| Aug 26, 2015 at 12:42 | comment | added | gbjbaanb | @annav sorry, Einstein didn't like it either... but it turns out Bohr was right and Albert was wrong here. Quantum particles do not behave like 'real' particles. This has been proven experimentally. What it means is that quantum particles don't really exist :-) | |
| Aug 26, 2015 at 11:19 | comment | added | anna v | @RussellMcMahon You are wrong. There exists an enormous amount of experimental data that agrees with the limit of velocity being c, including the currently running LHC experiments. We are long past the age when one could ruminate and come up with the atomic theory. We have hard numbers now. | |
| Aug 26, 2015 at 11:13 | comment | added | Russell McMahon | @annav Nothing we know of certainly :-). Plug in velocities > c and see what happens to energy as speed increases. | But I had in mind what happens to photons AT c. Plugging things in" to the standard equations, time ceases to 'progress', distance "shrinks" to zero. All photons "see" no time or distance. There IS no time or distance in 'their world'. Long ago I noted a comment by a Physicist that he was unhappy carrying out experiments with 'particles' which were in instantaneous 'communications' wth all others. He at least had come to the same conclusion as my naive layman's picture had. | |

| Aug 26, 2015 at 8:49 | comment | added | Russell McMahon | @CarlWitthoft BUT [ :-) ] all photons are in instantaneous 'communication' with all other photons and "stationary" (or infinitely "fast")(d/t as d->0 and t->0 =?) as they reside in timeless and "spaceless" eternity in arguably total darkness and/or total light and ... . [How many photons can dance on the head of a pin ... ?] | |
| Aug 25, 2015 at 12:14 | comment | added | Carl Witthoft | @Luaan Given that such a putative entanglement is of the order maybe $\frac{1}{c^{10}}$ I wouldn't really worry about it. :-) | |
| Aug 25, 2015 at 11:53 | comment | added | Luaan | @CarlWitthoft And eventually, you get to the point that the brain is entangled with the whole world it observes, including the stars thousands of light years away. Somewhat mindboggling. | |
