HA! I just had to explain why you couldn't do this to a student. He wasn't getting it so I just told him to keep trying and let me know if it worked. |

Obviously it's not humanly possible, but theoretically, why can't you do this? |

| moving anything faster than the speed of light is impossible. But, removing that issue I am sadly not entirely sure. Wouldn't the photon's cancel each other out? I keep thinking about the slot experiment which demonstrates wave interference as major argument against this working, but thankfully the kid was only a second grader and I just had to pat him on the head and move on to the kid jamming things up his nose. |

OMG! That seriously had me cracking up. I envisioned him getting rather defensive and saying this... especially farturator, seriously. Then I busted up laughing.

1. You couldn't do this because (and physicists please correct me/fix for accuracy) accelerating to the speed of light would cause the mirror's mass to become infinite. Thus there would not be enough energy in the universe to make it move at such speed.
2. Every single form of energy at some point turns into heat. So suppose you had this experiment set up somehow, the light energy would cause heating of the system in some way and thus would dissipate over time. |

| just because heat is being released doesn't necessarily mean that the heat would build indefinitely. |

The light would cause heat no matter what. Light converts to heat, the heat dissipates and the energy in the system fades. |

I might be easier to imagine two absolute reflective mirrors, one 'light minute' apart, that are perfectly parallel (and about to be opposite) to each other. If you fire a photon perpendicular to one mirror and then move the other mirror into place within one minute (as seen in the lol diagram), then providing there is no disturbance between the two reflective surfaces, you'll have 'endless reflecting light'.
But this of course, has absolutely no use at all (as far as I can tell).
If you add more photons, then you may get interference, yes, they may possibly appear as standing waves, but the waves themselves will still be propagating.
Kudos on remembering Youngs Two SLIT experiment, but that demonstrates properties of light that have no significant consequence on the theoretical situation we're discussing. |

Light won't last forever though as it will be converted to heat. |

In the situation described, we are talking about two perfectly reflective surfaces, with no disturbances between them. This obviously isn't practically applicable, but if it was, then how would the light quanta transfer it's energy into heat? |

| if two mirrors resonate the light absolutely perfectly for long enough wouldn't most particles eventually interfere with one another? And, nobody is entirely sure if a photon will travel indefinitely even without gravitational interference. |

The two 'mirrors' wouldn't 'resonate' the waves of light, but if there were many light quanta being reflected, then yes, they probably would interfere, in which case I refer you to my previous post.
As for gravitational interference, it's already been proven that space-time curvature effects the trajectory of light waves. But by bringing this up, you're destroying one of the initial boundary conditions I set up, i.e. no disturbances between reflections. Anyway, we're sure light will travel the same speed in all frames of reference, irrespective of gravitational conditions.
I like you're thinking, though. |
