I read that in a science article, the same the general public reads. I assumed they actually measured it. That is the problem for me, one article says one thing and another contradicts it. I know that is science, but it hard for me to know what is what, or even tell a difference.
When it hits an atom, the photon is absorbed into the atom and that energy is transferred to the electron which jumps into a Higher Energy State. The photon has ceased to exist. It is either moving at "c" or it is not in existence.
This is my attempt to argue, the best I can do. Does the photon lose all its energy? How can we be sure? Based on what you wrote about absolute zero, something should remain to keep the photon in existence, or that may be possible, if not required.
I have thought about this question, but I do not know the answer.
Light enters the water and bends; the photon only goes down so deep then changes. What affects the photons to change and what happens to them next?
A thing popping into and out of existence defies the universe recycling. How can the universe recycle empty or none?
I know that is not what you mean based on the car example. But still, one minus one claims otherwise.
