So as soon as you can possibly figure out how previous forms of us merely loop our lives over and over day by day in the past without it being apparent you won't even put a slight fingerprint in the discovery of time travel.
If time is a concept created by humans, then explain the relativistic effects of slowing time as the speed of light is approached. Time is a physical entity, as tangible as matter and energy and is fundamental to the fabric of the universe. Hardly a created concept - unless you assume everything is.
Exactly. I can't physically picture what time IS, but I know it's a real, tangible thing. It's been proven.
However, time cannot go backwards. Events, places, things, and situations are not directly tied to and move with time. You cannot visit the past. I believe there are other dimensions beyond the 3 (4) we are familiar with, and those dimensions might even exist around us with things in them we just can't view, but I don't believe other copies of US are living in those dimensions in different portions of our own lives. That just doesn't make any sense at all. Unless you believe that every time a junction in life occurs, every possibility happens at once and splits into two separate instances, but that's pretty far-fetched.
You can visit the future, but only by traveling near the speed of light yourself, so that the world passes you by in minutes, and then there's no way to get back. But who would want to do that?
Teleportation may be possible via quantum entanglement of every atom of your body, but the chances that we could ever devise a way to control that precisely and to reconstruct everything at the destination without ANY noticeable effects on the body's organs and brain are very VERY unlikely.
