Not convinced.
Has Light got a decay factor?
Sort:
I had a good question....but I just 4got it....shat !
damn...I had a good answer
Okay. Tell me ur answer and then I'll tell u my ?....'cuz now I remember what I was gonna ask.
Then we'll see how they match up. Could be hilarious !!
The Answer to Lolas question -:
Even though the Earth has been in motion for 4.5 Billion years and shows no sign of stopping it can't be considered an example of Perpetual Motion.
My question was....if I hyperflashed a flashlight (to make a 3" round by 24-inch long cylinder of white light) in a 20 ft x 20 ft x 20 ft cube room made of mirrors, would the mirrors absorb the light right away ? If not ?....what would it look like in there ? Would there be dark places ?
....so we're kinda thinking together here. 
two manifestations of infinity... how cool is that..
Matter is made of fundamental particles and if those particles have been thrown into space due to the extreme heat of the continual nuclear exploding sun what happens to them in the depths of cold space? Do they coalesce and huddle together for warmth or are they permanently fragmented?
It's probably the case that fundamental particles naturally come together to form more complex structures. But how? The Higgs Boson is supposed to be part of the process.
I ask 'cuz I wanna know where the cylinder of light gets & maintains its energy to keeping bouncing around the mirrored room....time infinite. Oh well....nvm.

The light never leaves the room so no energy is lost so no need to input any and as light never decays ((((APPARENTLY))) it should go on indefinitely. However there is a problem with that. Every time the photons bounce off a mirror they must impart some of their energy to the mirror there by losing energy. But how can it lose energy if it never leaves the room? I guess some of the energy is transposed to kinetic /potential energy. So it does leave the room after all but by another form of energy! Simples.
But I thot EVERYTHING lost energy over time....
....remember Sippy Bird ?
....and pleez don't gimme that look.
Just had a thought experiment (wasn't painful) . Imagine being in said room covered with mirrors ,walls floor ,ceiling . When you turned on the torch you would see countless images stretching out to infinity! But when you turned off the torch would you actually see a kind of explosion of darkness happen all around you in every direction. Probably to quick for the eye to see but it would be so cool if you could because then you would actually see light travelling. A high speed camera would capture the moment of course. It's probably already been done on the net somewhere.

a photon slowed down by a trillion frame per second camera set up
The amazing thing about that film of a photon is that you can actually see it's shape and why it can be both a wave and a particle at virtually the same time. Einstein would have been so thrilled to see what he imagined revealed in reality.
So take the film w/ the HS camera and then slowmo it down by a trillionth ?....wow !
Btw, I watched the guy talking on the video w/out the sound. It looked like he was someone trying2 talk me n2 something at a carnival or he was just really excited. Either way, almost 10MM hits. So, haven't heard it yet.
