Quantum Computing. Quantum Biology. Quantum Biology. Physicists May Have Evidence Universe Is A Computer Simulation. Physicists say they may have evidence that the universe is a computer simulation. How? They made a computer simulation of the universe. And it looks sort of like us. A long-proposed thought experiment, put forward by both philosophers and popular culture, points out that any civilisation of sufficient size and intelligence would eventually create a simulation universe if such a thing were possible.
And since there would therefore be many more simulations (within simulations, within simulations) than real universes, it is therefore more likely than not that our world is artificial. Now a team of researchers at the University of Bonn in Germany led by Silas Beane say they have evidence this may be true. In a paper named ‘Constraints on the Universe as a Numerical Simulation’, they point out that current simulations of the universe - which do exist, but which are extremely weak and small - naturally put limits on physical laws. But the basic impression is an intriguing one. Weird Quantum Tunneling Enables 'Impossible' Space Chemistry. A weird quirk of quantum mechanics is allowing a chemical reaction thought to be impossible to occur in cold gas in outer space.
In the harsh environment of space, where the temperature is about minus 350 degrees Fahrenheit (minus 210 degrees Celsius), scientists had thought a certain reaction involving alcohol molecules couldn't take place, because at such low temperatures, there shouldn't be enough energy to rearrange chemical bonds. But surprisingly, research has shown that the reaction occurs at a rate 50 times greater in space than at room temperature. Now, by simulating the conditions of space in a laboratory, scientists have found a possible explanation for how the reaction occurs: quantum tunneling. Tunneling depends on the odd rules of quantum mechanics, which state that particles don't usually have decided states, positions and speeds, but exist in hazes of probability.

Physicists have long thought that the singularities associated with gravity (like the inside of a black hole) should vanish in a quantum theory of gravity. It now appears that this may indeed be the case. Researchers in Uruguay and Louisiana have just published a description of a quantum black hole using loop quantum gravity in which the predictions of physics-ending singularities vanish, and are replaced by bridges to another universe. View all Singularities, such as the infinitely strong crushing forces at the center of a black hole, in a physical theory are bad.
What they tell you is that your description of the universe fails miserably to explain what happens as you approach the singularity. Satellite orbiting Earth is guided by the spacetime curvature generated by the Earth's mass (Photo: NASA) General relativity has been summed up by the late John Wheeler's phrase: "Spacetime tells matter how to move, matter tells spacetime how to curve. " Let's follow this analogy a bit further. Simulations back up theory that Universe is a hologram. Artist's impression by Markus Gann/Shutterstock At a black hole, Albert Einstein's theory of gravity apparently clashes with quantum physics, but that conflict could be solved if the Universe were a holographic projection.
A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection. In 1997, theoretical physicist Juan Maldacena proposed1 that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter cosmos where there is no gravity. “It seems to be a correct computation,” says Maldacena, who is now at the Institute for Advanced Study in Princeton, New Jersey and who did not contribute to the team's work. Is The Universe A Hologram? Physicists Say It's Possible.
Quantum Biology. The Spooky World Of Quantum Biology. Michael Garfield The new science of quantum biology is teaching us about how the actual behavior of evolution is governed by disconcertingly spooky processes – time travel being one of them. Will quantum computation finally be realized by biomimicry, in organic systems? Evolution is the new (old) computation...and we're about to take the reins. One hundred and fifty years ago, paleontologist Thomas Henry Huxley (an autodidact and philosopher who coined the term “agnostic” and was known as “Darwin’s Bulldog” for his passionate defense of natural selection) asserted that humankind would eventually take the processes of evolution into our own hands. Within a few decades of his proclamation, a cadre of equally brilliant scientists including Werner Heisenberg, David Bohm, and Max Planck began to unravel the mysterious properties of quantum mechanics.
These two theories –- evolutionary and quantum dynamics -- can each be considered among the most important discoveries of all time. QUANTUM JUMPING. Quantum Jumping. Quantum Mechanics Reveals How We Are All Truly Connected - Learning Mind. “I am saddened by how people treat one another and how we are so shut off from one another and how we judge one another, when the truth is, we are all one connected thing.
