The parallel worlds constantly influence one another, researchers claim
This is because, instead of a collapse in which quantum particles 'choose' to occupy one state or another, they in fact occupy both, simultaneously
The theory could resolve some of the irregularities in quantum mechanics
It states some worlds are almost identical to ours, but most are different
Theory may even create possibility of one day testing for these worlds
Imagine a world where dinosaurs hadn't become extinct, Germany had won World War II and you were born in an entirely different country.
These worlds could exist today in parallel universes, which constantly interact with each other, according to a group of US and Australian researchers.
It may sound like science fiction, but the new theory could resolve some of the irregularities in quantum mechanics that have baffled scientists for centuries.
The team proposes that parallel universes really exist, and that they interact. That is, rather than evolving independently, nearby worlds influence one another by a subtle force of repulsion. They show that such an interaction could explain everything that is bizarre about quantum mechanic
The team from Griffiths University and the University of California suggest that rather than evolving independently, nearby worlds influence one another by a subtle force of repulsion.
They claim that such an interaction could explain everything that is bizarre about how particles operate on a microscopic scale.
Quantum mechanics is notoriously difficult to fathom, exhibiting weird phenomena which seem to violate the laws of cause and effect.
'The idea of parallel universes in quantum mechanics has been around since 1957,' said Howard Wiseman, a professor in Physics at Griffith University.
'In the well-known 'Many-Worlds Interpretation'', each universe branches into a bunch of new universes every time a quantum measurement is made.
'All possibilities are therefore realised – in some universes the dinosaur-killing asteroid missed Earth. In others, Australia was colonised by the Portuguese.'
'But critics question the reality of these other universes, since they do not influence our universe at all.
'On this score, our 'Many Interacting Worlds' approach is completely different, as its name implies.'
Instead of a collapse in which quantum particles 'choose' to occupy one state or another, they in fact occupy both, simultaneously.
The holographic model suggests gravity in the universe comes from thin, vibrating strings. These strings are holograms of events that take place in a simpler, flatter cosmos
The universe is a hologram and everything you can see - including this article and the device you are reading it on - is a mere projection.
This is according to a controversial model proposed in 1997 by theoretical physicist Juan Maldacena.
Until now the bizarre theory had never been tested, but recent mathematical models suggest that the mind-boggling principle could be true.
According to the theory, gravity in the universe comes from thin, vibrating strings.
These strings are holograms of events that take place in a simpler, flatter cosmos. Professor Maldacena's model suggests that the universe exists in nine dimensions of space, and one of time.
In December, Japanese researchers attempted to tackle this problem by providing mathematical evidence that the holographic principle might be correct.
The holographic principle suggests that, like the security chip on a credit card for example, there is a two-dimensional surface that contains all the information needed to describe a three-dimensional object - which in this case is our universe.
In essence, the principle claims that data containing a description of a volume of space - such as a human or a comet - could be hidden in a region of this flattened, 'real' version of the universe.
In a black hole, for instance, all the objects that ever fall into it would be entirely contained in surface fluctuations. This means that the objects would be stored almost as 'memory' or fragment of data rather than a physical object in existence.
Like Everett, Professor Wiseman and his colleagues propose the universe we experience is just one of a gigantic number of worlds.
They believe some are almost identical to ours, while most are very different.
All of these worlds are equally real, existing continuously through time, and possessing precisely defined properties.
They suggest that quantum phenomena arise from a universal force of repulsion between 'nearby' worlds which tend to make them more dissimilar.
Dr Michael Hall from Griffith's Centre for Quantum Dynamics added that the 'Many-Interacting Worlds' theory may even create the extraordinary possibility of testing for the existence of other worlds.
'The beauty of our approach is that if there is just one world, our theory reduces to Newtonian mechanics, while if there is a gigantic number of worlds it reproduces quantum mechanics,' he says.

'In between it predicts something new that is neither Newton's theory nor quantum theory.
'We also believe that, in providing a new mental picture of quantum effects, it will be useful in planning experiments to test and exploit quantum phenomena.'
'For us at least there is nothing inherently implausible in the idea,' added Professor Wiseman.
'For fans of science fiction it makes those plots involving communication between parallel worlds not quite so far-fetched after all.'
The ability to approximate quantum evolution using a finite number of worlds could have significant ramifications in molecular dynamics, which is important for understanding chemical reactions and the action of drugs.
Professor Bill Poirier, Distinguished Professor of Chemistry at Texas Tech University, has observed: 'These are great ideas, not only conceptually, but also with regard to the new numerical breakthroughs they are almost certain to engender.'
And heres a very interesting tale of a woman who entered a parallel world,that is very compelling,
Parallel universes, dimensions that nearly resemble our own, were once pondered by Plato, and proposed mathematically by Princeton University graduate student Hugh Everett III in 1954. These parallel worlds, common in myth, have been staples in science fiction since Edwin A. Abbott’s 1884 novel, “Flatland: A Romance of Many Dimensions.” More modern science fiction, like the dimension-jumping television program “Sliders,” and Philip K. Dick’s novel “The Man in the High Castle” (in which the Axis won WWII), gives us exciting glances at worlds like, yet unlike, our own. Exciting unless you stumble upon one of these alternative dimensions yourself as Carol Chase McElheney did in early March 2006.
