Time may run backwards in a mirror universe



Hey there, cyberpuppy! How's she going, eh? Great to think that you do take time to spiral on down to keep track of what is really happening in the universe. This universe, I mean. Speaking of which, I'm going to tease your mind a little so you'd better load up on coffee and a virtual treat or two, okay?
Scientists have proposed that there is a universe parallel to our own in which time runs in reverse. Say what?

There is still much to understand about the concept of time, the every present chronological continuum which drives ourselves and the rest of the universe eternally forward.

Now however scientists conducting a new experiment designed to better understand how the cosmos came in to being have proposed that when our own universe was created, so too was a corresponding mirror universe in which time runs backwards. (I may need something stronger than coffee...like a double espresso!)

The idea was born from the concept that all the fundamental laws of physics work just as well if time is in reverse as they do forward and that this is exactly what is happening in this mirror universe.

While it would effectively be the same universe as our own, events there would likely happen differently and would not simply be the mirror image of what is happening here.

An observer in one universe however would see events in the other going backwards.

"Time is a mystery," said Dr Julian Barbour. "Basically, all the known laws of physics look exactly the same whichever way time runs, and in the world in which we live everything goes in one direction."

Whether we would ever be able to visit this mirror universe however remains to be seen.

Aha! A most thought-provoking idea! Hmmm... the possibilities. What if...as events in our universe happen, they automatically move into that other universe somehow? Don't ask me how. I'm an amateur astrophysicist not an astro-engineer but I’d be interested in knowing what you think about these concepts!

See ya, eh!
