Is it possible to use giant magnets to flip the magnetic field into a negative side and create time travel?
I bet all the geniuses who work on that sort of thing have already thought of that. If time travel were that easy we'd already be doing it. Theoretical Science has lots if theories that are impossible or unlikely practically.
sure but who has a magnet that big.
I don't think so... Giant Magnets?
No, I don't think so. How could they demonstration that? It is not possible so far because they never made it done.
What does the magnetic field have to do with the flow of time? We put people in giant magnets all the time (PET scans) and they don't go back or forward in time.
