M-THEORY

It’s been 50 years since string theory was first proposed, but now some new research could call it all into question. WTF is Quantum Retrocausality? (ft.

It predicts not one but some 10500 versions of spacetime, each with their own laws of physics. But with so many universes on the table, how can the theory explain why ours has the features it does?” On the Cosmological Implications of the String Swampland https://arxiv.org/abs/1806.09718 “We study constraints imposed by two proposed string Swampland criteria on cosmology.

FIRST BROADCAST: Wednesday, 8 September 2010. BBC Newsnight. Stephen Hawking talks to Susan Watts about M-Theory, and musician Mark Everett ('E' from Eels) describes the work of his physicist father, Hugh Everett III, on the 'Multiverse'.

Subscribe to Cosmic TV for more great space, alien and UFO content: http://bit.ly/CosmicTVSubscribe Physicists found that the apparently distinct theories were identified by mathematical transformations called S-duality and T-duality. Witten's conjecture was based in part on the existence of these dualities and in part on the relationship of the string theories to a gravitational theory called eleven-dimensional supergravity.

Modern attempts to formulate M-theory are typically based on matrix theory or the AdS/CFT correspondence. According to Witten, the M in M-theory can stand for "magic", "mystery", or "matrix" according to taste, and the true meaning of the title should be decided when a more fundamental formulation of the theory is known. Investigations of the mathematical structure of M-theory have spawned a number of important theoretical results in physics and mathematics. More speculatively, M-theory may provide a framework for developing a unified theory of all of the fundamental forces of nature. Attempts to connect M-theory to experiment typically focus on compactifying its extra dimensions to construct approximate models of our four-dimensional world.

With reports of the discovery of gravity waves, the existence of the graviton is implied. This in turn has implications for string theory, M theory and indeed any quantum theory of the universe, in providing them with an empirical basis.

Rust Cohle describes the Membrane Theory. In theoretical physics, M-theory is an extension of string theory in which 11 dimensions of spacetime are identified as 7 higher-dimensions plus the 4 common dimensions.

In less than 100 seconds, Leron Borsten explains how M-theory could be the one theory to rule them all. Visit physicsworld.com for more videos, webinars and podcasts. http://physicsworld.com/cws/channel/multimedia

String Theory is believed to be the theory of everything because it unifies all particle forces of interaction (Electromagnetism;Weak Nuclear; Strong Nuclear; and Gravity). The mystery of the quantum gravity and why it is so weak is defined with the force called Graviton. In addition, it's calculations illustrate a world of multi-dimensions which is based on the vibration of the string and it's corresponding forces.

Thus far, we can break everything in the universe down to a few very small elementary particles. But they fit into strange patterns that are not understood. Some scientists believe that this is because we can go deeper - perhaps to simple vibrating strings! At TEDYouth 2012, Clifford Johnson describes these ideas, along with the concept of string theory. Talk by Clifford Johnson.

Sub atomic strings vibrate in the same way as violin strings, instead of producing notes they produce particles, each particle giving shape to the Universe.

Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.

