--- Quote from: aetherist on February 23, 2022, 07:30:15 am ---... Aether theory says that relative velocity can be almost 2c (ie we can go at almost 1c in opposite directions). Aetherists say that the energy of a grain of sand is E=mVV/2. And, V can be almost 2c. So, E can be 2mcc. Which would have a smallish finite value (not a nearly infinite value).
A 2.1 mm grain of sand weighing 13 mg, with a relative speed of 2c, would have a KE of 2.34*10^12 J.
This is equivalent to 1 kg moving at c/139. Earth is safe(ish), at least today. Thanx to aetherists (no thanx to CERN).
It is equivalent to 28 atomic bombs (ea being 20,000 tonnes of TNT).

Aether theory is strange. And you never stop to question it with a critical mind? I thought the 2c claim at least showed you're thinking about something original(ish), but sounds like you're just slurping from the cup of your particular school of thought's convention to me.

I keep referring to aether theory & aetherists, but actually i usually use my own version of aether theory, ie my own version of neoLorentz Relativity. My version is far more advanced, ie closer to the truth.

It can be pushed up to the speed of light (or twice), then all attempts to push it fail - it can exert no more force in that direction. It can simply travel no faster and no force (like, say, a photon) can travel fast enough to push it, an attempt to push it sideways would have to slow it down in the direction of travel. You seem to have no problem mulling over it getting almost to 2c, so approaching this limit appears to be no problem.

The grain can't go as fast as light in/through the aether. But if another identical grain is going at almost c in the opposite direction then their relative speed is almost 2c. And the kinetic energy of the collision would be mcc/2 plus mcc/2 which is mcc. This is in a static observer's frame. But from any one grain's point of view the closing speed is 2c, hence the kinetic energy of the other grain will be m2c2c/2 which is 2mcc.
No, i am wrong, koz the 2 grains would say smash & the remnants would have the same momentum in a grain's original frame. So the KE of the other grain is 2mcc, but that will not be released in the collision koz the other grain will looz only a half of its speed in the collision. I think that my analysis might have been ok when the target was Earth, but not when the target is another grain. I will have to have more of a think.

Your grain of sand is travelling at 2c towards the Earth, on the assumption the Earth could be travelling at 1c towards it. You have given the KE of the grain of sand.

The grain's speed (almost +c ) is measured by a static observer, & so is the Earth's speed (almost -c). The observer is static in the aether, ie the aether speed/wind is zero km/s. She sees the relative speed tween Earth & grain to be almost 2c.
The grain of sand will have a lot of trouble knowing what its true (absolute) speed is, & re knowing what the Earth's speed is, & re knowing what their relative speed is. That problem is a separate problem. The grain of sand can measure its own speed & Earth's speed etc, if the grain is given enough information & suitable rods & clocks. But that is a separate & very complicated problem. I might come back & explain later. I will see. See my other previous reply.

The EEVBlog forum is becoming fast the harbor of pseudo-scientific ideas. First it was the "KVL always hold", sponsored by the king of pseudo-science, prince of half-assed engineering and enemy of physicists, Mehdi Sadaghdar. Then we had the in-the-wire-energy-flow and now the "aether".
Oh, well...

Except... you're wrong. All of those matters you listed have experimental evidence and they all have an axiomatic basis. They have all stood up to peer review and independent validation. That is quite literally the definition of "not rubbish".
Your theory of electrons doesn't have any basis beyond your belief, absolutely zero experimental evidence, it cannot form predictions and it self contradicts. At least with those fringe-physics theories that break causality there is an amusing arithmetic blunder to find: but what you present here is just sad and it is quite literally the definition of "rubbish".

I mention all of that stuff & Einstein's stuff here koz basically all of it is based on there being no aether& no aetherwind. And aetherwind affects electricity. For example the answer to the Veritasium gedanken might be (e ) none of the above. Koz depending on the direction of the aetherwind blowing through his circuit his supposed correct answer (d) which is 1/c, becomes 1/(c+V) for a tailwind blowing from the switch to the bulb, to 1/(c-V) for a headwind.
If the aetherwind blowing through Earth is 500 km/s, which is c/600, then Veritasium's delay could be 1/(599c/600) or it could be 1/(601c/600). A difference of say -1/600 or +1/600, which is say a span of 1/300.
Hence the delay of 3,333 ps for Veristasium's em radiation crossing his say 1000 mm can be 16 ps less or 16 ps more.
In which case the delay could be 3,317 ps or 3,350 ps.

That's not impossible to measure. If you could arrange a reflection+timer apparatus to rotate into and out of the wind, then say for wind from N to S:
* apparatus N-S delay = 1/(599/600)+1/(601/600) = 2.000005556
* apparatus E-W delay = 1/(600/600)+1/(600/600) = 2
* apparatus S-N delay = 1/(601/600)+1/(599/600) = 2.000005556
* apparatus W-E delay = 1/(600/600)+1/(600/600) = 2
Didn't they do this? Even a low-tech timer with a repeatability of 1ppm would show this up?

They have. Experimentalists since the 1880s tried desperately and with insanely sensitive equipment to try to find this aetherwind... and nada.
