We are comprised of energy just as everything in the universe. Since everything is energy I would think that “yes” one could project themselves to a different point on the time line.
In math the number line goes from zero to infinity just as the time line. It also goes in the negative just as time.
Is it possible? In my opinion ANYTHING is possible.
Just like jesus, god, Santa and the Easter Bunny, magic isn’t real. It is scientifically plausible to go forward in time, but not backwards (at least, not without figuring out how to harness Tachyons; little sub-atomic particles that appear to flow backwards, against time). But to go forward in time, you need to be traveling at the speed of light or faster.
Let’s say you’re orbiting around the earth at the speed of light for what to you is 5 years. When you come back to earth, 5 years passed for you, but for everyone else, it’s been much longer. This is because physical time (aging) is actually fictional, it is nothing but our perception of what the earth’s gravitational force gradually does to our bodies over the years of gravitational pressure pushing/pulling our bodies downward.
No science, whether magical or material, can physically take you back in time at this point in human progress, although I’m not certain it can at all. I don’t think time works that way.
You could probably psychically “relive” that time, but unless there’s some specific lesson you feel you need to learn by reliving it, that’s probably ill advisable. There are certain methods used in non-hypnotic past life recall which could be useful. Lucid dreaming might also offer some assistance.
