    How fast is ignorance? Atleast faster than most guardian angels... cut off a semi, text and drive, drive too fast on an icy road, using your foot to push the last limb into the tree shredder, swallow a condom or beat a train across the tracks and you'll see exactly how fast ignorance is

    I know this s anIs an old video but I feel he fundamentally misunderstood how shadows work(I am in no way an expert my self). The shadow would move at the speed of light because if you cut off a light source the residual photons would continue to travel towards the light object. Love key a extremely fast tap the if you block the flow the water(photons) under your hand will continue to move until it hits whatever it was pointed at.

    Sometimes I wonder this, if you record a light being turned on in a dark room, and then slowed down the video EXTREMELY slow, would you be able to see the light travel from the lightbulb to the rest of the room in the slowed recording? cause like when you turn on a light you can’t even see the light fill the room cause it’s so fast it just looks like the room is suddenly bright

    Its not traveling faster than the speed of light its just that light itself was blocked a physical object therefor making the light unable to move further...

    Ok, so Michael states that the point of intersection between two objects, like the blades on scissors, move faster than each object itself. If we were able to create two objects that are capable of moving just under the speed of light and then find a way to connect an object to that point of intersection that would move with it, is it theoretically possible to actually match or exceed the light speed barrier? I don't see a way of doing it with dark or shadows, but there's got to be some existing theory about this out there, right? Anyone know what it might be called?
