True. 13-billion-year-old photons from the cosmic static do not decay, though they may lose energy. If we to able capture a coherent "snapshot" in time, it would still look as it did when it existed.
-
True. Time dilates as particles approach light speed. At light speed, the particle is frozen in time.
-
True. Something with no mass has no weight so therefore does not exist. If something has no mass it does not exist. Even the soul of a person has a mass of 21 mg.

bostjan the adequate 🥉 That's the worst logic I've ever seen come from an adult. Please try again, but this time put some thought into your answer! -
Thinker What part of my double stated comment don't you understand?

bostjan the adequate 🥉 Thinker: "Something with no mass has no weight [sic] so therefore does not exist. If something has no mass [sic] it does not exist. Even the soul of a person has a mass of 21 mg." You clearly have no clue what you are talking about. Light has no mass, but you can see it. Does it not exist to you? If the requisite for existence is having weight, then I guess no object isolated from a gravitational field exists, either, or do you not believe in gravitational fields, either, since those don't have mass. And, as for the soul of a person, I assume you are referring to MacDougall's experiment, which was understood by the scientific and religious communities both to be bullshit even as it was performed. MacDougall weighed six patients before and after death, and *one* of them lost 21 grams. The other five did not. He concluded that the human soul weighs 21 grams, and gave no explanation as to why the other five patients didn't lose weight. It makes no sense, just like your conjecture that stating the same bullshit two times without looking anything up somehow makes you either clear or correct in what you are stating.

Thinker Linda your repeating of your twisting of what I said one time is exactly why I left here for over 6 months so knock it off.

True, if they don't exist they don't experience time.

Who said they didn't exist? Photons and gluons exist!

Three things are needed for something to exist. Space, time and mass.

Massless particles exist - photons, gluons -

They have relativistic mass. (from what I've heard). In order to anything to "be," you need those three things. You have to have some "thing" (mass), you have to have a place to put it (space) and you have to know when to put it (time). -

Yup. That doesn't change what I said, though. -

No, Linda's right. It's well-accepted in physics that particles with literally zero mass exist. Not only exist: but are (sometimes) visible, are detectable, and interact with "massed" particles in our Universe.

True, photons are massless particles which carry the force of energy. For particles time exists in a state of quantum superposition. Ie a trillion centuries would be like zero elapsed time for a photon.
-
Inanimate objects don't experience anything. And humans are the only ones that experience time - the concept of time is relevant only to them.

I like Mr Katt's answer...but still, whether or not a photon "experiences" time, a photon DOES EXIST THROUGH time. Thus (for example), examining a particular photon that is moving through space, we can say at one point in time "that photon is at point A, not at point B" and at ANOTHER point in time "that photon is at point B, not at point A". In other words: it TAKES TIME for the photon to travel a distance. So: whether or not the photon EXPERIENCES time, the photon is certainly SUBJECT to time, in some ways subject to time in exactly the same ways as massed particles.

A photon exists through the flow of elapsing time but not likely possess the conscious awareness to experience the feel of time passing.
