Note this divestiture has to do with a surplus in physics and the disclosure, takes no responsibility for malapropiations of this technology.
In order to time travel, one must make a super-relavistic event.
This event is some device, which supersedes the standard background frequency, in which time and space are realized by the observer.
This might go under the temage, of a super relativity tensor, event.
This is where a tension, may be made, for an n amount of time variable, so that utility access can be attained, in order to access other times?
Velocity in time travel in an applicable way to also travel in time.
However if one establishes a super-tensor event, within any geometrical shape, then it may be possible for this super-scalier event, to be modulated either forwards, or backwards in time.
Any sub-realm, within the confines of the traveling tensor, many be considered a super relativity event, as this event inside of the said tensor, also travels.
In nature, super relativity events happen naturally.
So if there is man, possibly existing outside of supposed original man on Earth, then they too, might have access to super-relavistic travel events.
The disclosure of this information, does not take any responsibility for misuse of supposed time travel, for either mal ends, selfish ends, or other uses, which may cause branched time or dead end time phenominons, within proposed parallel time lines.
It is thought that Earthbased man is raise in somewhat cattle fashion, so these devices may or may not pose a threat to any mal-application, or otherwise of time travel principles.
Sincerely, truly
