The loud title of the article, of course, does not mean that it will directly give ways to do this. Sorry if you gave false hopes. This article is one of the first steps towards understanding the essence of time and options for managing it (of course, this does not mean time management) with a focus on practical implementation. Many people would like to return to the past for a while and correct their mistakes or even save a loved one from death. Unfortunately, science does not yet offer us ready-made options for this, and all theories for moving into the past are based on fantastic unrealistic wormholes, black holes and superluminal motion, on which you cannot build a real "time machine", more mundane options are needed.
Here are my reflections on this topic and attempts to understand where to go next, so that a rollback in time and changing your past in reality will someday become possible, as now it is easily possible that something 50-100 years ago seemed fantastic. The article was written for those who want to better understand the essence of time, as well as to motivate enthusiasts to engage in practical research and experiments in creating units for moving into the past / changing it, as well as organizational work to attract scientists, laboratories, and finance to solve this problem ...
I believe that in the future (even in the foreseeable) there will be some kind of chronotechnology that will enable us in life, like in a computer, to press the "cancel" button.
Moving to the future is already a reality: at near-light speeds or high gravity, time slows down (for example, in comparison with Earth). For the tester, this takes 1 second, and for the rest of the world, say, a year (depending on the value of speed or gravity). The tester got into the future a year (one second less) ahead. There is also a biological way: suspended animation (for living organisms).
With the past, everything is more complicated, since not only the physics of moving to the past has not been developed, but even the logic is ambiguous. Logic options when traveling to the past.

Friends, write your thoughts on this topic in the comments, arrange a brainstorm, submit fresh ideas on how to practically translate back in time into reality and correct your mistakes there (preferably at the modern level of technology development). Don't get hung up on Albert's TO, she works to move into the future; perhaps a different principle will apply to the past.
