Rescuing Reality
A "retrocausal" rewrite of physics, in which influences from the future can affect the past, could solve some quantum quandaries—saving Einstein's view of reality along the way.

"Of course, Lorentz' formula "yields results that are independent of direction".

Then you knew that your assertion was flawed: "If Einstein's 'time-dilation' and 'length-contraction' are really observed effects then I am wrong. Maybe you are confusing them with the plausible effect that is named after Christian Doppler."

Of course you probably know my response to the rest of your message except for:

"You wrote: "The Lorentz Transforms should not be applied reciprocally." I...


Of course, Lorentz' formula "yields results that are independent of direction".

Lorentz' formula may fit to the evident increase of particle mass depending on squared velocity. I wonder if there is really compelling evidence for time depending on v squared: time dilution, length contraction and all that.



While the Doppler effect plausibly depends on the sign of relative motion, the claimed by SR time dilution and length contraction of light signals in vacuum correspond to...


Addressing the Doppler point separately:

"If Einstein's 'time-dilation' and 'length-contraction' are really observed effects then I am wrong. Maybe you are confusing them with the plausible effect that is named after Christian Doppler: As well known, the frequency of a signal, which is emitted or reflected from a body in motion relative to the receiver, is either blue-shifted in case of decreasing or red-shifted in case of increasing distance."

The Doppler effect cannot be...
