We see stars as they were billions of years ago by gathering far spread out and far travel light photons? true, witness Hubble & Vast Array Telescopes in several different bands of Electro Magnetic Spectrum
If so is there a point were the photon would break down and disipate?Yes, at the Event Horizon of (theoretical) Black Hole
DOes light go on for eternity albiet scattered so far apart that it is not detectible?Yes, AND with a large enough LENS (eyeball)...say Galaxy size...the very early universe would appear sharper/clearer/ distinct
Does light age?No, & neither do radio, microwave, gamma ray, etc etc etc...as they are energies

There are such things as stupid questions. Light is the byproduct of a chemical reaction for crying out loud.

Check out the life cycle of a star.

I don't understand. This is also a stupid question, that is phrased in such a way that it has no answer.

no, no
PS This thread is pointless.

The answer is yes, photon moving through uniform vacuum of space at the speed of life is timeless, for time stops! A photon that has travelled billions of light years would arrive at a destination where those billions of light years passed by, but the photon would have not 'aged' a second.
Caveat emptor, space is full of gasses, masses, other energies (ie, gamma rays), and GRAVITY.
Gravity can dilate time for photons, though, as it bends, distort, even slow down the speed of light (ie, black hole)
Not sure how much maximum, gravity can accelerate the speed of light/photons, though. Anyone knows the upper limit beyond the "speed of light"? For photons, or any atom/ic particle of measurable or greater mass.

Of there is no ticking of time for light then can be said to be timeless in the strict sense of the word. Time is relative which is why we see light. We are on a different timeline to the photons we are seeing. For a photon witnessing human existence one must assume our time flys by at the speed of light also.

That's a cool thought,
Does anyone really know for sure if a photon won't run out of energy or fizzle out eventually though? We've only seen 13 billion year old photons. In theory I suppose they wouldn't, but no one has seen a trillion lightyear-old photon before.
