Since this thread seems to follow the usual chain of thought on
What happens if we could go faster than light, or do we time travel?
I have decided to look from a slightly different perspective due
to my original perspective being:
It's not impossible just improbible. If time travel was possible then
problems could occur from people cloning with the use of time (jumping back five minutes, waiting with yourself to jump again in five minutes time, so although a person is lost from the future on X number worlds, one world is invaded by X number of people)
First of all, if you travelled faster than the speed of light, you have to decide what speed to define lightspeed. The problem is though if you define a wavelength and speed, the wavelength can be distorted by gravity, so the wave changes it's position within the spectrum.
Namely if a number of waves are at first compressed together (
A), throughout their period of travelling they can stretch out(
B), which means the same number of waves exists but their dimensions like length, height and width will differ.
This I believe is especially noticable within astronomy, as distant stars will be seen as particular parts of the spectrum, as the rest of the light either hasn't reached here yet or our distance is so far that only a particular visual spectrum occurs.
This causes a problem if you speculate that you could re-enter at any given time point, in truth you would be spread throughout more than one point of time because all the light frequencies that had been heading towards you is a matrix of differing time segments, even if only milliseconds, but it's still enough to make it difficult.
This also brings up a question of "
Heisenberg's Principle of Uncertainty"
"The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa. "
Of course the relevance of this principle that Heisenberg made and pointed out to Schrodinger was in understanding Matrix Mechanics (Quantum Mechanics), the understanding was I believe more meaningful for the time in that respect due to the measuring equipment.
(Namely using photons to look at an atom through a lenses, like they did back then. The photons would bombard the atom and cause it instabilites within it's matrix, the abnormalities couldn't be calculated because of the uncertainty of their occurances and where future postions would be. The only cure for the ability to measure without the Uncertainty principle dictating that a measurement would be void, was/is by using wavelengths that are so small that they don't cause "as much" of an impact on the matrixing of the atom.)
Of course Heisenberg's principle is now extend to two points that you have to think of in relevance of Time travel.
When you enter your time jump all your atoms have to be synchronised with that jump, otherwise they will lose alignment (And you'll be strewn across time in molecules as your electrons are slingshotted at higher speed than the majority of you, or slung behind you to accumilate less speed, or you could end up nothing but a pile of ash on the floor.)
(The above shows an Object where all matrices at that point intersect, and how they react as they head towards the observer)
The other is re-entry, as I mentioned all light matrices would be mis-aligned, of course they would realign at a set distance point (And particular points along route). Of course some will probably exclaim it wouldn't matter for the amount of waves, but this is a bit like a cross-section of then entire matrix stream of spectral frequencies.
Another person that placed some information to the relevance of this would be Schrodinger, through the use of his hypothetical experiment "Schrodingers Cat".
(Cat stolen from cover of John Gribbon's book "In search of Schrodinger's Cat", Original Illustrator David Scott)
The experiment consisted of A box large enough to hold a cat, a Geiger counter's probe was placed into the box (Inaccuracy within my diagram I placed the whole geiger counter in the box), a radioactive atom, placed within range of the geiger probe.
The geiger is connected to a hammer with a piece of string, which is suspended above a glass vial containing a poisonous toxin.
Schrodinger Hypothesised placing a cat (his guinea pig) into the box and closing the lid, while eveyone outside pondered at what was going on inside.
The idea was simple, while the cat was within the box it existed between two states, Alive and Dead. The reason was that the radioactive atom would eventually degrade to a point where the geiger counters needle would stop over the central position, at this point the cat would die from the poisonous toxin escaping from the broken vial, as the hammer falls and brakes it.
Of course while the radioactive atom was not fully degraded (but in the process of degrading) the cat would exist in a multiversal state of the geiger needle moving from one side to the other and back again, crossing the centre (flatline).
My "well" drawn stickmen is a representation of what could occur to schrodingers experiment. I've made the left a negative Blue stickman and the right a positive red stickman, Both of are positioned differently. The central stickman is a mixture of both left and right, while also containing it's own position, but acts like a Multiversal state. Where a singularity occurs, you see just the colour of the left or the right position (Or the centrals normal postion in black).
The purple colour is a Multiverse position where the stickmen's positions all align.
in another version of Schrodingers cat called (Wigners Experiment) there is a point where the person(substitute for cat) could die, not from gas, but by a Wavefunction collapse. It actually is a bit like passing out, the wavefunction collapse occurs when a parallel is created successfully and a particular energy (for instance a brain signal) decides which parallel to exist within and moves to a parallel while another parallel will lose its energy.
(this kind of makes me imagine how a blob of water can react in space. Of course thats becaus I saw some footage of a blob of water in space)
Of course there is an alternative where the signal exists in both, but this occurance is due to the creation of the parallel being done on perhaps another experimentee. This too can be harmful as it could reate Duel heart signals or stronger ones etc.
This occurs at the 0 of the stickman diagram, because the stickmen don't line up, and because all the parallels are different, the multiversal state suffers from a Quanta increase.
