Sure, but they are inly observed, not really explained. Pretty much like is Biology books, descriptions but no reason nor any explanation given about life and processes related to it.
Similar thing if you try and ask a random person on the street how their mobile phone really works. 99% of the people have absolutely no clue.
Btw, the so called “fundamental forces” are 7. Then on the opposite side of non-material Aether there are also 7 sub-structures or “forces”, which correspond to the 7 material (matter related).
In every atom or such particle there are ‘components’ (or features) related to all forces material and non-material: gravity, Time, taking Space are such material features.
Regarding the concept of Time travel and why it is plausible…
As the Universe expands and nothing is ever at one place in the Aether, there is a Time path\trace of all the Past (but not for the Future, will explain the Time travel in the Future*… in the future below! Pun intended!)
It means that in the Aether itself there is ‘a record’ of all past states of the matter\occurrences.
Going back (somehow!) in Time and killing your grandfather, does not mean you would automatically disappear. It is more likely going back a we pages in the book and scratch\erase a few words.
But if you decide to stay in that Past time, it is actually your current Present time an your existence won’t be disturbed.
Has anyone did it? No, because it won’t change anything that already happened in the development of the Universe in the Aether.
If then decide to go into the Future (the Time travel way) nothing will have changed. You would see the future expansion of the Universe as it already happened. I imagine it as erasing a few characters in some frames on a film and then to expect they will disappear somehow automatically for the rest of the movie, which already has been made\lived.
That of course implies that Time travelling to the Past, somehow must involve getting the Aetherial information of the past state of the expansion of the Universe. It has to be done outside of its material existence, hence the need of the Aether and the Beyond (non-material structure).
Now, here I am… from the Future (see above)
Going back in Time would mean that the future of the Universe will be developing without your presence in it (your intended deeds\life\existence).
This means that you can go back to any future moment (further from your leaving point in Time) without expecting to see yourself. It is really that simple.
You might as well have intended to go back in Time, but rather decided to stay in the non-material (let’s call it 0 Time existence) and just wait (waiting is a nonsense in this case, I know). It is rather letting the Universe develop and spinning, etc. without your material structure.
Imagine it like your material structure being “slowed down” then a few non-material seconds would result in probably hundreds if not thousands of years of ‘normal’ material development of the (future) universe. Hence you can now chose to either go in to the same point you left (your present time won’t change and you will be making your movie but with some possible notion of how it might develop without your presence in it) or just plunge in to a future point (in its Future). This is the Time travel to the future.
I strongly believe that there were and are some individuals (humans, maybe animals as well) who can do that naturally while asleep. We might call them prophets, witches, wizards, etc. but it is an ability of the Thought (without involving the material body).
With technical manipulation (material devices to conduct material manipulation) we might be able to involve any material bodies (yours) in such Time travel.
It would be similar for the Space travel. The prerequisite would be to not let the “spinning” of our material structures get out of synch with the “0 Time” in relation to the underlying structure of the Universe. I think we can do that by manipulating the “spinning” and most likely this must be done via some Thought related process… but this concept I have not understood\developed so far.
The material device we would need is just for body protection in and out of current to next environment.
I also believe that such travels in Space and Time are happening even now not necessarily on Earth nor by earth humans, but the rate of success is very low. Most experiments result to dematerialisation or just unintended crashes\deaths into stars or collisions into unknown areas of the Space.
