(Business Insider) Time travel is theoretically possible, calculations show. But that doesn't mean one could change the past.

US already uses time travel (Andrew D. Basiago)

Time travel is possible based on the laws of physics, according to researchers. But time travelers wouldn't be able to alter the past in a measurable way, they say. And the future would essentially stay the same, according to the researchers.

Imagine one could hop into a time machine, press a button, and journey back to 2019, before the [plandemic] novel coronavirus made the leap from animals to humans [with the aid of "gain of function" research sponsored by the US military].

What if we could find and isolate patient zero? Theoretically, the COVID-19 pandemic wouldn't happen, right? Not quite, because then future-you wouldn't have decided to time travel in the first place.

The ancient portals already exist for ogres.

[Except that there are timelines where it did happen. One can change the future by going into the past, on another timeline.]

For decades, physicists have been studying and debating versions of this paradox: If we could travel back in time and change the past, what would happen to the future?

A 2020 study offered a potential answer: Nothing [or the Mandela Effect]. "Events readjust around anything that could cause a paradox, so the paradox does not happen,"

Germain Tobar, the study's author previously told IFLScience. Tobar's work, published in the peer-reviewed journal Classical and Quantum Gravity in September 2020, suggests that according to the rules of theoretical physics, anything we tried to change in the past would be corrected by subsequent events.

Put simply: It is theoretically possible to go back in time, but we couldn't change history [except that we have, according to such whistleblowers as attorney Andrew D. Basiago, so it is possible]. More
