It's entirely related to what you said. You can't see it because you don't actually know what you're talking about.>when DNA does not absorb visible light much less radio waves
What does that have to do with anything? Why are you so stuck on a direct interaction?
Cells aren't inanimate objects. Think about this. You're typing on a keyboard, how? Your muscles are moving. Are you kidding me? You're expecting me to believe some "electrical signals" from your "brain" traveled to the muscle fiber and then triggered a massive change in the behavior of those cell populations?
Your vision. You're tryin'a tell me, that LOW ENERGY visible light enters the eye, is transduced above a certain threshold, then can trigger a chain of dynamic massive downstream changes in the rest of the body? You're trying to tell me I can alter someone's behavior and global bodily state just by showing them a picture?! RIDICULOUS. Absurd! EVERYONE KNOWS VISIBLE LIGHT HAS POOR PENETRATION DEPTH AND DOESN'T HAVE THE ENERGY TO DO ALL THAT. IT'S IMPOSSIBLE.
Unless you have... uh, transduction and amplification. Because cells are programmable self replicating self powering machinery, that can leverage their own energy production and metabolic ability to "amplify" incoming signals in the character of their response.>>10377089