Question: Why are there only 11 dimensions in the universe rather than something higher? (Submitted by John Menon) Michio Kaku: I work in something called String Theory, that's what I do for a living. In fact, that's my day job. I'm the co-founder of String Field Theory, one of the main branches of String Theory. The latest version of String Theory is called M-Theory, "M" for membrane. So we now realize that strings can coexist with membranes. So the subatomic particles we see in nature, the quartz, the electrons are nothing but musical notes on a tiny vibrating string. What is physics? Physics is nothing but the laws of harmony that you can write on vibrating strings. What is chemistry? Chemistry is nothing but the melodies you can play on interacting vibrating strings. What is the universe? The universe is a symphony of vibrating strings. And then what is the mind of God that Albert Einstein eloquently wrote about for the last 30 years of his life? We now, for the first time in history have a candidate for the mind of God. It is, cosmic music resonating through 11 dimensional hyperspace. So first of all, we are nothing but melodies. We are nothing but cosmic music played out on vibrating strings and membranes. Obeying the laws of physics, which is nothing but the laws of harmony of vibrating strings. But why 11? It turns out that if you write a theory in 15, 17, 18 dimensions, the theory is unstable. It has what are called, anomalies. It has singularities. It turns out that mathematics alone prefers the universe being 11 dimensions. Now some people have toyed with 12 dimensions. At Harvard University, for example, some of the physicists there have shown that a 12-dimensional theory actually looks very similar to an 11-dimensional theory except it has two times, double times rather than one single time parameter. Now, what would it be like to live in a universe with double time? Well, I remember a movie with David Niven. David Niven played a pilot, who was shot down over the Pacific, but the angels made a mistake, he was not supposed to die that day. And so the angels brought him back to life and said, "Oh, sorry about that. We killed you off by accident; you were not supposed to die today." So in a great scene, David Niven then walks through a city where time has stopped. Everyone looks like this. And there's David Niven just wandering around looking at all these people. That's a world with double time. David Niven has one clock, but everyone else has a separate clock and these two clocks are perpendicular to each other. So if there's a double time universe, you could walk right into a room, see people frozen in time, while you beat to a different clock. That's a double time universe. Now this is called F-Theory, "F" for father, the father of strings. It's not known whether F-Theory will survive or not; however, M-Theory in 11 dimension is the mother of all strings. And that theory works perfectly fine. So to answer your question, in other dimensions, dimensions beyond 11, we have problems with stability, these theories are unstable, they decay back down to 11 dimensions, they have what are called anomalies, singularities, which kill an ordinary theory. So the mathematics itself forces you to 11 dimensions. Also because this is a Theory of Everything, there's more room in higher dimensions to put all the forces together. When you put gravity, electromagnetism and the nuclear force together, four dimensions is not big enough to accommodate all these forces. When you expand to 11 dimensions, bingo, everything forms perfectly well.

Stephen Hawking poses some of the key questions that all of us sometimes wonder. He has set out to answer these questions in his new book, The Grand Design. Hawking presents M Theory as the grand solution. It's a family of different theories working similarly to a grouping of maps. He also discusses the role of cosmology, the inflation of the universe and the Planck satellite.

Prof Alister McGrath and famed physicist, and atheist, Prof Roger Penrose discuss the following questions: Is Hawking's M-theory good science?

March 14, 2018 update Professor Stephen Hawking has died at the age of 76. The world-famous scientist died peacefully at his home in Cambridge in the early hours of Wednesday morning, a spokesman for his family said. Professor Hawking's children, Lucy, Robert and Tim said in a statement: "We are deeply saddened that our beloved father passed away today. "He was a great scientist and an extraordinary man whose work and legacy will live on for many years. http://www.facebook.com/NSOTD God did not create the universe, the man who is arguably Britain's most famous living scientist says in a forthcoming book. In the new work, The Grand Design, Professor Stephen Hawking argues that the Big Bang, rather than occurring following the intervention of a divine being, was inevitable due to the law of gravity. In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is "not necessary". The Grand Design, an extract of which appears in the Times today, sets out to contest Sir Isaac Newton's belief that the universe must have been designed by God as it could not have been created out of chaos. "Because there is a law such as gravity, the universe can and will create itself from nothing," he writes. "Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. "It is not necessary to invoke God to light the blue touch paper and set the universe going." In the forthcoming book, published on 9 September, Hawking says that M-theory, a form of string theory, will achieve this goal: "M-theory is the unified theory Einstein was hoping to find," he theorises. "The fact that we human beings -- who are ourselves mere collections of fundamental particles of nature -- have been able to come this close to an understanding of the laws governing us and our universe is a great triumph." Hawking says the first blow to Newton's belief that the universe could not have arisen from chaos was the observation in 1992 of a planet orbiting a star other than our Sun. "That makes the coincidences of our planetary conditions -- the single sun, the lucky combination of Earth-sun distance and solar mass -- far less remarkable, and far less compelling as evidence that the Earth was carefully designed just to please us human beings," he writes. Hawking had previously appeared to accept the role of God in the creation of the universe. Writing in his bestseller A Brief History Of Time in 1988, he said: "If we discover a complete theory, it would be the ultimate triumph of human reason -- for then we should know the mind of God." Hawking resigned as Lucasian Professor of Mathematics at Cambridge University last year after 30 years in the position.

SETI Talks Archive: http://seti.org/talks Extra dimensions of space may be present in our universe. Their discovery would dramatically change our view of the cosmos and would prompt many questions. How do they hide? What is their shape? How many are there? How big are they? Do particles and forces feel their presence? This lecture will explain the concept of dimensions and show that current theoretical models predict the existence of extra spatial dimensions which could be in the discovery reach of present and near-term experiments. The manner by which these additional dimensions reveal their existence will be described.
