I don't so much believe in wormholes. What I do believe in is Time Potential, like a voltage. Just like at any time, or point in space any object traveling faster than light will travel back in time, Einstein's Theory of Relativity and Special Relativity, really only point to the fact that the potential is there. Gravity Warps time, a photon in transit experiences no time, a muon can experience only a few fractions of a second traveling near light speed.
Things that warp time, like gravity, any concentration of energy, magnetic fields, all exist to show that there are alternate means of dilating time.
So, when it comes to matter, the potential is more like static electricity or a shockwave. The closer you get to hypersonic in air, the closer you are to having the projectile in a vacuum. The closer you get to light speed, the closer you get to where the permittivity and permeability of space produce a shockwave that places 1/2 projectile in a compression front, and the other half in negative time. The space time foam doesn't work with all matter in the same direction.
CP Violation of the Big BangSo, the first parallel Universe, you would or could drop into, time progresses backwards in. The Future of that Universe is the past of ours. Our Universe's end, is the beginning of that Universe. It consists of anti-matter in bulk from the initial Big Bang. That is in so much as to say, that time is completely separated from Space as a dimension that co-exists with space, just like permittivity and permeability are two separate measurable entities. An imaginary perfect space, excludes all three, time, permittivity and permeability.
Now, I believe you can stretch the permittivity and permeability of space and potentially access negative time, or anti-time. That would be done with a 3 phase RF system. In short, you would build a plasma container and spin a magnetic field using a true 3 phase sine wave source. The interference doesn't ever stop the position of the magnetic lines from being connected to the opposing pole. So, an empty jar would be used to circulate a plasma and utilize centripetal force to produce a perfect vacuum, then a hyper vacuum caused by stretching the permittivity and permeability of space to saturation. Then the magnetic lines will snap in center, and reverse polarity. When that happens, and continues, negative time is accessable as a power loss to the system. Energy travelling in the opposite direction in time, only represents a loss. We have nothing to detect a radio wave pegged on a dimensional line of time that is inverted. All of our equipment only works as time progresses forward. So, all we could or would detect is a loss of energy and a reversal of the magnetic field lines. Just imagine electrons moving through a coil, if you reverse time for just that coil and observe it as time progresses forward the direction the electrons are moving is now reversed. That would in respect reverse the polarity of that magnetic field that came from outside of the hypervacuum. The truth is, a rotating magnetic field has the same mass as a photon, which is zero. So, it can rotate faster than light. When you look at Tesla's Columbus Egg, that form of coil winding, toroid, that utilizes destructive interference to force magnetic lines to be ejected from the core, looks to be more ideal than separate solenoid or rectangular windings, like you'd normally find on the stator of a squirrel cage motor. You would want to use superposition to center your rotating magnetic field in the plasma. Then use a frequency sweep to speed up the ions and electrons to a velocity that keeps them away from the very center. At a point where a rotating magnetic field inside the plasma is travelling faster than light, negative time should be measurable as a reversed field between the pole pieces of the rotating magnetic field. That's where you would place a coupling loop antenna to extract RF, that is riding negative time. Then the energy loss of the system should jump up, and the radiated energy/escaping radio waves should drop in intensity based upon the volume of that envelope.
The skin voltage from that isn't dangerous. But, until you experience it, I won't tell you what happens. If you'd like a training film, watch "Groundhog Day" starring Bill Murray. All you have to do to get out of that kind of situation, is not touch that wire.
