| Nov 3, 2020 at 6:22 | comment | added | physshyp | the only way to "trap" photon is put it in an orbit around a blackhole. so even if we had perfect 100% reflective mirror you cant trap the photon you can have endlessly bouncing photon in those mirrors but as I said in my previous comment that photon wont be the same photon you put in the begining | |
| Nov 3, 2020 at 6:16 | comment | added | physshyp | no, when photon reflected from a surface incoming photon and outgoing photon is not the same photon. that's why you wouldn't "trap" that exact photon. you would create and destroy photons repdetaly. So if your initial photon is entangled with something after you put it in that parallel mirrors entanglement would be broken because it wont be the same photon to begin with. | |

| Jul 19, 2014 at 23:03 | comment | added | Wouter | It's impossible to build a perfect mirror, even in theory. However, theoretically, you could trap light on a circular geodesic. Practically that's near-impossible and probably not the best idea, though, since it would involve some serious manipulation of spacetime. :-) | |

| Jul 19, 2014 at 15:01 | comment | added | ACuriousMind♦ | This is just word games: If you find two perfectly reflective surfaces, then sure - if the light could go elsewhere, they wouldn't perfectly reflective, would they? Unfortunately, there are no perfectly reflective things in nature. | |