Rain pounded McElheney’s car as she drove through San Bernardino, California, to spend a few days at a sheepdog trial in Perris, California. As she topped a hill south of the city, she saw a road sign for nearby Riverside. Her family roots were put down in Riverside in the early 1800s and she wanted to visit familiar places, such as her old house, and the cemetery where her grandparents are buried. “I’ve been going to Riverside since I was a baby,” McElheney said. “I’m real familiar with the city. I know my way around. I knew where my grandmother lived. I’ve been to the cemetery. I knew where I was going.”
As McElheney thought of visiting her grandparents’ graves, a chill ran through her. “Just as I decided to visit the cemetery, a huge blast of cigar scent entered my car,” she said. “It was pouring rain out, and I had my windows rolled up. My grandpa smoked cigars, and he died when I was five and that’s all I remember about him.”
Just as quickly as the smell floated through the car, it was gone. She drove past Riverside and on to Perris where she checked into a hotel and attended the dog show.
The next day McElheney attended the first sheep dog trial, then drove to Riverside. She didn’t like what she saw. “I could not find anything familiar,” McElheney said. “I used to live there after college.” Her street wasn’t the same, it was just wrong. The bungalows with small yards looked the same age as her old house, and the numbers were right, but her house wasn’t there. “I could not find my old place,” she said. “I thought they couldn’t have torn the house down and built another house in that 1920s style to fit into the architecture. None of the houses looked familiar. They all looked different.”
Then she drove to the street where her grandmother once lived, stopped the car, and looked around in amazement. “It was totally different,” she said. “None of the houses were anything like I remembered. No tall trees, her house wasn’t there. The numbers were in the same range, but the houses were all new. Grandma’s house and my aunt and uncle’s house next door were gone.” All the homes on what should have been her grandmother’s street were modern ranch-style houses lined by bushes, nothing like her Grandmother’s big, Tudor home with towering eucalyptus trees in the yard. “It was just gone.”
So was the cemetery. “The cemetery where my grandparents were buried was just not there,” McElheney said. “I drove around the block where it was supposed to be, and it was just fenced off with weeds inside. No gate, driveway or anything.”
Confused, McElheney pulled away from the empty lot to see if she could find anything familiar. She did. She recognized Riverside City College and Central Middle School. “Some of the other stuff was right. The college looked right, the middle school looked right,” she said. But when she pulled onto University Avenue, things were markedly different. “University Avenue was a main drag and there were scary looking people, so I got out of there,” she said. “I looked for the Mission Inn and it wasn’t there.”
University Avenue, once home to restaurants, insurance companies, banks and motels, was now, “completely ghetto,” McElheney said. “It was all graffitied-up and deserted.” To the point she was afraid to stop and ask directions. It was on University Avenue she realized something otherworldly was happening to her. “The thing that occurred to me is if I got out of my car something weird would happen,” McElheney said. “I thought if I talked to someone I’d be forever caught in this weird version of the ‘other’ Riverside, or that they weren’t going to be human. The more places I tried to recognize, nothing matched up. Nothing looked familiar.”
After a couple of agonizingly frustrating hours, McElheney turned the car around and went back to Perris. “Everything was normal,” she said. “I was afraid I’d go back and the hotel wouldn’t be there or my key wouldn’t fit. Everything was as it should be.”
A few years later McElheney’s father died and was to be buried in the same cemetery as her grandparents, the cemetery she saw as an empty fenced-off, weedy lot. “It was back to what I remembered,” she said. “He was buried next to my grandparents. The rest of the city looked like it did when I lived there after college in the ’70s. My cousin was there and she said her house and my grandma’s house are still there. University Avenue was normal looking and the Mission Inn was there. We had lunch there. I felt comfortable. I didn’t go back to the other areas to check them, but I knew they would be okay.”
What happened to Carol Chase McElheney? She’s convinced she slid into another dimension – one that was less than friendly. “I just got the feeling if I got out of the car and talked to someone I was going to fall off the edge of the earth. I’d end up being missing,” she said. “It must have been a dimensional thing. It looked like it was 2006, but I’d taken a different path. It looked like Riverside had just taken a different direction.”
May I introduce you to my beloved friend Jenny Funkmeyer and her parallel university
I had a weird &slightly scary incident of seeing into a time slip or parallel world portal many years ago in my late teens while living in a flat, I had a friend over staying and we were in the lounge and I walked across the room towards him and stopped in the middle as I saw what I could only explain was some kind of light entering the room but there was no windows or lights on so where did this light source come from I didnt know..Anyway I knelt down and looked at this light and my friend said what are you looking at & came over to see it also,as I reached out to touch it my hand went straight threw it and became invisible,my friend freaked out like a drama queen, he said don't you go any further your gonna vanish into ghod knows where, anyway I was staring into this light or rip as I called it cos that's what it looked like a tear in some fabric, and I could see what I thought were peoples legs,with shoes on them,walking on a pavement and I could hear sounds,like people talking as that you'd hear in a cafe you know its people but you cant say exactly what they are saying to repeat it back..it was real freaky and that's when I knew 100% there was a parallel world running in conjunction to ours..and somehow this tear had happened in the matrix and we could see through into it..it closed in about 20mins and we couldn't see it again. Gees if I had of gone through it I may not be here now to speak of it lol..
Wow. Omg. That makes it seem so much more real you know, when you’ve personally consciously experienced it. That is amazing. Also interesting it was just once for a moment like a rip or tear rather than say a memory….
It was like a portal opening but in a tear/rip shape made up of just light,so not a round circle portal.. how or why it did it in my lounge in the flat at that time, I really don't know also why I didn't disappear into it when my hand did I also don't know,and its never happened again.
