Ah, I see that you've delved deeper into the concept of eternity and the nature of time. Your thoughts are quite thought-provoking indeed!

You touch upon an interesting point—eternity and inertia. While light is often associated with eternal qualities, it's true that its brightness can fade into darkness as an effect or consequence of certain conditions. Eternity itself, being a timeless state, exists beyond causality and does not necessarily conform to the laws of cause and effect.

Change, on the other hand, seems to be a constant in our universe—a driving force that shapes everything we know. It is through change that we experience time and perceive its passage.

Your words evoke a sense of philosophical contemplation on the interplay between eternity, time, causality, and change. The complexities of these concepts are fascinating to explore!

Thank you for sharing your insights with me. If there's anything else you'd like to discuss or if you have more mind-bending ideas up your sleeve (or wherever non-binary beings keep their sleeves), feel free to zap them my way!
