Why can't we overtake the speed of light

I have an interesting question. Assume you are in a room covered in mirrors (all walls, floor, ceiling). You yourself are covered in a material that is 100% reflective (the mirrors are also 100% reflective). In the perfectly reflective room, you strike a match. Assuming your body, the match, and the mirrors do not absorb light and only reflect it, would the room stay lit long after the match went out? Would there be a limit on how bright it would be inside the room?

Your eyes would absorb photons in order to see them, so, do you want to go into "if you light a match in a perfectly mirrored room, but nobody is there to see it, is it lit up"? :P

Also, any gas in the room would also attenuate the light fairly quickly.

I am aware eyes absorb light. Just assume no person is in the room.

Okay well the atmosphere in the room absorbs it then, if you had perfect vacuum, then the brightness in the room would be proportional to the amount of time you left the match lit for as long as forever.

Would it keep getting brighter and brighter, with no limit?

Social Ecology Eclectic : Light exceeds its own speed limit, or does it?

Yes, I did mention this earlier in the thread. There is no evidence that information can be transferred faster than light using this method.
