this is a purely theoretical thing, please don't roast me over the illogicalities of it
Supposing we have a light source in a box where all the walls are total mirrors and will reflect ALL electromagnetic radiation (heat, light etc etc)
if we shut off the light and assume the bulb or whatever will absorb nothing what will happen? I was thinking that theoretically the light would continue to bounce around
now assuming the light did continue to bounce around (because theres no way out after all) what would you see if you could somehow look into the box without loosing the light?
assuming the light continued, if you compressed the box would the light intensify?, I know light has no mass but it would have less space to move essentially meaning it increases and Finally, if you could compress the box containing the light to diameters of 200nm X 200nm (the wavelength of light in this case) what would happen? would the light stop? could we transform light into matter by stopping it from moving?
