Below are John Titors posts on Temporal Divergence and VGL system which is the inspiration for the Temporal Divergence Meter.
See Bold text for details related to Temporal Divergence Meter.
I saw the posting requesting the basic systems for a gravity distortion system that will allow time travel. Here they are:
-
Magnetic housing units for dual microsignularities.
-
Electron injection manifold to alter mass and gravity of microsingularities.
-
Cooling and x-ray venting system
-
Gravity sensors (VGL system)
-
Main clocks (4 cesium units)
-
Main computer units (3)
I would guess the temporal divergence between this worldline and my original is about 1 or 2 percent. Of course, the longer I am here, the larger that divergence becomes from my point of view.
The computer units and gravity sensors ârecordâ your trip and you are quite easily able to return to your point of origin. I am aware that research is being done on faster units with more accurate clocks. I imagine that they will be able to go back farther with a higher degree of divergence confidence.
Whatâs the largest technical problem when traveling in time?
The hard part of traveling through time is not the bending of gravity but the plotting of your course and holding to the basic âpositionâ in your environment. This is done through a system called VGL (variable gravity lock).
Basically, the unit takes a reading of the local gravity and samples it during the âtripâ in pulses. If the gravity is too far off, the unit stops or reverses itself to the last sample period where the readings were correct. If there is some sort of failure, the unit shuts down and drops out to where ever you may be.
When traveling to other worldlines there is a system of clocks and gravity sensors in the machine that sample the environment before dropping out. Itâs called VGL, (variable gravity lock). If a cement block were there, the machine would âbacktrackâ until it sensed relative congruity to the original gravity sample. A great deal of time and effort goes into picking just the right spot since you cannot physically move during a displacement.
Time travel is achieved by altering gravity. This concept is already proven by atomic clock experiments. The closer an observer is to a gravity source (high mass), the slower time passes for them. Traveling at high speeds mimics this effect which = the twin paradox of faster than light travel. However, this type of gravity manipulation is not sufficient to alter your worldline.
The computer system is connected to the unit through an electrical bus. There are actually three computers linked together that take the same signals from the gravity sensors and clocks. They use a Borda error correcting protocol that checks the integrity of the data and trips the VGL system.
if you change cars do you have to re-adjust the time machine?
Yes. But itâs a function of the VGL system. A gravity baseline is taken and rechecked every time the unit is used. A new vehicle would alter the gravity signature.
Why did you go to 1975?
The first âlegâ of my trip was from 2036 to 1975. After two VGL checks, the divergence was estimated at about 2.5% (from my 2036). I was âsentâ to get an IBM computer system called the 5100. It was one the first portable computers made and it has the ability to read the older IBM programming languages in addition to APL and Basic. We need they system to âdebugâ various legacy computer programs in 2036. UNIX has a problem in 2038.

It is thought that being close to a gravitational field has a biological effect on all matter including cells. The effect is to slow the movement of electrons in the orbits of their nucleus, which slows the mechanical and biological functions of the observer close to the gravity. Thus the passing of time is a local phenomenon depending on how close you are to a gravitational source.
This is one example of a theory involving âtime shellsâ progressing in size and intensity around a gravitational point from all matter. The more massive the object, the larger and more influential the time shells around it (like an onion). Another offshoot of this theory is that kinetic energy is actually the conversion of stored energy in the atom as it passes through time shells in a gravitational field.
It is actually quite dangerous to get too close to a distortion unit as it enters or leaves a worldline. It vents radiation and has a very strong localized gravity field. Personally, I worry about that a great deal.
It can be adjusted to some degree (the gravitational fields). The CG (center of gravity) is adjustable within about 4 feet and the unit is effective about 10 to 12 feet in either direction from there. The vertical distance is quite a bit shorter and is determined by sensors in the unit.
Depending on whether or not you are going forward or backward, the footprint of the unit is different. I wouldnât quite say it âscoopsâ up the ground cleanly. It sort of vibrates it loose and takes it along for the ride. It looks like someone raked the ground an inch or so deep with a small hand hoe or shovel. The negative ergosphere âscoopsâ up the front and back areas of the field. The positive ergosphere leaves a longer area near the center of mass. Itâs about a cubic foot of dirt spread out over six square feet or so.
What would happen if something touched the distortion field as it is turned on?
It would be quickly spread out over the lateral length of the gravity field. Imagine being squished and stretched at the same time. I would imagine anything left after that would be vaporized and generate static electricity.
Has the time machine ever been used while it was moving?
Not that Iâm aware of. Its important that it remain as still as possible so the gravity sensors can get a good lock. The divergence confidence would be way off if the vehicle were moving.
The question involved how the time machine could travel to Earth in the future or past since the position of the planet would change in space. The question also asked about life support during travel and how physical structures are avoided.
This is actually a very good question that parts and pieces of the answer are scattered around in previous postings. I am often surprised that it is not the first one asked. You are correct; this problem is actually the most difficult part of time travel. Although some of your assumptions about matter displacement are a bit off, the problem is real. Inside the displacement unit are a series of very sensitive clocks and gravity sensors. This system is called the VGL (variable gravity lock). In simple terms, before the unit âleavesâ a worldline, it takes a base reading of the local gravity and adjusts the Tipler sinusoid to âlockâ into that position. Although the temporal physics of this statement are wrong, in effect, it holds you to the âEarthâ. During travel, it periodically checks to see that the field has not varied. If it does, it stops and reverses course or drops out at that point. Buildings and other terrain features are avoided in the same way. Yes, we do bring oxygen in the vehicle with us but we do not lose atmospheric pressure.
Important Begin
Wonât even a small divergence between worldliness cause everything to look different to you as compared to your worldline?
The divergence measurement refers to the local gravitational field as compared to the point of origin. It is merely an empirical indicator of overall change in a worldline. Some things that are quite different on one worldline have very little effect as time passes and the worldlines appear to âconvergeâ again and look very similar. Worldline changes are not exponential; they act more like chaotic attractors with varying effect depending on their size and location.
Important End
