What it concludes

Lights do not take any noticeable time to go out in a mirror room because the speed of light is 300,000 meters per second.
Mirrors only reflect about 95% of visible light, causing reflections to become dimmer and eventually fade away after about 16 reflections.
A mirror room exhibits Gabriel's Horn mathematical phenomenon where the volume of reflections is finite, but the surface area is infinite.