We are all from the same exact molecules.” ~ Ellen DeGeneres We all know, deep down, that we are all connected. But is this notion of being connected only a magical feeling or is it concrete fact? The Perception of Separation As a species that grew and evolved to become one of the Earth’s most dominating forces, we came to believe that we were its greatest glory. The tricky part in all of this knowledge and wisdom that quantum mechanics has imparted to us, is that we don’t know where to draw the line. The Basics of Quantum Theory In order to truly understand what is happening at a sub-atomic level when we think of someone or when we feel the lightness of love for another; we must first bridge the gap between the micro-world and the macro-world. Quantum Entanglement’s Spooky Actions So What Does This Mean For Humans? Quantum tunnelling.
Quantum tunnelling or tunneling (see spelling differences) is the quantum mechanical phenomenon where a subatomic particle passes through a potential barrier. Quantum tunneling is not predicted by the laws of classical mechanics where surmounting a potential barrier requires enough potential energy. Quantum tunnelling plays an essential role in several physical phenomena, such as the nuclear fusion that occurs in main sequence stars like the Sun. It has important applications in the tunnel diode, quantum computing, and in the scanning tunnelling microscope. The effect was predicted in the early 20th century, and its acceptance as a general physical phenomenon came mid-century. Fundamental quantum mechanical concepts are central to this phenomenon, which makes quantum tunnelling one of the novel implications of quantum mechanics. History After attending a seminar by Gamow, Max Born recognised the generality of tunnelling.
Introduction to the concept Applications or. Quantum spacetime. In mathematical physics, the concept of quantum spacetime is a generalization of the usual concept of spacetime in which some variables that ordinarily commute are assumed not to commute and form a different Lie algebra. The choice of that algebra still varies from theory to theory. As a result of this change some variables that are usually continuous may become discrete. Often only such discrete variables are called "quantized"; usage varies. The idea of quantum spacetime was proposed in the early days of quantum theory by Heisenberg and Ivanenko as a way to eliminate infinities from quantum field theory.
Physical reasons have been given to believe that physical spacetime is a quantum spacetime. Are already noncommutative, obey the Heisenberg uncertainty principle, and are continuous. Again, physical spacetime is expected to be quantum because physical coordinates are already slightly noncommutative. The Lie algebra should be semisimple (Yang, I.
Bicrossproduct model spacetime . Quantum mind. The quantum mind or quantum consciousness hypothesis proposes that classical mechanics cannot explain consciousness, while quantum mechanical phenomena, such as quantum entanglement and superposition, may play an important part in the brain's function, and could form the basis of an explanation of consciousness. It is not one theory, but a collection of distinct ideas described below. A few theoretical physicists have argued that classical physics is intrinsically incapable of explaining the holistic aspects of consciousness, whereas quantum mechanics can. The idea that quantum theory has something to do with the workings of the mind go back to Eugene Wigner, who assumed that the wave function collapses due to its interaction with consciousness.
The philosopher David Chalmers has argued against quantum consciousness. Description of main quantum mind approaches David Bohm In trying to describe the nature of consciousness, Bohm discusses the experience of listening to music. Efimov state. The Efimov effect is an effect in the quantum mechanics of Few-body systems predicted by the Russian theoretical physicist V. N. Efimov in 1970. Efimov’s effect refers to a scenario in which three identical bosons interact, with the prediction of an infinite series of excited three-body energy levels when a two-body state is exactly at the dissociation threshold.
One corollary is that there exist bound states (called Efimov states) of three bosons even if the two-particle attraction is too weak to allow two bosons to form a pair. The unusual Efimov state has an infinite number of similar states. In 2005, for the first time the research group of Rudolf Grimm and Hanns-Christoph Nägerl from the Institute for Experimental Physics (University of Innsbruck, Austria) experimentally confirmed such a state in an ultracold gas of caesium atoms. References Jump up ^ В.И. External links Quantum entanglement. Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently – instead, a quantum state may be given for the system as a whole. Such phenomena were the subject of a 1935 paper by Albert Einstein, Boris Podolsky and Nathan Rosen, describing what came to be known as the EPR paradox, and several papers by Erwin Schrödinger shortly thereafter. Einstein and others considered such behavior to be impossible, as it violated the local realist view of causality (Einstein referred to it as "spooky action at a distance"), and argued that the accepted formulation of quantum mechanics must therefore be incomplete.
History However, they did not coin the word entanglement, nor did they generalize the special properties of the state they considered. Concept Meaning of entanglement Apparent paradox The hidden variables theory
