Higgs Boson or "The God Particle" The last piece of the Standard Model "Discussed - Part 1 HD

In episode 03 we are discussing the possible sighting at the famous Higgs Boson that is also sometimes called the God Particle. In this part 1 we analyse the recent annoucement at CERN that, at least, a new particle consistent with the Higgs boson had been found. I want to highlight that the physicists at CERN weren't using microscopes or similar tools to view the Higgs boson directly; they were looking at the energy signatures of other particles created. CERN researchers used those signatures, along with particle physics Standard theory, to claim the discovery of the Higgs boson. In Physics we mostly rely on two approaches in describing the world we live in We either build bigger and better space telescopes here on earth or in space like Hubble so we can look at the distant galaxies and check out the stars and quasars in in various stage of their life or perhaps to look really far to study the edge of the universe that is visible to our tools here on earth. We also go on and build bigger and more energetic particle accelerators to study the sub atomic - the elementary particles and the forces that hold them together in the hope to work out what is holding the universe together. In all this we have to make some basic fundamental assumptions to allow us to build the physics we need to describe our world. Here is just couple of those basic assumptions: Firstly Our ruler that measures distance in space or the clock that measures time- does so from our reference frame here on earth - so it is the same measuring tool today here now today - as well as billions of years in the past - and therefore we assume that for example the speed of light is a constant and it is the same now as it was near the big bang some 13 billion years ago. We also apply the same measuring tools in the sub atomic world -- to explain it better, let us imagine that we are microscopic & small enough to stand on the surface of the nucleus of the atom or one of the sub atomic particles -- then the proposition is that we would be still measuring the space and time using the same ruler and clock here on earth and not the smaller microscopic one on the surface of the subatomic world. So for example IMHO time may be running a lot faster close to the nucleus of atom than here on surface of earth - but since we cannot measure or even comprehend the scale - we stick with the SI standards set here on earth The Last Week Announcement at CERN is by no means the end of this chapter - the physicist Stephen Hawking once made a $100 bet claiming that the Higgs boson was fiction. A lot of physicists still think so mainly because a lot more data is needed to back up this discovery - for example we need to prove that this Higgs boson is not spinning otherwise it is just like any other particle with mass - this is not going to be easy - Furthermore even if we do find more data to prove all this, so that all the jigsaw parts of the Standard Model Theory is elegantly put together, it still is not explain gravity. To finish this episode we will have look at a great animation that explains The Standard Model and Higgs Boson a lot better than I can ever do and in the second part of this series I will go how we got here with a finer tooth comb - Also watch animation explaining "Higgs" easy way as well as Dr P Higgs himself appearance about the discovery.

Gravitational Time Dilation
 
08:30

Gravitational Time Dilation

http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/gratim.html#c4 "In special relativity, the speed of light is constant when measured in any inertial frame. In general relativity, the appropriate generalization is that the speed of light is constant in any freely falling reference frame (in a region small enough that tidal effects can be neglected). In this passage, Einstein is not talking about a freely falling frame, but rather about a frame at rest relative to a source of gravity. In such a frame, the speed of light can differ from c, basically because of the effect of gravity (space-time curvature) on clocks and rulers." Since gravity affects clock, it also affects the calculation of the speed of light if two clocks are observing the same event, if the clocks are experiencing different amounts of gravity. At the beginning i was speaking too fast or it wasnt recording right or something but this is what i said "this video is a sequal to the video evidence earth is 6,000 years old. i figured that youtubers wouldnt know much about relativity or physics, but i thought they would atleast have the courtesy to atleast research it first before they curse me out and call me a liar on the simplest facts that all phycisists accept."

Spacetime could be simultaneously continuous and discrete, in the same way that information can be

