It's not meaningful light that's used in biology.

So what I'm looking into now is, okay, light's being generated from the mitochondria.

Does that light carry some form of information that the cell can use to do what it needs to do?

Is it purposeful and then being utilized by the body?

Yeah.

So I was thinking, okay, we're sitting in a bath of light that's coming from this big ball of fire, which we call the sun.

Does this light have any impact on our physiology?

Like, you know, okay, before I understand internal light,

What does external light do?

I see.

You were just like, how are we interacting with external light?

Does any of that apply to the internal light we're making?

The light's the same.

The photon is the same.

For example, there are these proteins called opsins in your eyes that help convert different wavelengths of light that help regulate circadian rhythms.

I guess that makes sense to me because the eyeball is a light element.

Yeah.

I mean, if you go to any literature, the first thing that will come up is vitamin D synthesis.

It's that, okay, the sun...

And it hits your skin and your skin processes vitamin D and, you know, that does a lot of things for metabolism.
