How about a flashdark?

Wouldn't it be cool to have the opposite of a flashlight, a handheld flashdark, that you could use to selectively point and create darkness? It would have to use some as yet unknown, to me at least, particle or wave that would absorb light. Maybe physicists could chime in. The only thing I'm aware of that does this is the gravitational pull of black holes, but a handheld black hole generator wouldn't be terribly safe! I was just thinking how useful something like that would be.....I'll bet the miliatry would enjoy such a tool too.

mm, light can cancel out light.. just need the placement juuuuuusssst right

I saw one of those in a Dr. Suess book a long time ago.

At first I thought the title said "flashdork". Figured I better chime in.

LOL flashdork.

I could imagine in a very controlled setting being able to direct a single photon to "intercept" another, but on a larger scale....no way no how....to much empty space.

You may be a candidate for promoting The Dark Sucker Theory

There used to be a sign on the door at the campus photo lab:

"Darkroom -- Do Not Open Door (You'll Let All The Dark Out)."

I know of at least one other person who probably likes the idea of a flashdark (whatever the term means to him).

There is an illuminated member!