Video abstract for the article 'Spacetime could be simultaneously continuous and discrete, in the same way that information can be 'by Achim Kempf (Achim Kempf 2010 New J. Phys. 12 115001) Read the full article in New Journal of Physics at http://iopscience.iop.org/1367-2630/12/11/115001/fulltext/. GENERAL SCIENTIFIC SUMMARY Introduction and background. To unify quantum theory and general relativity is difficult in large part because of a basic dilemma: general relativity indicates that spacetime should be a continuum, but quantum field theory indicates that spacetime should be discrete, with a spacing at the Planck length of 10−35 m or larger. Correspondingly, there are candidate quantum gravity theories in which it is assumed that spacetime is continuous, while there are competing theories in which spacetime is assumed to be discrete. In the former theories it is difficult to ensure the absence of infinities, while in the latter theories it tends to be difficult to ensure that a continuum emerges. Main results. Here, aiming to resolve this dilemma, we present results that show that spacetime could be simultaneously continuous and discrete, in the same way that information can be. The transformation rules between continuous and discrete representations of information are described in Shannon's sampling theory, which is in ubiquitous use in all signal processing. In this paper, the underlying mathematics has been generalized and applied to physical fields and spacetime itself. One of the key results is the finding that the local curvature of spacetime can be understood to be a local variation in its density of degrees of freedom, i.e., in the local information carrying capacity of spacetime. Wider implications. The new information-theoretic concept of a spacetime that is both continuous and discrete could be very helpful for describing spacetime both general relativistically and quantum theoretically.

Quantum Gravity a new theory Quantum Atom Theory

Quantum Gravity a new theory Quantum Atom Theory

This video will explain a quantum theory of gravity uniting classical and quantum mechanics and explaining Einstein curvature of spacetime. The universal gravitational force needs a universal and constant opposite force to maintain it. In Quantum Atom Theory this force is electromagnet radiation that is radiating out in quantized spherical waves fronts in a process called stimulated emission. When the wave fronts of two spheres come in contact we will have destructive and constructive interference. The the wave fronts that are out of phase will cancel each other out and the wave front in phase will superimpose. This will course an unbalanced force and the two objects will resonate together in a process known as gravity. Because atoms consists mostly of empty space EMR of short wave length like x-rays can penetrate the objects and therefore every single part of matter can take part in the gravitational interaction. The gravitational field will propagated at the same speed that EMR moves, the speed of light therefore there is no instantaneous action at a distance. We have the inverse square law because the surface area of the light sphere increases with the square of the radius. Thus the strength of the gravitational field is inversely proportional to the square of the distance from the source. In Quantum Atom Theory the light spheres of EMR that create the gravitational fields that hold the Planets in motion around the Sun are also the same light spheres that we have in quantum physics. These light spheres are a mathematical quantity known as the wavefunction and create the probability of the Uncertainty Principle. It is this wave function that continuously creates Einsteins curvature of spacetime at the quantum level of the atoms. Each atom will radiate out light sphere of quantized wave fronts. Each expanding wave front will create a probability of a future event. When a wave front comes in contact with another atom the wave-particle duality of the light will collapse. This will create a new quantum particle in space and a new moment in time that will be part of the curvature of spacetime. The wave function represents the time continuum at the most fundamental level. The probability of the Uncertainty Principle is the same probability that the observer will have with any future event.

How Gravity Works

A non-technical overview of the first EVER end-to-end proposed explanation for how gravity works - as published in a scientific peer reviewed journal paper,Nov. 2011. HOW planets and stars 'curve spacetime' (as Einstein described it), WHAT that means in practical terms, and WHY objects (and light) follow that 'curvature'.

The geometry and probability of Time within Quantum Mechanics
 
10:00

The geometry and probability of Time within Quantum Mechanics

In Quantum Atom Theory time has geometry and a symmetry that can explain the probability and non-locality of quantum physics. The forward momentum of electromagnetic radiation forms Einsteins curvature of spacetime and form part of the dynamically evolving geometry of time. Because it is impossible to achieve absolute zero all atoms radiate EMR continuously and it is this emission and absorption of EMR that creates the forward momentum of time at the most fundamental level. Because light is EMR in the visible spectrum this process is visible to us in the Two Slit Experiment and this video explains the paradoxes of this experiment. This theory fits in with Einsteins theories on relativity because the individual atoms create their own spacetime geometry relative to their position and momentum therefore there is no universal time. The geometry of time is an innate property of matter whatever form or shape it takes. Each photon electron coupling will create its own symmetry around its point in spacetime. This can be observed either has a point in space over a period of time or has an area of space at a moment in time. But not has both therefore we have Heisenbergs Uncertainty Principle and the paradoxes of quantum mechanics. In Quantum Atom Theory infinity is an actual reality of our Universe not a mathematical paradox. Infinity can always be divided into ever decreasing or increasing sets of infinities (Cantors continuum hypothesis) because each atom is creating its own spacetime geometry by the forward momentum of EMR that can always be divided into sets of infinities Read more at quantumartandpoetry.blogspot.com

