| Jun 12, 2014 at 18:52 | comment | added | anna v | @CountIblis general relativity is in the proof, lorenz invariance needs flat space locally | |
| Jun 12, 2014 at 18:45 | comment | added | Count Iblis | This is about the photon collapsing into a black hole. The energy of a photon depends on the reference frame, the energy momentum four vector transforms according to the Lorentz transformation. | |
| Jun 12, 2014 at 18:42 | comment | added | Hakim | @CountIblis Could you expand on it a bit more? | |
| Jun 12, 2014 at 18:34 | comment | added | Count Iblis | This seems to violate Lorentz invariance. | |
| Jun 12, 2014 at 18:27 | comment | added | anna v | It is not my claim. There is a proof in the link, it is a single photon that they show will form a black hole | |
| Jun 12, 2014 at 18:25 | comment | added | Hakim | @annav Since photons are a form of energy then using your claim a photon will become a kugelblitz, which is AFAIK highly hypothetical. | |
| Jun 12, 2014 at 18:20 | comment | added | anna v | There is a claim in the entry in wikipedia en.wikipedia.org/wiki/Plank_length that a photon with wavelength the plank length would become a black hole, which excludes photons with smaller wavelength . cannot check the proof | |
| Jun 12, 2014 at 18:15 | comment | added | Zo the Relativist | And of course, there's the problems with extending the notion of "photon" out of the realm of applicability of the standard model, and the idea that the planck length isn't necessarily the smallest possible length, but just the length scale on which you would expect quantum gravitational effects to become dominant, and within which we can't really do physics without quantum gravity. | |

| Jun 12, 2014 at 18:13 | comment | added | Zo the Relativist | We certainly have not detected any light with a wavelength as short as planck's length. The highest energy photon detected is something like $10^{17}$ eV, which corresponds to a wavelength of $10^{-25}$ m, which is still much a factor of ten larger than the planck length. | |

| Jun 12, 2014 at 18:07 | comment | added | user26143 | I may be wrong, I guess except in some discrete space approach which contains minimum length scale, Planck length is not the smallest possible wavelength. | |
