We have even fought hard to defend your privacy in legal cases; however, we've done it with almost no financial support -- paying out of pocket to continue providing the service. Due to the issues imposed on us by advertisers, we also stopped hosting most ads on the forums many years ago. We hope you appreciate our efforts.

>>> What if you had a sphere, and the inside surface of the sphere was covered by a mirror. You are somehow able to put a flashlight inside the sphere, and turn the light on.
... What eventually happens to the light, since it keeps on being refracted off the mirror?
...Like i said, this isn't a problem, it's just a thought i had. <<<
..... The light uses energy that is supplied by the battery, and that energy is eventually converted into heat, even if the light is reflected many times by the mirror.
..... I once saw a toy oven that had a lightbulb inside, and it could get very hot, although no light was visible from the outside.
