Can time run backwards as well as forwards ? Image Credit: NASA/ESA/ESO
Scientists have put forward a new model in support of the idea that time can run in both directions.
The idea that there could exist an almost limitless number of parallel universes is nothing new, but what if some of those alternative universes were actually running in reverse ?
The concept of a backwards running universe has been around for some time, but now researchers from California and Massachusetts have come up with a new theory indicating that this bizarre phenomenon could arise based on much simpler principles that had been previously suggested.
Key to this idea is the assertion that the direction in which time flows doesn't actually matter because it would still ultimately behave in accordance with the known laws of physics. We take our concept of time - one that flows forwards - for granted, but that doesn't mean it can't go backwards too.
What this means is that there could exist a parallel universe where all the events that happened in the past from our perspective will actually be set to occur in the future.
How this would work from a practical point of view however remains unclear - would dead people spring back to life, become progressively younger, turn in to babies and then be "unborn" ?
While we are unlikely to ever experience such a universe ourselves, the possibilities of what it might be like certainly represent an interesting and mind-boggling thought exercise.
Fans of the BBC sci-fi sitcom Red Dwarf will probably recognize the below clip set during an episode which explored what it would be like to visit such a universe - with hilarious consequences.
In other words: Harte I appreciate what you said, Harte - and treating it as an intellectual exercise I agree - but for the universe to be truly isolated even a "window" looking from one to another is impossible. Even that "window" means you aren't "looking" at another universe.
Actually, this could be very handy. Like most people, there are a lot of mistakes made over the years in our lives, like being inconsiderate to others and maybe even abusive. You then re-consider the errors of your ways and would like to go back in time and correct them and make it right. And also, of course, it would be good for the little things in life like when you get home and you realize you've forgotten that jug of milk from Wal-Mart....Ah Dang it, re-wind!
I always take everything scientists say with a pinch of salt. half the stuff they say has no proof As opposed to...... who? It depends on the science- some of it is hypothetical, some of it is observational. But given the human race's firm grasp on both of those disciplines and ability to come up with educated guesses, it's a bit foolhardy to take everything scientists say with a pinch of salt. After all, there are plenty different kinds of scientists. Engineering is a science, would you argue with a structural engineer who deems something unsafe? Mycology is a science; would you disregard a m... [More]

It's okay. It all evens out because scientists take everything ali smack says with an entire salt mine. As for a backwards-running parallel dimension...... a great concept that Bob Grant and Doug Naylor really took the reigns of, but for me it just doesn't logically work. But then living in this real... [More]
If you were somehow transplanted into the other dimension, you wouldn't be able to tell the difference as far as the flow of time. Harte I don't believe that. I saw a documentary where they actually got scientists through a dimensional gateway into said backwards-running reality, and they were able to function in a way normal to our dimension, including talking, drinking water AND eating an egg forwards. it was most interesting.
"Time" can be bizarre. We know from experiments that time itself can be "warped" This appears to be more of an exception than a rule. From what we know "time" is alterable under special circumstances. But in the "slowing down" as opposed to "reversal"
Time itself is merely counting. Take away our clocks and calendars then explain what time is. How we measure time is based on patterns in our solar system much like how we measure space is based on fractions and percentages of our world's size. Time therefore is a method to observe and measure the seasons, our planet's position at a given time and the 'distance' of events relative to eachother. Given the lack of terminology on what time really is, it is difficult to explain how time isn't a definite unit of a measurable 'thing' except within the framework of mathematics and counting. Now, I kn... [More]
