well, yeah, let's assume that we and the torch would be mirrors lol
even if we weren't there still would be light at all times in the other points of the room. saying that we would absorve the light there doesn't make much sense, otherwise i could say i was absorbing light that is miles and miles away.but i'm not as dense as a black hole to be able to do that..so i wouldn't be able to even atract light that was in the same room. i would absorb light that is targeted at me, but not light that is near me (i think?)
anyways, the question here (@ percy) is, why would light dissipate in the first place?
what you said in your other post, i think you're talking about how light bulbs work?a lot of energy goes through the electric resistance causing it to heat and therefore it becomes bright and produces light?but light is already the energy that comes out of it, not the heating and the resistance itself.
however, the fact that when you have something going so fast (or with a lot of energy) make something brighter works like sounds (if you of course adapt your thinking. in acoustics, sound (as in notes) are made of incredibly fast and repeated beats. if you make an electronic device sound a beat per second, you'll hear a beat. make it sound two, you'll hear two. make it sound four, etc etc..when you make it sound like 32 and you'll hear something really low. make it sound incredibly fast beats (hundreds per second) and you'll hear notes (the more beats per second, the higher the note), you know, frequency, hertz
