Physicists Say Time Travel Simulation Is Possible: Here's How

Most people see time as a one-directional arrow in the universe's symphony. But the world of theoretical quantum physicists is one in which the direction of time is far more flexible. These experts can calculate, simulate, and observe retrograde time, providing an intriguing insight into reverse time travel.

A group of scientists has shown that these simulations of reverse time travel contain the key to solving physics puzzles that have, up until now, eluded conventional understanding. David Arvidsson-Shukur, a physicist at Cambridge University, was the experiment's leader.
