2nd Law of Thermodynamics question

[Crazy Tosser]

I stand on the outermost planet orbiting the outermost star of the outermost galaxy of our universe. I turn on my flash-light and I can be sure that the beam of light will not hit any object. After I turn it on, I cannot recover the photons or prove they ever existed, so does it mean I decreased the entropy of the universe, in a sense? 2nd law violation?

Nah, the entropy of the universe still increased as the energy in the battery used to power your flashlight was dissipated as heat.

I stand on the outermost planet orbiting the outermost star of the outermost galaxy of our universe. I turn on my flash-light and I can be sure that the beam of light will not hit any object.

If the universe has no boundary, then this experiment may be impossible. Not completely sure though. See http://en.wikipedia.org/wiki/Shape_of_the_Universe#Local_geometry_.28spatial_curvature.29".

After I turn it on, I cannot recover the photons or prove they ever existed, so does it mean I decreased the entropy of the universe, in a sense? 2nd law violation?

This scenario is very similar to the problem of http://en.wikipedia.org/wiki/Holographic_principle#Black_Hole_entropy".
