| Jul 25, 2016 at 2:39 | comment | added | peterh | @devhl It is also very useful to read the old posts of big names here. It is also very useful if you buy some QM, SR, GR books, most Universities have some specific book store dedicated for them. Learning them makes very enjoyable that you don't need to pass exams from them. :-) Unfortunately, wikipedia is not so good, because it continously uses terms whose meaning it forgets to explain. | |
| Jul 25, 2016 at 2:30 | comment | added | peterh | @devhl Huhh, it is too phylosophical to me. I only played with the math of the SR and the QM on an enthusiast level. This is what I suggest also to you, despite the common concept, only to understand what the formulas say is not so hard as it seems. The main problem as enthusiasts with glowing eyes are talking with scientists, that the enthusiasts are using (and thinking in) phylosophical terms, while the scientists see what it means on the language of the formulas. | |
| Jul 25, 2016 at 2:24 | comment | added | devhl | If they do not experience time or distance, then the action at a distance is explained, as well as the delayed choice slit experiment. It seems too elegant to not be true. In fact, I wondered if Einstein himself thought of this as an answer. | |
| Jul 25, 2016 at 2:19 | comment | added | peterh | @devhl Here I've wrote an answer to somebody saying that the length of the photon is zero because of the length contraction. | |
| Jul 25, 2016 at 2:16 | comment | added | peterh | @devhl I think you feel it well, but every theory is only an approximation and has its limits. On my opinion, your thoughts reached the limits of the Special Relativity and hit the barrier to the QFT (quantum field theory). :-) | |
| Jul 25, 2016 at 2:06 | comment | added | devhl | Since photons have no mass, isn't it a moot point that the mass dilation is undefined? I still feel like there should be time dilation involved to the most extreme. | |
| Jul 25, 2016 at 1:58 | comment | added | peterh | It is not so bad, the problem is that there are no such easy formulas in the QFT as in the SR. But understanding them on a basic level is not so hard if you know derivation of many-dimensional functions, and complex numbers, and matrices. | |
| Jul 25, 2016 at 1:49 | comment | added | peterh | @devhl Yes as you near $c$, the time dilation nears to $0$. But the same formulas would also show that the mass of the photon is $\frac{0}{0}$. Btw, photons are microscopic things and their formulas aren't so easy and beautiful. Quantumelectrodynamics plays with them. In it, the photons are described as the "waves" of a quantum field, and these waves are propagating with c. | |
| Jul 25, 2016 at 1:37 | comment | added | devhl | As an object moves closer to c, time slows down; so why is it that at c the time dilation suddenly stops? It seems like the formula was only written for matter with mass. Perhaps matter without mass has different formulas. | |
