An analogy they repeat three times. And its just plain false every time. In fact, I'm not sure at all what the analogy is supposed to help us understand. We're not seeing a photon as it moves through space; so why say we are? We're seeing light reflected off of an object; what makes this different from any other camera that does the same thing? Its faster? Then say something to help me understand how that changes things.
We're seeing the way a pulse of photons move through space. So you can see how long it takes for a photon to diffuse through a plastic bottle. You can't see that with other cameras.