A Quantum Field Theory that explains the Arrow of Time
 
04:26

A Quantum Field Theory that explains the Arrow of Time

One of the fundamental puzzles of our Universe is that we have a definite 'arrow of time' a distinction between the past and future. This puzzle can be explained in this theory because an important aspect of Heisenberg's Uncertainty Principle ∆×∆p×≥h/4π is that it does not work in the same sense forward and backward in time. It is within the rules of quantum mechanics to calculate backwards and find out what the position and momentum was at some time in the past. This precisely fits in with our everyday experience of the nature of time, moving from a known past into an uncertain future. Add to this that Heisenberg's Uncertainty Principle can be reformulated to say that it is impossible to simultaneously measure the energy of a particle and the interval of time ∆E ∆t ≥ h/2π for which it has been in existence. When we consider what happens in a region of empty space in a very tiny interval of time, there will be a large uncertainty in the energy content of that region. It has been said that energy appears out of nothing, but the most simple and most beautiful explanation for this is that we have a process of continuous creation or change. A process of change that at the smallest level can be seen as the Planck Constant ħ=h/2π as a constant of action within the uncertainty of the flow of Time itself forming the dynamic geometry of spacetime. This might sound insane, but this theory is based on just two simple postulates 1. The first is that the quantum wave particle function explained by Schrödinger's wave equation does not just predict what the wave-function will be in the future, but this process represents the forward passage of time ∆E ∆t ≥ h/2π or Arrow of Time itself photon by photon or moment by moment. 2. The second is that Heisenberg's Uncertainty Principle ∆×∆p×≥h/4π that is formed by the wave function is the same uncertainty we have with any future event This process of continuous creation or change we see and feel as the flow of time itself. Forming an infinity of possibilities at every point in space and every moment in time that we can interact with turning the possible into the actual!

two slit experiment within a new quantum theory

two slit experiment within a new quantum theory

This video explains the Two Slit Experiment by giving us a new quantum theory on the forward momentum of the Time Continuum or arrow of time. Only an understanding of the geometry of time and the broken symmetry of spacetime will explain the entanglement of quantum physics. Modern physics cannot explain the continuous forward momentum of time. In Quantum Atom Theory the individual atoms are creating their own Time by the emission and absorption of electromagnetic radiation. The observer as a group of atoms is also creating his or her own spacetime geometry. Therefore the observer is the only true reference frame and we have relativity. The observer collapses the interference pattern of the Two Slit Experiment because he creates new moments of Time in the form of a photon electron coupling. Just like in Newtons first law of motion the interference pattern will continue to maintain its state unless acted upon by an external force. I have tried to make this theory as simple as possible in the belief that everyone should be able to understand it. In this theory we can see a World in a Grain of Sand and a Heaven in a Wild Flower, Hold Infinity in the palm of your hand and Eternity in an hour, just as William Blake said. But on a more scientific level this theory can unite Quantum Mechanics and Classical Mechanics giving us one universal law of physics. Read more at, www.quantumartandpoetry.blogspot.com

The Missing Universe of Dark Matter

Almost the entire Universe is missing: 96 percent. There is not enough mass in galaxies to maintain their rotational spiral shape and stop stars spinning off into deep space. To explain why galaxies are not breaking up mankind has come up with the idea that 96 percent of the Universe is Dark Matter!

Stephen Hawking CERN Lecture: The Creation of The Universe Part 2

Professor Stephen Hawking, rightfully regarded as one of the greatest theoretical physicists of modern times, gives us an exciting lecture at the heart of theoretical physics at the experimental epicenter of this research, the Large Hadron Collider at CERN. Hawking's work in searching for the theoretical framework for producing a Unified Field Theory has lead him to some truly remarkable conclusions in his career which paralells that of CERN's search for elementary particles and the forces that govern them. His work with Roger Penrose on the singularity conditions that arise in General Relativity lead to an extention of Roger Penrose's theorem for non-rotating, uncharged black holes to a universe where the Big Bang itself did not arise from a spacetime singularity. His independant work on Virtual Particle-Antiparticle Pairs around a black hole event horizon has lead to the famous Hawking Radiation scenario, which still awaits experimental and observational experimentation. Hawking's own expertise in Black Hole Thermodynamics along with his work(an infamous bet) with the renowned Physicist Kip Thorn are classic physic's stories. Hawking's popular science books and TV shows are works of art in and of themselves. Hawking's latest work has been involved in M-Theory, particularly in the case of modelling the geodesics of spacetime with relation to Feynman's Sum over Histories Path Integral formalism in Quantum Field Theory. Hawking has concluded that spacetime, under his formalism's can arise from nothing due to the spacetime curvature with no initial conditions, creating the Universe for free. Hawking's groundbreaking work and his continueous struggle with ALS has inspired millions of scientists and laypeople across The Planet.

