Sabine | Time Can Run in Two Directions, New Research Finds

Why time passes is one of the biggest mysteries in physics, as the fundamental laws of nature don’t reflect a difference between moving forward and backward in time.

In a new paper, researchers have shown that time might actually be able to run in two directions, meaning we might have a twin universe where time runs opposite our universe’s.


Let’s take a look.
