Mass causes light to follow a curved path, but it does not slow down. --- End quote --- Its difficult to know what Einstein meant some of the time, ie re orbits being real, or just a trick of the warping of spacetime. I think that Einstein would say that the light goes straight, but that spacetime warps or bends or somesuch. Anyhow, Shapiro proved that light does indeed slow when passing the Sun (now called Shapiro Delay). I rate this as being Einstein's only real contribution to science, albeit a lucky outcome (his reasoning was faulty)(me myself i came up with the correct explanation). But, if u are correct, then Shapiro Delay falsifies GTR. Which leads us to the proper explanation of why the bending of light passing the Sun is twice the Newtonian bending. But anyhow Einstein helped me to come up with my new (elekton) electricity. His slowing of light is what makes the elekton hug the wire (together with charge attraction). |

--- Quote from: HuronKing on April 04, 2022, 11:10:28 pm ---Cathode-ray-tube televisions are particle accelerators. They wouldn't work properly without special relativity. Jefimenko's papers are fun (because it seems he's mostly bitching about pedagogy) but he points the way to Jackson who makes it clear what Purcell and others are saying: https://archive.org/details/ClassicalElectrodynamics2nd/page/n605/mode/2up I kind of laughed when Jackson wrote, "But what if there had been a magnetic field B' in K'?" So to be clear, Jackson, cited by Jefimenko, isn't taking issue with the relativistic transformation of the E-field from moving charges causing the appearance of B-field effects in the other reference frame, he just wants you to know that it can't be a complete description of the B-field in other reference frame unless you say so... Of course the relativistic transformation of the E-field is not a complete description of the B-field in the other reference frame if that other reference frame already had a B-field from some other source... you'd have to account for that too. Duh? And Jackson delves into this further in homework problem 12.3 (where he calls this a pseudomagnetic force). And even, to his credit, the Science Asylum video that says the magnetic force does not exist specifically addresses the problem Jefimenko was mad about - that one could argue the Electric Force does not exist either. And that's exactly it - they're not independent entities. They're both representations of the total electromagnetic field. And this is what makes aetherists cowardly hacks as Steinmetz warned us about. An aetherist can spend weeks on an EE forum getting personalized counseling from numerous experts after having been banned from multiple physics forums, yet still have no idea what anyone is talking about regarding EM fields Exemplified by saying stupid shit like --- Quote ---I don’t know what STR predicts re fast moving electrons. --- End quote --- My God, that's STR 101... --- End quote --- CRTs don’t need relativity. GPS duznt need relativity. One problem with STR explaining mmf, is that after it explains the mmf, there is still nearly 100% of the mmf (lets call it B') sitting there in parallel with the non-mmf. But, there is no way that B' can contribute any mmf (according to STR). What a disaster. E=mcc is not a part of STR. STR duznt even lead to E=mcc. If indeed mass duz increase with speed then it will need a proper explanation, not some silly STR or spacetime explanation. Aether theory says that mass is the property of photons & elementary particles (eg electrons)(confined photons)(everything is photons)(everything has mass) whereby they annihilate aether, & aether flows in to replace the lost aether, the acceleration of the inflow whereby the streamlines converge in 3 dimensions giving us the well known 1/RR relationship. Hence, if mass increases with speed (which aether theory duz not rule out) then that would require that speed increases the rate of annihilation. But i doubt that (real) mass increases with speed. Apparent (non-real) mass might increase. But for sure spacetime (ticking dilation)(length contraction) has zero to do with mass. Aether theory prefers that there is only one real mass, in effect the rest mass, & that this never changes. But, if it duz change with speed, then aether theory will have to accept that, but it would then have to try to come up with an explanation. |

You just said you don't know what happens when an electron goes very fast, or at least, what STR says about it. You ignored this in the other thread. You'll ignore it again, I'm sure.

We don’t know what electricity is, but there are a lot of electric designers out there getting paid good money. Time dilation in STR is due to the silly gedanken way of synchronising clocks using light & mirrors. If Einstein synchronised his gedanken clocks by using sensible slow transport then silly STR & silly time dilation would not have been needed. However, what we do have is ticking dilation, where all clocks of all kinds are affected in varying degrees by speed (ie the speed of the aetherwind), & also in varying degrees by the nearness of mass. Anyhow, i am still waiting for u to explain to me how STR can help B' to make an mmf (ie having already used STR to make an mmf from B). No hurry. |
