Dr Who Meets Professor Heisenberg

Example of a CTC.

A space-time structure exhibiting closed time-like curves. Here a wormhole connects two points at the same location in space (horizontal) but at different times (vertical). A quantum particle travelling on such a path might interact with its older self.

By Martin Ringbauer

Researchers have simulated in the laboratory how quantum particles could overcome the “grandfather paradox” of time travel.

By Martin Ringbauer

A team of physicists has challenged the limits of Heisenberg’s famous uncertainty principle by measuring quantum particles with unprecedented accuracy.
