If this wasn't TED, I'd call BS. Instead, I'm just confused.
Light is very fast. Very fast. I would like to know how the camera works so that you can see light moving. It seems to me that the camera has to function faster than the speed of light to capture the light like that. (Maybe I'm wrong about that, though.) The electricity moving around on the circuit boards inside the camera is only traveling at the speed of light.
He said something about taking multiple exposures to gather enough light to put this together. So is this not actually showing a single pulse of light, but multiple pulses combined electronically? If that's the case, then I can sort of understand it, but I really don't understand how it works. Instead of talking about the images produced, I wish he talked more about how the camera worked. Then I'd believe him. But this is TED, and I've always trusted TED. Hmm.