"Before the Big Bang?" (2005), the original lecture by Roger Penrose (part 5 of 9)

"Before the Big Bang? A new perspective on the Weyl curvature hypothesis" This is the original lecture by Roger Penrose on his fascinating new model of the universe, its origin and future, and of the "Big Bang"; held at the Isaac Newton Institute for Mathematical Sciences (November 7th 2005). Originally published at http://www.newton.ac.uk/webseminars/pg+ws/2005/gmr/gmrw04/1107/penrose/index.html See also http://www.youtube.com/watch?v=ghbDGBOYp1g and http://www.perimeterinstitute.ca/index.php?option=com_content&task=view&id=551&Itemid=568&lecture_id=7276 for other lectures by Penrose on this theory. See also http://www.youtube.com/watch?v=pEIj9zcLzp0 for an interview with Roger Penrose on his new model. See also http://accelconf.web.cern.ch/AccelConf/e06/PAPERS/THESPA01.PDF for Penrose's academic article about his theory. See also http://arxiv.org/pdf/0710.3879v2 for an article about Penrose's "Before the Big Bang" idea, verifying that some of Penrose's basic predictions are mathematically correct. NOTE TO THOSE POSTING COMMENTS ON THESE VIDEOS: Please stay focused on the topic. All irrelevant comments will be removed without warning. SUMMARY: There is now a great deal of evidence confirming the existence of a very hot and dense early stage of the universe. Much of this data comes from a detailed study of the cosmic microwave background (CMB)—radiation from the early universe that was most recently measured by NASA's WMAP satellite. But the information presents new puzzles for scientists. One of the most blatant examples is an apparent paradox related to the second law of thermodynamics. Although some have argued that the hypothesis of inflationary cosmology solves some of the puzzles, profound issues remain. In this talk, Professor Penrose will describe a very different proposal, one that suggests a succession of universes prior to our own. Sir Roger Penrose is a highly distinguished mathematician and theoretical physicist. He is currently emeritus Rouse Ball Professor of Mathematics at Oxford University. His research interests span many aspects of geometry, having made contributions to the theory of non-periodic tilings (Penrose tilings), to general relativity theory and quantum foundations. He has also had remarkable insights in the science of consciousness. His main research programme is to develop the theory of twistors, which he originated over 30 years ago as an attempt to unite Einstein's theory of general relativity with quantum mechanics. In 1994 Professor Penrose was knighted by Queen Elizabeth II for his service to science. He has received numerous prizes and awards, including the 1988 Wolf Prize, which he shared with Stephen Hawking for their understanding of the universe, the Dannie Heinemann Prize, the Royal Society Royal Medal, the Dirac Medal and the Albert Einstein prize to name a few.

Stephen Hawking Cosmology Lecture Geneva University

Professor Stephen Hawking gives a public lecture at the University of Geneva after his trip to CERN in 2009 where he saw the Large Hadron Collider. Regarded as one of the greatest theoretical physicists of modern times, Hawking's work in searching for the theoretical framework for producing a Unified Field Theory has lead him to some truly remarkable conclusions in his career which has given us new knowledge in the workings of the cosmos. Hawking's ground-breaking work has grabbed the attention of scientists and laypeople the world over with his popular science books and abstract reasoning on the nature of physics on elementary and grand scales. His work with Roger Penrose on the singularity conditions that arise in General Relativity lead to an extention of Roger Penrose's theorem for non-rotating, uncharged black holes to a universe where the Big Bang itself did not arise from a spacetime singularity. His independant work on Virtual Particle-Antiparticle Pairs around a black hole event horizon has lead to the famous Hawking Radiation scenario, which still awaits experimental and observational experimentation.
