I write on another site google my name Eugene Bunt. I'm merely explaining my interpretation of what Einstein wrote 100 years ago. It is all backasswards but it adds together nicely. check out Einstein's book 'The evolution of Physics' at about page 120, "rising elevators".

@euG5555 No thanks, I've been doing work with relativity since 1973. My favorite part it the Lorentz transformation for time dilation. Where Ship_Time = Earth_Time / Sqare_root(1 -(VxV/CxC)) where C is the speed of light. I'm American so I use miles which equals 186,282.396 miles per second give or take 7 ten thousandth of a mile.

Actually at this point relativity has become pretty elementary, so my attention is much more into quantum mechanics now. The issue is there's not a single human that understands it and never has been. Quantum electrodynamics (QED), a relativistic quantum field theory of electrodynamics, is among the most stringently tested theories in physics. It works wonderfully but we have little more than a superficial understanding of why it works.
Sorry I don't have a great way to show math on this platform.

The Lorentz transformation (as seen from a horizontal movement) shrinks the photon width but lengthens its wavelength which also means it slows its time rhythm. Time is the measure of how far light can travel in one second. Time slows in the presence of mass, and space elongates as in embedding diagrams. Light is absorbed and radiated by electrons, the electron jumps from one shell to the next without occupying any location between energy levels (Max Plank and the ultraviolet catastrophe) so the photon is probably a square wave. Elements radiating light can be identified by their spectrum, each element has its own unique electron arrangement, if there is not an electron available to radiate a certain color there will be a black line in its spectrum specific to that element. These spectral identification lines will redshift when the light is coming from a massive star, which means light can travel farther when coming from the greater gravity of a massive star. You can think of it as a Doppler shift of light coming from an object moving directly away from you. The fabric of space elongates. Light moves farther between crests, when it meets an electron, the electron will jump farther. Time is measured by how far light can travel in one second, which is now a greater length.

Gravity, which is warped space-time per Einstein has a lot in common with electrons and photons. The distance of the electron energy-shell level from the nucleus of an atom out to the fourth level in multiples of 5.29*10^-11 times 2, 8, 18, 32. The number of electrons at these shell levels corresponds to 2n^2 where n is the shell number starting from closest to the nucleus, or, 2, 8, 18, 32. I would guess a mass-less photon to be a square-wave movement of space segments, because of the way electrons move from one position to the next without occupying any space between positions ( Max Plank “the ultra-violet catastrophe). A photon has two dimensions, length, and height devoid of a time element.

On page 202, in the book, The Evolution of Physics, by Albert Einstein and Leopold Infeld, there is a table of the distance of a falling object from a tower with a height of 256ft; the stone reaches the ground in four seconds.

Time in seconds→ Elevation in feet

0→ 256

1→ 240

2→ 192

3→ 112

4→ 0

Divide the elevation by 8; the results are 32, 30, 24, 14, and 0. The differences between the numbers are 2, 6, 10, and 14. Add the differences together and you have 2, 8, 18, and 32. The similarity in number progression suggests that there is a correspondence between electron energy-shell levels and acceleration over time in a gravitational field.

@euG5555 LOL Not about photons, photons are a special case. This is normal matter. A spacecraft travelling at relativistic speeds shortens in the direction traveled or length, increases in mass and slows down time. It does nothing to width.
In fact time dilation is what curves space toward mass, space always bends toward the place where time passes slowest. If however you were to attempt to reach light speed you'd never get there because you're attempting to accelerate with ever greater mass. At high enough speed the spacecraft would just collapse in on itself to form a quantum black hole.

@Willow_Wisp What do you do in your spare time, sit in a library and read? Not serious really.

@dalefvictor As a kid I wanted to be a Vulcan a large proportion of the time, I was alone anyway most of the time and yes, I lived in the High School Library. My first date was a Wiccan I met in that library.
Is it any wonder I absolutely loved Buffy the vampire slayer?
Teck wasn't part of my childhood, so I had to build my own.
I built a 250 thousand volt Van de Graaff generator and used it to provide the static charge to drive a particle accelerator I made of Pyrex tubes, a refrigerator compressor I used to generate a vacuum, and a 0.003 mm tungsten filament I sealed at one end of a large 3 inch in diameter tube that was 3 feet tall with bees wax.
At the upper end I sealed it with a disk of aluminum with holes drilled in it and covered with aluminum foil and again sealed with bees wax. Every 3 inches along the tube I wrapped bare copper wires that acted as a wave guide and on top I had a tray that served as the target which held up the stainless steal sphere I build out a couple of large metal kitchen bowls about a foot and a half wide, just like the generator.
So the two were set in such a way that the bowls of the accelerator and generator touched. Once I took 120 Volt power through a bridge rectifier and capacitor bank it could be applied directly to the tungsten filament after the generator was up and running and you then had a radiation supply.
I also built an ion engine, and in the attic of our barn I painted the ceiling and walls with portraits of attractive people I saw in magazines.
I joined the Navy at 17 and scored a perfect score on the Navy's test for the Nuclear power program.

I don't know why I wasn't noticed and groomed for better things.
I could have been a lot more, not that my career isn't an endless list of technical accomplishments, but I wanted research and acknowledgement, so I do my own research and accept that I'll never be acknowledged, I mean who does that? Get acknowledged for more often than not being the smartest person in the room? It doesn't happen.
It makes me wonder what would have happened if I had been financed for the education to be a PhD level physicist. It was all I ever wanted to be, until space had positions for someone like me.

Incidentally being homeless and sleeping in your car during a pandemic gives you insight into living in a vehicle with cramped quarters that you can't just abandon. I never want to be a damned astronaut, but I didn't know that then.

So yea Dale F Victor I am a highly qualified and certifiable weirdo, and like Gonzo I'm good with it.

@Willow_Wisp Did you know a man names Vern Stairs, from the nuclear program? He was a friend in high school wh went into this program.

@dalefvictor No I served on the USS Samuel Gompers, a repair tender out of 32nd street San Diego. The name doesn't ring a bell. I got out in 1982.

@Willow_Wisp He would have been way before you. Just thought I would ask.
