Some might wonder why I waste time with nonsense. I see it like analyzing perpetual motion machines. Someone presents you a perpetual motion machine - we know it's wrong, but how is it wrong? It's easy to spend lots of time wandering in Simanek's Museum of Unworkable Devices but it'll help sharpen your ability to spot cons, frauds, and crackpots: https://www.lockhaven.edu/~dsimanek/museum/unwork.htm
I don’t know how u got onto perpetual motion machines.
But this latest one...So, the beam of light crossing the elevator consists of horizontal arrows. For an inside observer the beam appears to bend down (the elevator is accelerating up), but the arrows nonetheless remain horizontal (for the inside observer)(& for the outside observer).
There isn't even a coherent description of the elevator thought-experiment here to debunk... the light bends and is straight for the same observer? LoL. So this one doesn't even merit any additional time wasting.
To the inside observer the beam appears to bend down, but the individual photons (arrows) remain horizontal.
To the outside observer all photons (arrows) have a horizontal traject all the time, & all photons (arrows) remain horizontal all the time.
Now I do want to draw attention to this utterly laughable claim,his 1.75 arcsec was a brave prediction, however it was little more than a lucky guess
LoL... ahh yes - Einstein can only be right because he guessed.
I admit the mathematics of Einstein's original paper or any graduate level mathematical textbook of the subject is dense and very, very hard. This is why I am grateful for Epstein and Hewitt's efforts to make this stuff a little less impenetrable (their textbook on Conceptual Physics was mine in high school).
The mathematical derivation of the predicted diffraction here is a little tedious but its not inscrutable for anyone who understands integral calculus:
https://www.relativity.li/en/epstein2/read/i0_en/i2_en
Which is the same result Einstein derived in the 1916 paper and in many other subsequent texts on the subject (McVittie, General Relativity and Cosmology, p241). !
Einstein's derivation was based on the inclination of a wavefront of a ray of light passing say the Sun.
He predicted that the part of the wavefront closer to the Sun would be slowed due to the nearness of the mass of the Sun (i am happy with that)(it accords with his slowing of light near mass postulate)(this postulate was proved correct by Shapiro using radar reflexions from i think Venus in about 1962).
And Einstein says that therefore the wavefront leans as it passes the Sun (i am happy with that).
But then Einstein introduces a hidden postulate, he assumes that the leaning wavefront automatically means that the traject of the parent ray of light bends. No. It might bend, or it might not. Einstein treats the wavefront as if it is refracted when meeting an inclined pane of say glass. But Einstein fails to explain this assumption, ie this postulate. And he fails to provide a reason why the traject might bend.
If i layed 10 identical panes of glass flat on top of each other on a say table, but the lower panes having a slightly greater refractive index than the higher panes, & if i sent 10 photons into the panes, 1 photon per pane, entering into the edge of each pane, then they would all go straight through to the other end of each pane, & the higher photons would exit before the lower photons. But, all photons would go straight, all the way, there would be no bending of their individual trajects, & there would be no bending of their combined traject, even tho they would in effect give us a kind of leaning wavefront.
Now, if we replaced the 10 panes with an equivalent single pane which had a gradual increase in refractive index from top to bottom, then we would all agree that the 10 photons would all have a bent (curved) trajectory. But Einstein did not explain that in his gedanken the nearness of mass would result in a refraction of the same kind that we know we get when light passes through mass. He should have explained that he was invoking this as a postulate. And then he should have provided good reasons for that postulate. But there was no transparency (pun alert). Now, had he, i would have been happy with that, i mean its his gedanken, he makes the rules. I would have been happy for him to invoke Huyghen's refraction of light in mass, ie to apply it to the refraction of light near mass.
I wonder how Einstein would have explained the bending (curving) of a single solitary photon passing the Sun. He would have no ray to play with. No wavefront to play with. Poor poor Einstein.
To anyone who doesn't understand integral calculus, I suppose this is all just luck to predict *exactly* the right value later observed by experiments. But gee, we seem to get lucky a lot when we use math.
I understand the postulates of integral calculus, but i don’t understand the math & equations.
However as i mentioned the other day i have checked the math for Einstein's bending of light passing the Sun by using Excel & i found that Einstein's postulates did indeed give the correct numbers for bending (ie 0.87 arcsec for the bending of space, & 0.87 arcsec for the bending of time).
But my Excel check did not say anything about Einstein's equation for bending, i didn’t use his equation, i used his postulates.
I would be happy to send a copy of my Excel to anyone who wants, but it might be hard to follow (i probably couldn’t follow it myself today)(i was lazy re explaining what was what & why).
I remember that the difficult part of my Excel was the Huyghens refraction part. I had to use some clever arithmetic to mimic Einstein's integration.
I said that Einstein was lucky. I said that koz i know that the aether inflow in to the Sun gives 0.87 arcsec of bending. I have calculated that using Excel. It is based on the velocity of the aether inflow being exactly the same as the velocity of a particle falling to the Sun. Hence aetherists can calculate the velocity of the aether inflow at any location by simply using Newton's equation for escape velocity. In effect the aether inflow bending is the same as the bending of Poor's falling particle.
Einstein used the escape velocity in his equation for the slowing of light near mass. He inserted that V into his equation for his gamma in his equation for length contraction, to get his radial component for the space part of his bending. And he inserted that V into his equation for his gamma in his equation for time dilation, to get the time part of his bending. Just a little reminder here that the time part is a scalar, whilst the space part is a vector (probably not important today).
If my aetheric bending (0.87 arcsec) is true, & if Einstein's bending (1.75 arcsec) is true, then the total bending should be 2.62 arcsec, which is 0.87 arcsec too great. If the aetheric bending is correct then the Einsteinian bending should be only 0.87 arcsec. I assume that slowing gives 0.87 arcsec, plus my aetheric 0.87 arcsec gives 1.75 arcsec. If i am correct then this leads me to say that Einstein was lucky, he got the correct answer using wrong reasoning.
