Time Travel via Electromagnetic Radiation

First off, let me say that I don't know everything. I don't have all the technical details. I have no documents to show you at the moment. I'm just a poor ranch hand from a small hillbilly town in Northern California. I shoveled gravel and dug ditches for a living. I ain't know no specifi-cay-shuns.

It's kind of like when you own a car, but aren't a mechanic. You know it has an engine. You know it runs on gas. You know how to drive it. But you don't know all the parts it has. You don't know all the tolerances, or that you can't just tighten a bolt down when you're working on it, you have to torque it to spec.

You could waterboard me 'til the cows come home trying to figure this out, and it wouldn't change anything. It would be like asking a fish to climb a tree. It's not happening.

Supposedly the way you achieve time travel through the electromagnetic spectrum is by getting a frequency high enough, well beyond microwaves, which can be in the hundreds of gigahertz or more. You can get a wavelength small enough to fit through all the molecules and atoms that make up our universe.

The lower the frequency, the longer the wavelength. For example, the wavelength for Extremely Low Frequency is several miles in size. The higher the frequency, the smaller the wavelength. Extremely High Frequency can be as small as 1mm.

It's supposedly possible to get the wavelength so small that it can pass through the physical world into other dimensions, where time exists. The shortest wavelength currently known is gamma radiation, which can have wavelengths of less than 10 picometers.

The smallest atom in the universe is the hydrogen atom. It's estimated to be about 53 picometers in diameter. However, the distance BETWEEN atoms can be 60 to 520 picometers. A wavelength under 10 picometers should be more than adequate to pass between them.

If you could modulate a signal that was based on gamma rays, you could be able to send information THROUGH our physical world to the other side. If gamma rays can indeed pierce through our dimension, then they should be able to find their way back OUT on the other side. This is why you would need to aim your transmitter at the location in outer space where Earth WAS in the past.

From what I understand, however, is that the higher the frequency is, the less suited it is for long-distance communication. Which means it adheres to line-of-sight propagation. But that might not even matter if your signal's wavelength is so small that it passes between atoms. This is not a conventional radio broadcast.

They would be beaming this out into space. It would cost a profanely enormous amount of energy to do this. It probably has a dedicated nuclear power plant solely for it. Maybe even two or more. Likely hidden underground. Or maybe somewhere way out in Antarctica.

Two or more power plants could be wired in series, then paired to an obscenely colossal capacitor array in order to build up enough voltage and amps to blast this signal out into space.

And how are they generating the gamma rays themselves? This is not something you can buy in a store. Gamma rays are typically produced in nuclear reactors and physics experiments. Likely bleeding-edge stuff only found in laboratories.

There is, however, a device called a "Gamma Knife". It's a type of radiosurgery device used to treat brain tumors. It uses Cobalt-60, which produces gamma rays. It could theoretically be scaled up into a transmitter to beam out a modulated frequency to a waiting gamma spectroscopy detector on the other side.

Now, I don't know if this applies to gamma rays, but typically, high frequencies also have a phenomenal bandwidth capacity. ELF can barely transmit text, but WiFi, which is in the gigahertz, can stream movies and other high-definition video. Something in a frequency far higher than the latest 5G should have a gargantuan bandwidth.

It would probably make sense to prepare a "package" of data and send it like a burst transmission. With that kind of bandwidth, you could probably transmit the entire Internet at once without much trouble.

This brings to mind something I remember reading about a long time ago. Something that's known as Gamma-ray Bursts (GRBs). These are supposedly the most powerful releases of electromagnetic energy known to man, second only to the Big Bang.

It was also found that these GRBs weren't releasing electromagnetic frequency omnidirectionally, but through two narrow beams. Meaning you could aim it. These are said to be from distant galaxies. Could this be galaxy-to-galaxy communication?

The amount of power being released seems right if you need to communicate through mind-boggling distances and ensure it makes it past incomprehensible quantities of the most abundant elements in the universe. The universe may be so huge that the only way to communicate between galaxies may be through time travel equipment. The inhabitants might never meet, but at least they can say 'hi'.

There is also a theory that parallel universes exist side-by-side. And that our galaxy itself IS the universe. It's already too huge to explore. NASA's best estimate is the Milky Way is composed of about 100 billion stars. Even if we achieved light-speed travel, it would take 200,000 years just to cross it. And that's not stopping to see sights and studying anything we find scientifically.

To add other galaxies on top of that is patent insanity. It's estimated that there are hundreds of billions to 2 trillion galaxies out there. Each could have the same amount of stars or more. That's not infinite, but it might as well be due to how unobtainable and unrealistic it would be to explore all of that.

The other galaxies we can see out in space are actually alternate universes of our own existing in bubbles side-by-side to us, and that is reflected in how different they look. They are also possibly at different ages, which would change what color light the stars give off.

And supposedly, there are one or more galaxies out there reminiscent of our own Milky Way. According to this theory, travel between alternate dimensions would simply be traveling to the end of our galaxy or "universe" and then continuing on until we reach the other.

So anyway, that's the best I can do on this subject. I only have a theoretical degree in physics, after all.
