Light

1. Scientific Perspective on Photons and Light

Photons, as massless particles, travel at the speed of light (c) and experience no proper time due to extreme time dilation—from emission to absorption, their journey is instantaneous in their "frame," though no valid rest frame exists for photons. This aligns with your example: a photon from the Big Bang ~13.8 billion years ago perceives no temporal passage. Photons are "invisible" until interacting via absorption or scattering, explaining why space (including Olbers' paradox for starlight) appears dark without obstruction. Einstein's E=mc² reveals mass-energy equivalence, where photons carry relativistic energy despite zero rest mass. reddit

The graph illustrates time dilation approaching infinity as speed nears c, underscoring why photons transcend time.

2. Light in Atiyoga (Dzogchen)

In Atiyoga (highest Dzogchen class), clear light ('od gsal) symbolizes the nature of mind or rigpa—innate, empty luminosity free of concepts, manifesting as thödgal visions (e.g., five lights, rainbows). Longchenpa describes it as "brilliant emptiness," where appearances arise like reflections in a pellucid lake, unconfined and seamless; samsara/nirvana dissolve into this child-mother clear light union. Light evokes unsubstantiality: self-illuminating, intangible, like rigpa beyond inside/outside. Thödgal (sky-gazing, light refraction) reveals five primordial wisdom lights, reversing "corruptions" (elements as solidity). thedaobums

3. Fascinating Parallels (with Caution)

Your insight connects physics' timeless, interaction-dependent light to Atiyoga's clear light as ever-present yet unseen without rigpa recognition—much like photons filling dark skies. E=mc²'s energy-mass unity echoes Dzogchen's luminous emptiness (energy-like radiance from empty ground). Nagarjuna/'s light analogies (self-illuminating voidness) loosely parallel photon self-propagation, but traditions predate/avoid direct science mapping. Track loosely, as you note—poetic resonance, not equivalence. reddit

Key Takeaways

Photons embody timeless, massless light scientifically; clear light mirrors this in Dzogchen as rigpa's radiance. reddit
Both traditions highlight light's subtlety: invisible/unmanifest until "hitting" awareness/matter.
Intriguing overlap with Longchenpa's natural perfection, but mystical, not empirical.
