No, Bob, there's absolutely nothing to worry about. This is just like shining a light on you. Light isn't material, so it can't hurt your body, can it? That's what us scientists would call "action at a distance," and we don't believe in that anymore, do we, Bill?
Good Heavens, No. There are no "right" or "wrong" answers here, Bob. Don't worry about that. Set aside your outmoded metaphysics. We're scientists here. ... There are only answers that result in varying degrees of pain for you and your family.
