Numbers speak. [Img Src ] Once upon a time, nosotros had problems inwards the foundations of physics. Then nosotros solved them. That was forty years ago. Today nosotros pass most of our fourth dimension discussing non-problems. Here is i of these non-problems. Did y'all know that the universe is spatially almost flat? There is a discover inwards the cosmological concordance model called the “curvature parameter” that, according to electrical current observation , has a value of 0.000 plus-minus 0.005. Why is that a problem? I don’t know. But hither is the storey that cosmologists tell. From the equations of General Relativity y'all tin calculate the dynamics of the universe. This agency y'all larn relations betwixt the values of observable quantities today too the values they must accept had inwards the early on universe. The contribution of curved shape to the dynamics, it turns out, increases relative to that of thing too radiations every bit the universe exp...

I conduct maintain a headache and blame Nature mag for it. For almost fifteen years, I conduct maintain worked on quantum gravity phenomenology, which agency I written report ways to experimentally bear witness the quantum properties of infinite together with time. Since 2007, my query surface area has its ain conference series, “Experimental Search for Quantum Gravity,” which took house most late September 2016 inwards Frankfurt, Germany. Extrapolating from whom I personally know, I gauge that almost 150-200 people currently operate inwards this field. But I conduct maintain never seen nor heard anything of Chiara Marletto together with Vlatko Vedral, who only wrote a comment for Nature  magazine complaining that the query surface area doesn’t exist. In their comment, titled “ Witness gravity’s quantum side inwards the lab ,” Marletto together with Vedral telephone telephone for “a focused coming together bringing together the quantum- together with gravity-physics commu...

Srsly? Several people asked me to comment on a newspaper that is hyped past times phys.org every bit a examination of quantum gravity . I’ll brand this brief. First things first, why are you lot nonetheless next phys.org? Second, the newspaper inward inquiry is on the arXiv too is titled “ a real like newspaper was inward 2012 . It is right that noncommutative geometry plays a purpose inward many approaches to quantum gravity too it’s non an alone uninteresting idea. However, the variant that the authors desire to examination inward the newspaper is non of the usually discussed type. They desire the final result to move relevant for the center-of-mass coordinates, too then that it scales alongside the full mass. That supposition has no back upward from whatever approach to quantum gravity. It’s made-up. It is besides mathematically highly problematic. Third, I already spelled out in my review several years ago  that this is bogus (see department 4.6) too doesn’t follow...

Think imitation tidings too echo chambers are a work alone inwards political discourse? Think again. You give away many examples of myths too falsehoods on pop scientific discipline pages. Most of them surroundings the hype of the day, only some of them receive got been repeated therefore oftentimes they immediately seem inwards papers, seminar slides, too textbooks. And many scientists, I receive got noticed alongside alarm, genuinely believe them. I can’t say much almost fields exterior my specialty, only it’s obvious this happens inwards physics. The claim that the bullet cluster rules out modified gravity, for example, is a peculiarly pervasive myth . Another ane is that inflation solves the flatness problem , or that in that place is a flatness work to get with. I lately constitute some other myth to add together to my list: the assertion that the cosmological constant is “the worst prediction inwards the history of physics.” From that this catchy only incorrect declaration...

They utter close me. Grumpy Rainbow Unicorn. [ Image Source. ] And I can’t blame them. Because cipher else is happening on this planet. There’s simply me in addition to my examine to convince physicists that beauty isn’t truth. Yes, I know it’s non much of an insight that pretty ideas aren’t ever correct. That’s why I objected when my editor suggested I championship my book “Why Beauty isn’t Truth.” Because, duh, it’s been said earlier in addition to if I wanted to live on stale I could convey written close how we’re all made of stardust, aah-choir, chimes, fade in addition to cut. Nature has no obligation to live on pretty, that much is sure. But the truth seems difficult to swallow. “Certainly she doesn’t hateful that,” they say. Or “She doesn’t know what she’s doing.” Then they explicate things to me. Because sure as shooting I didn’t hateful to tell that much of what goes on inwards the foundations of physics these days is a waste materials of time, did I? And fifty-fift...

Collider quilt. By Kate Findlay. [ Image: Symmetry Magazine ] Nigel Lockyer, the manager of Fermilab, recently spoke to BBC virtually the benefits of edifice a adjacent larger particle collider , i that reaches energies higher than the Large Hadron Collider (LHC). Such a novel collider could mensurate to a greater extent than exactly the properties of the Higgs-boson. But that’s non all, at to the lowest degree according to Lockyer. He claims he knows in that location is something novel to regain too: “Everybody believes there’s something there, but what we’re right away starting to inquiry is the scale of the novel physics. At what publish energy does this novel physics present up,” said Dr Lockyer. “From a simple calculation of the Higgs’ mass, in that location has to endure novel science. We simply can’t surrender on everything nosotros know equally an excuse for where nosotros are now.” First, allow me notation that “everybody believes” is an declaration advertizement pop...
