The Picture on the left is taken from Daniel's journal (page F). It has some interesting features, but the most interesting feature is the remarkable similarity it bears to the diagram found on the The Quantonics Website. (see below)
First of all, what should be noted is the 2003 date on the Quantonics diagram. In other words, this diagram appears to pre-date the diagram in Daniel's Journal (i.e. in terms of airdate), and therefore whoever produced the prop either used the same source as the Quantonics material did, or has direct access to the Quantonics website.
Secondly, what should be noted, is that much of the terminology and labelling is the same in both diagrams.
Thirdly, please note that anyone who attempts to make sense of the Quantonics website does so at their own risk.
OK, as this is quite complex, let's start with the easy stuff.
In Dan's Journal, the horizontal axis is position in space, and the the vertical axis represents time. The circle is called a 'space-time invariant'. We are all familiar with the notion of invariants: If you take a metre ruler, it's length is invariant even if you take it on a bus, twizzle it or throw it out the window (unless it breaks). When you travel near to the speed of light, length is not invariant, and the ruler shortens, depending on how fast you go. In the ultimate, when you reach the speed of light, the length is zero. At the same time, time stretches, and one second, travelling at the speed of light would last an eternity.
In relativity, there is an invariant quantity, and it's a combination of all three dimensions of space, and one of time. However, to make this work, we need to use "complex" numbers, that is a combination of real numbers representing space, and imaginary numbers representing time. (note that 'imaginary' here does not mean fanciful or fictional, but rather that the formulas use the square root of minus one, which, for a long time, people would not accept as "real"). The arc of the circle in Dan's Journal represents all the places and times that you could "theoretically" end up if you used up the same amount of spacetime. Some use more time than space, some use more space than time. You can use all the spacetime by sitting still, and just travel through time (into your own future), or you can use it all by zooming from one location to another at the speed of light.
The scales on the two axes have been arranged so that the 45 degree slope of the triangle represents objects moving at the speed of light. Angles greater than 45 degrees (measured from the base upwards) use up more time than space, and are called "timelike"; angles less than 45 degrees use up more space than time, and are called "spacelike". If you look carefully at Dan's Journal you will see these are labelled as such. Please note that In order to travel in a spacelike manner, you would need to exceed the speed of light.
In relativity the speed of light is finite, however the thory of relativity and the theory of quantum mechanics have some discrepancies in this matter. Recent experiments in Superluminal Tunneling and Quantum entanglement, have demonstrated that information could be transmitted at faster than light speeds.
Now, looking at Dan's diagram again you will see two vertical dots on the right hand side of the diagram. These dots correspond to the vertical line and two dots labelled "sitting still" on the right. This represents an object occupying the same location at two different times. This is the normal passage through spacetime, of "sitting still", i.e you stay in the same place, but you end up in different times because time flows.(There are actually issues with this, as you can never in fact 'sit still';the Earth is moving, the Galaxy is rotating etc etc.) With these two dots, both are in Real Space, but "Imaginary" Time, and this is the normal state of affairs.
However, there are two horizontal dots in Dan's diagram further up the triangle. These dots correspond to the horizontal line & two dots on it on the diagram right. This movement seems not to be possible, because it represents a case where an object exists at the same time in two different locations. However, in this case, if you think of 'space' as flowing rather than time, then the object is held at the same time, but has "flowed" into a different space.
An interpretation of this is that the diagram says that in holding the position of an object in the same space, this forces it to slide through the imaginary dimension (i.e. time), in order to avoid a paradox. This is what we interpret as the 'flow' of time.
However, the diagram is symmetrical and if you can succeed in 'holding' an object in the same position in time (e.g. by superluminal tunnelling), then time becomes the real part of the invariant quantity, and as a result, space becomes the imaginary dimension, and we then slide into different 'imaginary' spaces in order to avoid a paradox. This gives a clear explanation of why "Flash-Sideways" timelines exists, and Faraday already knew about this prior to his death.
If this theory is correct, then the FST will have been caused by an event where one object was attempting to occupy the same time & space as another object, and the universe slid sideways to avoid the paradox.
Any offers for what the event was?
