It’s possible that there is a “mirror universe” where time moves backwards, say scientists

It’s possible that there is a “mirror universe” where time moves backwards, say scientists:

This may blow your mind a bit.. It defies our physics and certainly defies all of our understanding.

From the article by Olivia Goldhill:

Barbour compares the Janus point to the moment where a river splits in two and flows in opposite directions. “It’s the simplest thing,” he says. “You start at that central Janus point where the motion is chaotic –that’s like the Greek notion of primordial chaos—but then in both directions you get this structure forming. If the theory is right, then there’s another universe on the other side of the big bang in which the direction of experience of time is opposite to ours.”

But though time could flow in different directions, that doesn’t mean we could ever experience the reverse.

“We’re on one side of the Janus point,” Mercati tells Quartz. “On one side you get your arrow of time and can never experience the other one. It’s in your past.”

I suppose in a universe with endless possibilities and even multiple universes, anything is possible. Even a place where the reverse is happening and time runs backwards.
