If you tell me the time of exposure and the mass of the bike and the man, I can tell you the momentum... (nice analogy by the way puppy)
What is an inertial frame and why all electrons have the same properties? Something is missing in the GR-SR picture...
I agree that the time of exposure is critical in the photo of the cyclist.
In the photo, the cyclist looks sharp, and the background blurred. But isn't this only because the photo was taken with a relatively long exposure-time, perhaps 1/500th sec?
Suppose the exposure-time had been much shorter, say, 1/500,000th sec. Then wouldn't both the cyclist, and the background, look equally sharp.
Would that prove anything.
