Hmmmm....

‘Time Crystals’ Could Upend Physicists’ Theory of Time
In February 2012, the Nobel Prize-winning physicist Frank Wilczek decided to go public with a strange and, he worried, somewhat embarrassing idea. Impossible as it seemed, Wilczek had developed an apparent proof of “time crystals” — physical structures that move in a repeating pattern, like minute hands rounding clocks, without expending energy or ever winding down. Unlike clocks or any other known objects, time crystals derive their movement not from stored energy but from a break in the symmetry of time, enabling a special form of perpetual motion.

Another theory may be standing on its head

Faster than light particles found, claim scientists: Particle physicists detect neutrinos travelling faster than light, a feat forbidden by Einstein's theory of special relativity
It is a concept that forms a cornerstone of our understanding of the universe and the concept of time – nothing can travel faster than the speed of light.

But now it seems that researchers working in one of the world's largest physics laboratories, under a mountain in central Italy, have recorded particles travelling at a speed that is supposedly forbidden by Einstein's theory of special relativity.

Scientists at the Gran Sasso facility will unveil evidence on Friday that raises the troubling possibility of a way to send information back in time, blurring the line between past and present and wreaking havoc with the fundamental principle of cause and effect.

Particle traveling faster than light? Two ways it could rewrite physics.
European scientists are shocked by an experiment that showed particles moving faster than light. The result, if confirmed, could challenge Einstein's signature theory on relativity or point to a universe of more than four dimensions.
