| Jan 18, 2015 at 10:59 | comment | added | MSalters | A related question is of course how such a photon would be created. There may be photons who can only be created in conditions where the energy concentrations are so high that the region of space is inside the event horizon of a black hole. | |

| Jan 17, 2015 at 15:58 | comment | added | Hypnosifl | @HDE 226868 - ACuriousMind was just saying the Planck length has no special significance in current quantum field theories, which are incompatible with general relativity - most physicists working on quantum gravity would probably bet that it will be very important in such a theory, though I don't know (and ACuriousMind didn't address) what current attempts at such a theory like superstring theory would say about the implications for the energy of individual photons. | |

| Jan 17, 2015 at 15:08 | comment | added | Hritik Narayan | Its supposed to be the base unit for length in the system of units created by Planck. The value of the Planck Length is derived from h, c and G, which are assumed to be fundamental constants of the universe. math.ucr.edu/home/baez/planck/node2.html you should read this. If the mass of something is the Planck mass, then its Schwarzchild Radius is equal to its De Broglie Wavelength. | |
| Jan 17, 2015 at 15:08 | comment | added | HDE 226868 | See ACuriousMind's answer here. The Planck length isn't that important. | |
| Jan 17, 2015 at 15:01 | comment | added | Sofia | very interesting! I heard about Plank length but never paid attention. I even don't remember in which connection I heard of it. Can you tell me what is Plank length? | |
