Yup...

Lil refresher:

Chuck Missler on light:

"you know if you take you start studying the attributes of God you can come up with a number of things he's obviously infinite located at infinity or however you want to express that he obviously is capable of infinite power right he represents omnipresence he can be anywhere all the time he also is omniscient he knows everything anyone have a problem with that good okay it's interesting that light has properties analogous to those"

 "it's located at Infinity light has a velocity limit but it's limited by the intrinsic physics of the universe it's also omnipresent it turns out they've also discovered we'll talk about this next time photons lack locality they've discovered that all photons in the universe know what the other photons are doing."

"...light is the fundamental revelatory mechanism it's the primary way we reveal things because when the light comes on we can see and we can understand and so it it fits the attributes of God it's interesting that in James 1:17 it's every good gift and every perfect gift is from above and comes down from the Father of Lights with whom is no variables nor shadow."

Ask Ethan: Does light really live forever?

(my buddy Ethan Siegal :-).

"In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?"

"In the expanding Universe, for billions upon billions of years, the photon seems to be one of the very few particles that has an apparently infinite lifetime. Photons are the quanta that compose light, and in the absence of any other interactions that force them to change their properties, are eternally stable, with no hint that they would transmute into any other particle. But how well do we know this to be true, and what evidence can we point to in order to determine their stability? It’s a fascinating question that pushes us right to the limits of what we can scientifically observe and measure."

"One of the most enduring ideas in all the Universe is that everything that exists now will someday see its existence come to an end. The stars, galaxies, and even the black holes that occupy the space in our Universe will all some day burn out, fade away, and otherwise decay, leaving what we think of as a “heat death” state: where no more energy can possibly be extracted, in any way, from a uniform, maximum entropy, equilibrium state. But, perhaps, there are exceptions to this general rule, and some things will truly live on forever."

"All of the electromagnetic radiation that exists in the Universe is made up of photons, and photons, as far as we can tell, have an infinite lifetime."

"Even at its very end, no matter how far into the future we go, the Universe will always continue to produce radiation, ensuring that it will never reach absolute zero, that it will always contain photons, and that even at the lowest energies it will ever reach, there ought to be nothing else for the photon to decay or transition into. Although the energy density of the Universe will continue to drop as the Universe expands, and the energy inherent to any individual photon will continue to drop as time ticks onward and onward into the future, there will never be anything “more fundamental” that they transition into."

"But if all we have is the photon as we understand it in the Standard Model, then the photon is truly stable. A Universe filled with dark energy ensures, even as the photons that exist today redshift to arbitrarily low energies, that new ones will always get created, leading to a Universe with a finite and positive photon number and photon energy density at all times. We can only be certain of the rules to the extent that we’ve measured them, but unless there’s a big piece of the puzzle missing that we simply haven’t uncovered yet, we can count on the fact that photons might fade away, but they’ll never truly die.
