The orbital photon modulator was fully charged. The world of today is going to ****, so it was time to head on into the past. The device itself isn't really that high tech. The means for building it have been around once Tesla got some ideas worked out in the 1920's. The core of the device is an orbital photon modulator. It's basically a laser that doesn't let the light get out. In this case there are X-ray diode sets where one would put the flash tubes. Inside the flash chamber is a CO2 tube, and at each end is a lithium vapor chamber. Around the whole unit there are high energy reflectors. Lithium is vaporized and essentially stripped of electrons. The X-ray lasers then hammer the lithium protons while they are also contained by strong electromagnets. This collapses the protons into a micro-singularity. Essentially a teeny-weenie black hole. Since this black hole only can exist under a certain energy state and only weighs about a gram, it is easily contained in each end of the modulator. There is then this effect caused by the orbital or spin of the photons involved. This creates a tenuous quantum superstring between each singularity at the end of the modulator. By kicking it with an electro magnetic field it begins to vibrate. Think of it as a sort of quantum rubber band. At the same time it twists, gaining photon angular momentum. It's hard to explain really... Maybe the CERN Gustavsson's equations (finally worked out at about 2026 C.E.) could explain the quantum topology better, but that's asking a bit much of the layman. Anyhow, time travel involves snapping this superstring like a slingshot and enjoying the ride. The experience is odd. It's like pointing where you want to go... And then falling to your destination. Synchronization is the hard part. If you're off, you could be in deep space or another solid object. You'd better get it right or you're dead. So one falls through a tunnel, it's dark. Maybe some specks of light. Then the destination point shows as a light at the end of the tunnel. It's incredibly fast. Then when the falling sensation is the strongest (like peaking at the top of a parabola) the end of the tunnel flashes around you. You're there. Another time. Of course this is just fiction (as far as I know), but ain't it great?
