A cacophony of articles on the possibility of the discovery of a parallel Universe were published last month in the wake of a New Scientist article … Whether this is due to dark matter or any other signal is unknown, as this experiment cannot account for the origin and magnitude of its background signal. The more granular your search is, the more likely you are to have a fluctuation you mistake for a signal. So scientists aren't about to contact parallel universes, and they weren't in 2015 either. This is an example of a statistical fluctuation, one of the 'red herrings' of experimental physics that can easily lead scientists astray. A representation of the different parallel "worlds" that might exist in other pockets of the... [+] multiverse, or anyplace else that theoretical physicists can concoct. If the team at Oak Ridge makes the same mistake, it's easy to see where this could lead. their controversial work on cold fusion. All Rights Reserved, This is a BETA experience. The experiment is assured to accentuate alarmist critics of the LHC, many of whom initially warned the high energy particle collider would start the top of our universe with the making a part of its own. Other, independent experiments disfavor the dark matter interpretation of DAMA's signal. Perhaps the unexplained positron excess detected by the AMS experiment means we're on the cusp of detecting dark matter; perhaps not. This suggestive result was significant at more than 3-sigma, but went away entirely with more data. The idea of a parallel universe is not new at all, and has been the basis of plenty of movies and TV shows over the decades. Although they were confident that what they had seen was a real fusion signal, their results could not be replicated, and subsequent investigations have failed to produce consistent results. Perhaps understandably, people are saying that this really is not the year for it, and, somewhat less understandably, believe that this might be what finally summons Cthulu. But it is entirely possible according to the strange rules of quantum mechanics. An article has been circulating around the Internet claiming that scientists at the Large Hadron Collider (LHC) are hoping to make contact with a "PARALLEL UNIVERSE" within days. We may have spotted a parallel universe going backwards in time. It is even probable that gravity from our own universe may “transfer” into this parallel universe, researchers at the LHC say. Or, as has been in the media lately, perhaps there's literally a mirror Universe out there, where the particles we know of are replaced with an exotic version of themselves: mirror matter. My two books, Treknology: The Science of Star Trek from Tricorders to Warp Drive, Beyond the Galaxy: How humanity looked beyond our Milky Way and discovered the entire Universe, are available for purchase at Amazon. But misattributing BICEP2's claimed polarization signal to gravitational waves rather than its true cause — galactic dust emission — is now a classic example of confusing signal with noise. One of the consequences of a Universe with mirror-matter is that some particles with the right properties — and the neutron is one of them — could oscillate into their mirror-matter equivalent. From the Higgs boson to dark matter and the parallel universe. Now, here's the real question: is this annual modulation evidence for dark matter? It would be interesting, though, if this led to a model of dark matter that could be tested by another, independent experiment. The signal strength we see is of the wrong magnitude to equate with 100% of the signal arising from dark matter, or from dark matter plus an expected background. The ATLAS and CMS diphoton bumps from 2015, displayed together, clearly correlating at ~750 GeV.... [+] This suggestive result was significant at more than 3-sigma, but went away entirely with more data. I am a Ph.D. astrophysicist, author, and science communicator, who professes physics and astronomy at various colleges. In all of these cases, as well as many others, it's important to get both the theoretical and the experimental work right. But we cannot assume that one of these explanations — the most conservative of explanations, mind you — must be at play. "This cannot be tested and so it is philosophy and not science.". The signals seen by LUX are consistent with background alone. In the endeavor of pushing our scientific frontiers, this is the one area that demands the highest level of skeptical scrutiny. This past May, a balloon flying over Antarctica sparked a worldwide interest in parallel universes. Opinions expressed by Forbes Contributors are their own. From a theoretical point of view, that means having a strong quantitative understanding about the expected signal that your new theory predicts as compared to the background signal that the prevailing theory predicts. "We predict that gravity can leak into extra dimensions, and if it does, then miniature black holes can be produced at the LHC.". You must understand what signals should be generated by both your new theory and the one it's seeking to supersede. Perhaps one was created at the same time as ours was, but where time runs backwards instead of forwards. It might seem like an exotic explanation, but if it's correct, it should lend itself to experimental signatures. But there are other signals that are far more ambiguous. Mirror matter and even a mirror Universe might be real, but if you want to make that extraordinary claim, you'd better make sure your evidence is equally extraordinary. The Fermions make up... [+] the left three columns; the bosons populate the right two columns. NASA scientists detect parallel universe 'next to ours' where time runs backwards An experiment in the frozen wastes of Antarctica has revealed evidence of a universe born in the same Big Bang as ours – but with rules of physics that are completely the opposite What could be tested is the existence of extra dimensions, if Faizal's paper in Physics Letters B is correct. You may have heard the thought experiment of Schrödinger’s cat, a spooky animal who lives in a closed box. Some scientists went further and said it should be producing around one miniature black hole per second. So, in the words of Kent Brockman from The Simpsons, is it time to crack each others' heads open and feast on the gooey bits inside? the astoundingly complex LHC “atom smasher” at the CERN center in Geneva, Switzerland, are fired up to its maximum energy levels ever in an endeavor to identify - or perhaps generate - tiny black holes. I am a Ph.D. astrophysicist, author, and science communicator, who professes physics and astronomy at various colleges. The most exciting is led by Leah Broussard at Oak Ridge National Laboratory, where they shoot neutrons at a barrier that should block them all, then look for neutrons on the other side. The Universe is out there, waiting for you to discover it. In a four-dimensional universe, you would need 1016 TeV of energy in order to produce the black holes, well beyond the capabilities of the LHC. In 1954, a young Princeton University doctoral candidate named Hugh Everett III came up with a radical idea: That there exist parallel universes, exactly like our ­universe. People have been captivated by news about a possible parallel universe — but there’s a big black hole in the theory expounded by a group of NASA scientists, according to a report on CNET. Although they were confident that what they had seen was a real fusion signal, their results could not be replicated, and subsequent investigations have failed to produce consistent results. Any time you get a positive signal from an experiment, you cannot simply take that signal at face value.
