It seems that M Theory is the system of laws that governs everything – the Grand Design. Stephen Hawking’s Grand Design: The Key to the Cosmos, Discovery 2012
Out of string theory comes M Theory. Through the Wormhole with Morgan Freeman s1e4: What Happened Before the Beginning? Science 2010
Two branes come together, inject one another with energy, then dark energy takes a trillion years or so to spread that energy out, the branes flatten then come together again. This cycle happens endlessly. ibid.
In our picture, there was a universe before the Big Bang, very much like our universe today: a low density of matter and some stuff called dark energy. If you postulate a universe like this, but the dark energy within is actually unstable, then the decay of this dark energy drives the two branes together. These two branes clash and then, having filled with radiation, separate and expand to form galaxies and stars.
Then the dark energy takes over again. It’s the energy of attraction between the two branes: it pulls them back together. You have bang followed by bang followed by bang. You have no beginning of time. It’s always been there. Neil Turok
The physicists found a second version of it. And then a third. Soon they had found five different string theories. That wasn’t single and it didn’t sound very definitive. String theory had begun to unravel. It seemed as if the dream of a theory of everything was as far away as ever. But just as the scientists were about to give up hope, a new and startling discovery would be made. This would inspire them to begin their quest again and force them at last to confront their least popular idea: parallel universes. Horizon: Parallel Universes, BBC 2002
Super-Gravity: String Theory had displaced it. ibid.
Super-Gravity though had been convinced there were exactly eleven dimensions. ibid.
String Theory was in trouble. Its five different versions meant it couldn’t be the all-embracing theory Physics was looking for. Everything it seemed had been tried to save String Theory. Well, almost everything. In a final desperate move, the String Theorists tried adding one last thing to their cherished idea: they added the very thing they had spent a decade rubbishing – the 11th dimension. ibid.
The tiny invisible strings of String Theory were supposed to be the fundamental building blocks of all the matter in the universe. But now with the addition of the eleventh dimension they changed: they stretched and they combined. The astonishing conclusion was that all the matter in the universe was connected to one vast structure: a membrane. In effect our entire universe is a membrane. ibid.
When M Theory emerged, [Lisa] Randall and her colleagues wondered if it might provide the explanation – could gravity be leaking from our universe into the empty space of the eleventh dimension? Randall tried to calculate how gravity could leak from our membrane universe into empty space. But she couldn’t make it work. Then she heard the theory that there might be another membrane in the eleventh dimension. Now she had a really strange thought: what if gravity wasn’t leaking from our universe but to it? What if it came from that other universe? ibid.
M Theory is a promising unified theory. Professor Paykl Steinhardt
We are experiencing an existential shock. Our world view has been shattered with the realisation that, yes, there could be parallel universes ... Satellite data indicates there could be parallel universes ... New theories called String Theories are giving us worlds of higher dimensions; quantum physics at the microscopic scale is also revealing to us there could be parallel universes ... The implications are staggering. Professor Maicho Kaku
At every point of any one of these people walking by, you pick a point, at that point there would be an incredibly tiny curled-up either six or seven dimensions that you just don’t perceive. Professor Bert Ovrut, University of Pennsylvania
M Theory would go even further demanding yet another spatial dimension bringing the grand total to eleven dimensions. Brian Greene, The Elegant Universe III, PBS 2003
It’s the strangest idea in the whole of science. It emerged by accident from bizarre experiments. Scientists resisted it. But a maverick would force them to take it seriously. The idea means we live in a giant bubble. Parallel Universes, National Geographic 2011
Some of the world’s most respected scientists claim these other worlds may actually exist. ibid.
Some exist far beyond the further edge of our visible universe, others hang out in a mysterious landscape full of dark energy called the Multiverse, and others are right here in the same space we are all living, but we can’t see them obviously. ibid.
You might not want to meet your other self. ibid.
[Hugh] Everett wrote what’s become the definitive argument for parallel universes called Many Worlds. ibid.
An infinite number of other realities. ibid.
There may be other worlds out there. Where there could be an exact copy of our solar system, our Earth and each one of us. The Universe s3e2: Parallel Universes, History 2008
The universe sits in a sea of parallel universes. ibid.
Remarkably, there may be four types of parallel universe out there: one could exist in exactly the same space that we are in, but it is so far away we cannot see it or reach it. In another scenario, multiple giant universes could exist in giant cosmic soap bubbles adrift in a cosmic sea of giant bubbles. In yet another scenario, many parallel universes occupy the same space and times as our universe, but because they are in different dimensions, they are invisible. In yet another, all the laws of physics are different so everything looks completely different. ibid.
The Wmap seems to show that the universe is flat. ibid.
‘We are children of the bubble.’ ibid. Tegmark
When in the 1980s scientists came up with a lyrical-sounding idea – String Theory – it promised to solve all the mysteries of the universe, including whether or not parallel universes are real. The idea is that all particles are not solid points or dots, as science said they were. Instead, if you could see up close, particles are in fact tiny string-like objects that individually vibrate in various ways ... String Theory has now evolved into M or membrane theory. ibid.
The crowning achievement of M Theory came when scientists realised that to make sense of everything, you need to think of the universe as existing in eleven dimensions. M Theory explains how the tiniest as well as the biggest things in the cosmos work. It also proposes that we all live on a giant and energetic membrane. Our universe is tethered to this wall by extra dimensions ... These membranes are also very close to each other. ibid.
