Physicists May Have Evidence Universe Is A Computer Simulation

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.

Police in North Carolina Patrol in a Corvette The nonpolice version of the Corvette Z06. Speeders in Wake County, N.C., will have to go pretty fast if they want to outrun the police department’s latest interceptor — a Chevrolet Corvette Z06. The Wake County police recently seized the Corvette from a drug dealer, said David Cooke, the county manager, according to the News & Observer. Predicting the unpredictable: Critical analysis and practical implications of predictive anticipatory activity 1Department of Psychology, Northwestern University, Evanston, IL, USA2Dipartimento di Psicologia Generale, Universita di Padova, Padova, Italy3Department of Statistics, University of California at Irvine, Irvine, CA, USA4Samueli Institute, Alexandria, VA, USA5Consciousness Research Laboratory, Institute of Noetic Sciences, Petaluma, CA, USA A recent meta-analysis of experiments from seven independent laboratories (n = 26) indicates that the human body can apparently detect randomly delivered stimuli occurring 1–10 s in the future (Mossbridge et al., 2012). The key observation in these studies is that human physiology appears to be able to distinguish between unpredictable dichotomous future stimuli, such as emotional vs. neutral images or sound vs. silence. This phenomenon has been called presentiment (as in “feeling the future”). In this paper we call it predictive anticipatory activity (PAA).

Quantum biology: Do weird physics effects abound in nature? 28 January 2013Last updated at 00:05 GMT By Jason Palmer and Alex Mansfield BBC News and BBC Radio Science Unit The multi-billion-dollar fragrance industry might just benefit from the ideas in quantum biology Disappearing in one place and reappearing in another. Physicists To Test If Universe Is A Computer Simulation Physicists have devised a new experiment to test if the universe is a computer. A philosophical thought experiment has long held that it is more likely than not that we're living inside a machine. The theory basically goes that any civilisation which could evolve to a 'post-human' stage would almost certainly learn to run simulations on the scale of a universe.

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.

Egocide and suicide | The Psychology of Me Lately, I’ve been thinking about egocide. (Why does my autocorrect want to change that to “geocode”??) I’m at the end of my rope and climbing back up is not an option. I’ve got to change. Drastically change. The Sacred, Spherical Cows of Physics - Issue 13: Symmetry Early in their training, many physics students come across the idea of spherical cows. Cows in the real world—even at their most plump and well-fed—are hardly spherical, and this makes it tricky to calculate things like, say, how their volume or surface area scales with their height. But students learn that these numbers are easy to calculate if they assume the cow is a perfect sphere, or in other words, that it has spherical symmetry. The lesson: Hard problems become easier when certain underlying (though approximate) symmetries are enforced. The lessons of the spherical cow don’t end with the undergraduate classroom, though. They extend to the very forefront of physics.

Quantum entanglement isn't only spooky, you can't avoid it Quantum entanglement is the key to quantum computing, cryptography, and numerous other real-world applications of quantum mechanics. It is also one of the strangest phenomena in the Universe, overcoming barriers of space and time and knitting the entire cosmos into an integrated whole. Scientists have long thought that entanglement between two particles was a rare and fleeting phenomenon, so delicate that exposure of the particles to their surroundings would quickly destroy this linkage. Now mathematicians at Case Western University have shown that entanglement between parts of large systems is the norm, rather than being a rare and short-lived relationship.

Quantum black hole study opens bridge to another universe 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. This is Why I'll Never be an Adult I have repeatedly discovered that it is important for me not to surpass my capacity for responsibility. Over the years, this capacity has grown, but the results of exceeding it have not changed. Normally, my capacity is exceeded gradually, through the accumulation of simple, daily tasks. But a few times a year, I spontaneously decide that I'm ready to be a real adult. I don't know why I decide this; it always ends terribly for me.

Wormhole Photon Time Travel - Casimir Energy, Messages The basic principle behind the Search for Extra-Terrestrial Intelligence (SETI) is that we’re better off hearing from extraterrestrial intelligence than we are not hearing from extraterrestrial intelligence, but—even assuming we don’t catastrophically screw up first contact (and we may)—we have no guarantee that the alien civilization we reach will share any of our history, values, or priorities. But there’s one alien civilization we can count on to share at least some traits in common with us: the Earth of the future. And having learned of Cambridge physicist Luke Butcher’s discovery this week that Casimir energy may be able to keep a wormhole open long enough to send photons back in time, I have one question: why the heck would we want to do that?

What the Hell Are Tachyons? Tachyons cause a lot of problems in movies with starships, but they also cause problems for people in real life. Specifically, they cause problems for students of relativity and string theorists. Learn about the ins and outs of tachyons, and why they need extra dimensions. Whenever the Borg come jumping out of a wormhole in space, go ahead and blame tachyons. Whenever temporal distortions mean an older version of you has come back to scold the younger version of you, blame tachyons. Whenever an ancient vessel gets a boost across a galaxy, and re-starts an ancient war, blame tachyons. Laws of physics vary throughout the universe, new study suggests A team of astrophysicists based in Australia and England has uncovered evidence that the laws of physics are different in different parts of the universe. The team -- from the University of New South Wales, Swinburne University of Technology and the University of Cambridge -- has submitted a report of the discovery for publication in the journal Physical Review Letters. A preliminary version of the paper is currently under peer review. The report describes how one of the supposed fundamental constants of Nature appears not to be constant after all. Instead, this 'magic number' known as the fine-structure constant -- 'alpha' for short -- appears to vary throughout the universe.
