Does a photon experience distance or time?
No, photons are sentient and don't "experience" anything.
or... Does it simply jump from atom to atom instantaneously millions or billions of light years away?
Photons do not require a medium for travel. Therefore, they do not "jump from atom to atom"
From a photons point of view, does it really travel anywhere?
A tree that falls in the woods does indeed make a sound, so yes.
Some experiments show that light doesn't exist unless we look at it.
Reddit threads don't count as experiments.
