Time dilation demonstrated through applied physics setting with potential practical use.

I invented a tool in relativistic physics to communicate with the past. This is possible by for instance morse code of visible laser light that time travels due to a magnetic field combined with interferometry. It is a practical application of relativistic physics that allows for time travel of EM radiation. The speed of light c is constant but EM radiation can bend under an electric field and/or a magnetic field. This means that photons can be accelerated. The net velocity remains c but the direction is altered and possibly the intensity of the EM wave or the wavelenght/frequency and therefor the energy. Now picture what happens when you use a solenoidal coil of conductive wire and chase an electrical current through it? You generate a magnetic field through the open space through the coil under a 90 degree angle with the conductive wire. What happens when you send a laser beam of visible monochromatic light through the solenoid? The light "bends" along the axis of propagation of the laser beam. This means the photons are accelerated. The speed of light is however constant within the reference frame of the photons. Therefor these photons travel through time compared to an outside reference frame observing the laser beam traveling through the solenoid.

Another phenomenon where time dilation of EM radiation occurs is in interferometry. The speed of light is c but the speed of the inteference wave front is 2c. This is easy to understand. Constructive or destructive interference of visible light waves occurs when the photons of two light beams of monochromatic light form a standing wave of sorts. So these photons both travel at the speed of light. What happens if we now put in a signal in morse code, short or long, seperated always by 1 second? We get visible interference upon every signal that is either a short pulse or a long pulse obviously. But when? The first such pulse is introduced by blocking one of both light beams for a short or long length of time and the second such pulse is introduced one second later. Light travels at 300 000 km per second so if we detect the interfering wave 600 000 km away from the source, the second pulse should occur a second before the first one and we have event reversal. The speed of light is c = delta-x/delta-t = 300 000 km/s so we can now understand this is correct. Both light beams travel at the speed of light towards each other so if they both travel for one second after colliding when they start traveling in opposite directions they will have traveled a distance of 2 x delta-x from each other within this 1 second time of flight. So now we still have to worry about how to visualise light beams traveling for 600 000 km. One obvious manner would be to use mirrors, for instance four mirrors at each corner of a square. We can also integrate beam splitters in our setting so that the same light is circling a bit longer while still forming one monochromatic laser light beam or standing wave. An issue would be that 600 000 km is too long for either one or both light beams of the interferometer setting. So we can now cheat a bit by placing one or more of the previously mentioned solenoidal coils around the light beams in between the mirrors. If the light travels through time other than through space then 1 second time of flight may occur sooner than after 300 000 km so that the laser light does not disperse and weaken too much.

In fact if we use such a setting we should see several shades of light in the past previous to introducing the signal, with the weakest shade occuring the earliest in time. Now after such as setting is build we can build a second one right next to it and copy a shade from the future in the present and send it to the past in the second setting. After this we copy it in the past and send it further to the past again in the first setting and so on and so forth.

So in summary you should just build an interferometry setting. Then place a solenoid around both laserbeams and chase an electric current through it. Let the monochromatic light beams go through these coils. Try to position the solenoid in two different directions so you have the magnetic field positioned in two directions. Possibly you will be able to copy the shades already like this. If not you should further 'delay' the light beams with beam splitters and mirrors and chase it back through a lens or magnifying glas to have it travel longer so that minimal accelaration of the photons can be visualised. Obviously you place a solenoid around all straight lines of laser light.

Further I mention that it is a bit counterintuitive to assume that the interferometry wave front travels at 2c instead of c. You should draw out the velocity vectors of the photons however. Question: When does interference occur? Answer: When two photons collide. This happens after the photon from the first light beam has traveled a distance delta-x1 towards the photon of the second light beam during a period delta-t1 after being emitted from the source. Likewise the second photon has travelled a distance delta-x2 over a period delta-t2 before it collides with the first photon and interference occurs. Obviously delta-t1 = delta-t2 = delta-t as the photons collide at the same point in space-time. Also the speed of both photons is c = delta-x1/delta-t = delta-x2/delta-t. The interference front does however progress a distance delta-x1 + delta-x2 over the time delta-t = delta-t1 = delta-t2 or v-interference = (delta-x1+ delta-x2)/delta-t = 2c.

You can verify this easily if you have the interference front travel for long enough by mirroring and using beam splitters prior to chasing it through a lens. You can also 'delay' the light further with the solenoids as in this manner the photons get accelerated along their axis of propagation. As the interference front progresses at 2c while the photons travel at c this means the interference occurs at different times along the light beam. It is a fairly simple setting that I propose here and you should just toy with it until you get the desired practical outcome.

Please feel free to build such a setting and use it as you wish. Just contact me if you need any help.

It is my understanding that light bends because the light beam is slowed more in one direction than another. The term "accelerated" in this case means to be slowed rather than sped up. In physics, the term "accelerated" means a change in velocity. It could mean that an object is caused to either go faster or slower. What evidence indicates that light goes faster when passing through a solenoid?

Also, in special relativity, relativistic speeds do not directly add or subtract. All observed velocities are subject to Lorentz contraction so there is no point in space where an observer could measure the combined velocities of colliding wave fronts to be greater than c.
