Do we live in a computer simulation? UW researchers say idea can be tested

Do we live in a computer simulation? UW researchers say idea can be tested
News releases | Research | Science December 10, 2012 A decade ago, a British philosopher put forth the notion that the universe we live in might in fact be a computer simulation run by our descendants. The concept that current humanity could possibly be living in a computer simulation comes from a 2003 paper published in Philosophical Quarterly by Nick Bostrom, a philosophy professor at the University of Oxford. The human species is likely to go extinct before reaching a “posthuman” stage.Any posthuman civilization is very unlikely to run a significant number of simulations of its evolutionary history.We are almost certainly living in a computer simulation. He also held that “the belief that there is a significant chance that we will one day become posthumans who run ancestor simulations is false, unless we are currently living in a simulation.” Eventually, more powerful simulations will be able to model on the scale of a molecule, then a cell and even a human being.

Whoa: Physicists testing to see if universe is a computer simulation | The Sideshow Could this be a computer simulation? ( Will you take the red pill or the blue pill? Some physicists and university researchers say it's possible to test the theory that our entire universe exists inside a computer simulation, like in the 1999 film "The Matrix." In 2003, University of Oxford philosophy professor Nick Bostrom published a paper, "The Simulation Argument," which argued that, "we are almost certainly living in a computer simulation." Researchers at the University of Washington agree with the testing method, saying it can be done. So how, precisely, can we test whether we exist? "This is the first testable signature of such an idea," Savage said. The testing method is far more complex. To translate, if energy signatures in our simulations match those in the universe at large, there's a good chance we, too, exist within a simulation.

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. And if it has? And it's not just theory. READ MORE: Physicists Have Evidence Universe Is Computer Simulation Now another team have devised an actual test to see if this theory holds any hope of being proven. Professor Martin Savage at the University of Washington says while our own computer simulations can only model a universe on the scale of an atom's nucleus, there are already "signatures of resource constraints" which could tell us if larger models are possible. This is where it gets complex. And if such signatures do appear in both? Zohreh Davoudi, one of Savage's students, goes further:

Physics News :: Is it real? Physicists propose method to determine if the universe is a simulation Living In The Lattice Beane et al via arXivA team of researchers is going down the theoretical rabbit hole with a test to find out if our universe is nothing more than a computer program. We don't want to alarm you, but there's a distinct possibility that our universe is nothing more than a huge computer simulation, that we're all living in The Matrix, and none of this is real. But while stopping short of full-on human-machine warfare, a team of interested researchers at the University of Bonn is trying to see just how deep the rabbit hole goes by performing a measurement that should tell us if we're stuck in a computer simulation. This notion is based on quantum chromodynamics, which is the idea that describes how the strong nuclear force binds quarks and gluons together into protons and neutrons--and thus binds everything else together. Physicists may prove we exist in 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.

Quantum Reality: The Limitless Potential Within Everything Nobel Prize winning physicists have proven beyond doubt that the physical world is one large sea of energy that flashes into and out of being in milliseconds, over and over again. They have proven that thoughts are what put together and hold together this ever-changing energy field into the ‘objects’ that we see. Think of a movie reel. A movie is a collection of about 24 frames a second. A TV tube is simply a tube with heaps of electrons hitting the screen in a certain way, creating the illusion of form and motion. Think of television. This is what all objects are anyway. Each of these senses has a specific spectrum (for example, a dog hears a different range of sound than you do; a snake sees a different spectrum of light than you do; and so on). In other words, your set of senses perceives the sea of energy from a certain limited standpoint and makes up an image from that. All of our interpretations are solely based on the ‘internal map’ of reality that we have, and not the real truth.
