    A hypothetical, probably silly question that has troubled me lately.

    If one were to build a perfectly spherical structure large enough to stand inside, and the inner walls were mirrors, what would the view be from inside if you were to light a match? If the light were unable to escape, would the entire surface shine with the intensity of the flame? Where would the light go when the flame went out? What would your reflection look like in such a mirror?

    Thanks

    I thought about unclosing light is a fixed space, but in reality that's impossible. As for the mirorred sphere, you can find answers perhaps at the hall of mirrors in the fun house.

    Well, we have the benefit of eyes, yes? Reflectivity on our own eyes is how we would "zone-out", yes, of course as animagination? So, how does one zone-out? Place yourself in your own self while seeing the world, while only trying to see yourself. Is this what you are referring to, on a subjective level?

    Is the match in the exact center of the sphere, or is your eye in the exact center of the sphere? If the match is considered as a point source in the exact center of the sphere, then all the light would be reflected back onto the match, and none would reach your eye, except that which is coming in a direct path from the match. When the match burns out, the light reflects back and forth forever (assuming perfect reflection off the mirror), except that which strikes your body and is absorbed either in your retina or some other body part. Eventually, you would see complete darkness, because you cannot see the light that is bouncing back and forth forever, and your body has absorbed the rest of it.

    Except, the match is not really a point source, so the light coming from the edge of the flame misses the center and is reflected from the opposite side. As you are standing near the match, the light going in a path directly away from you would be reflected off the opposite wall and strike your body, being absorbed by your body. The light which misses your body, but is slightly off center, would be reflected off the wall off center, would miss the center of the match, and reflect off the wall. On its next rebound it would miss the center, and miss by a little bit more each time, until finally it hits your body and gets absorbed.

    Babinki, I think you must be a bit zoned out yourself. What drugs are you taking?

    I was responding to the question. Ask me an intelligent one then.
