Is physics the key to time travel?

All science is based on observations, or at least it is supposed to be. No such thing has ever been observed, so it is strictly science fiction. The only thing we know for sure about time is that there is some such thing, although in most cases it is wise to consider it imaginary.

Physics could possibly be part of it. It would be so weird to be able to do that! I'd be afraid to time travel, I think...

However, I don't know how possible this is in the first place. I don't know if people will ever be intelligent enough to go back in time or move forward in time, I've got to be honest here.

Physics is the key to everything.

It would require a new type of physics....

Imagine that the "vacuum" of space contains an ocean of energy. When objects or energies travel through space, they encounter resistance. One way to envision this is by using a Michael Phelps as an analogy. Phelps swims as fast as he can through the ocean, but he has to endure resistance from the ocean waves and the water itself. His limit is light speed, which is the limit for energy in normal space. Now imagine that Phelps is a Surfer, rather than a Swimmer. He goes along with the flow of the waves, riding upon them. He no longer encounters resistance from the ocean, it propels him along just nicely, without friction. Now as long as he has a power source on his surfboard, (like an engine), and it does not interfere with the ocean waves, he can exceed light speed. Going with the grain, rather than against it, he can surpass the fastest speed known.

Even light encounters buffeting resistance from the "quantum foam" of space. When consciousness guides energy flow, it can circumvent resistance by becoming one with this energy and one with the fabric of space-time. Consciousness is equipped with the apparatus necessary to merge with the fabric; it can mirror its surroundings, anticipate alterations in flow, and change direction in order to go with the flow.

Once one merges with the flow of the fabric of space-time, one can exceed the light speed barrier. When energy smoothly melds with space-time, relaxing into it, energy and information can travel instantly from place to place. Quantum entanglement is the result of energy melding with space-time. Psychic powers, in the form of precognition, are the result of energy melding with the fabric of space-time. People who are young have a greater connection in general to the fabric of space-time, thus they naturally more psychic and apt to experience synchronicities (coincidences). As one ages, examples of coincidences for the majority of people become less frequent. This explains "old skeptics".

Once one exceeds light speed, going superluminal, time travel is feasible. A machine would simply have to completely meld with the fabric of space-time, immersing itself in it. Inner and outer environment would have to be in agreement, a time machine would merge with it's environment. Such a machine would fundamentally "go with the flow".

Connect intimately with the fabric of space-time, and you will enable time travel. Getting energy to align with the fabric of space-time is the key.
