Time Machines

Physicists realize time-varying strong coupling in a magnonic system

With all the progress with magnets I've been waiting to see something like this. This machine manipulates time in a causal manner that doesn't violate Relativity, but it can use time echoes and other things as if multiplexing time. Current theory says its only distantly related to Noether's Theorem and the symmetry of life, the universe, and everything, but their math is self-contradictory. Theoretically, you treat time as a spectrum if you want and, using synchronized networks, you can process time both forwards and backwards simultaneously, which would violate causality, by stopping time entirely inside the machine. Which of course, would violate the HUP.
