twice or more faster than the beam itself????

    3. K, so that's actually not the speed limit of light. The real speed limit, a constant known as c (the same c from e=mc2!), represents the speed of light in a vacuum (like space!). Light having different speeds in different mediums is why diffraction exists 😁

    4. But how are we seeing the light cross the room? Is the room a perfect square and the light is hitting the camera at the same speed it is crossing the room left and right? If not then is the camera seeing the light faster than it's beam is traveling left and right, i.e. the one direction speed is faster than the return speed? See veritasium video on light speed.
