Time Doesn’t Reverse Like Physicists Thought Here’s Why
Time Doesn’t Reverse Like Physicists Thought Here’s Why
Using black holes as their models, an international team of researchers has found that if three or more objects move around each other, history cannot be reversed.
Historically, scientists have had to rely on statistical arguments based on increasing entropy to explain why time only moves in one direction.
Until now.
Researchers believe they have demonstrated that fundamentally time cannot be turned backwards in all cases because things don’t always happen the same way in reverse.
The researchers came to this conclusion after performing two black hole simulations where they calculated the orbits of three black holes that influence one another.
Find out more about these 3 simulated black holes, how they broke the symmetry of time, and how this discovery will shape our understanding of the basic laws of nature in this Elements.
