Big Bang Breakthrough Team Back-Pedals On Major Result

Posted by samzenpus on from the no-bang dept.

An anonymous reader writes A few months ago researchers announced they had discovered proof of the big bang. Now they're not so sure. Further research suggests cosmic dust might have skewed the results. "Back in March, the BICEP2 team reported a twisted pattern in the sky, which they attributed to primordial gravitational waves, wrinkles in the fabric of the universe that could have been produced when the baby universe went through an enormous growth spurt. If correct, this would confirm the theory of inflation, which says that the universe expanded exponentially in the first slivers of a second after the big bang – many believe that it continues to expand into an ever-growing multiverse. Doubts about the announcement soon emerged. The BICEP2 team identified the waves based on how they twisted, or polarised, the photons in the cosmic microwave background (CMB), the earliest light emitted in the universe around 380,000 years after the big bang. Other objects, such as the ashes of exploding stars or dust within our galaxy, can polarise light as well."

      You cannot have spacetime expanding or contracting in flat space; the observed metric expansion of space is an *enormous* violation of the flat space metric. So, you're on good grounds with "the speed limit may not apply", except for two things. Firstly, there is every reason to believe (via searches for Lorentz invariance) that our universe is locally Poincaré invariant, where local means in the limit in which spacetime intervals go to zero or alternatively in the local section of the fibre bundle or alternatively in the local region of a point. In fact, Poincaré invariance holds up extremely in much larger regions, which is one reason practically everyone who uses GR will switch to SR in the weak field limit for the sake of the much easier mathematics and for ease of reasoning (cf. the various don't-use-GR-to-solve-the-twin-paradox arguments from e.g. Baez (who advocates reducing it to SR by introducing pseudogravitational fields)). Secondly, except in certain null dust solutions, it is generally considered poor form to introduce GR observers who do not move along timelike geodesics (I'll use "FTL" as shorthand). It is certainly *plausible* that one could construct a metric which takes into account observers who move on spacelike geodesics, but if it were physical, then you are stuck with the choose-no-more-than-two-of-SR-FTL-and-causality. (There are arguments that one could alternatively abandon logic (Bell) or accept superdeterminism (`t Hooft) instead). Even as an investigation, GR-with-FTL-observers will lead you into analytical approximate solutions at best (probably -- if you do better, you should get recognition); relating that to gauge theory and QFTs will be even harder.

      The Alcubierre metric is fully locally Lorentz invariant. There are no FTL observers in the sense above. It can be looked at as a test theory of particular numerical methods on 3+1 foliations, which is Alcubierre's principal area of study (he literally wrote the textbook). He often uses it to probe at corner cases (and possible weaknesses) in both ADM and BSSN and especially the software used in 3+1 modelling. It has also been used to raise questions about semiclassical gravity.

      Finally, for completeness, the "democratisation of causal cones" comes up from time to time, most recently in the context of FTL neutrinos. Carroll deals with that at http://blogs.discovermagazine.... and emphasises the point that what one worries about it “closed spacelike curves on which physical particles move". What he does not say is that the ratio between the speed of light and the maximum attainable speed of any physical particle should be identical in any theory with local Lorentz invariance (and indeed in Special Relativity); this is well-tested against both SME (in the SR case) and PPN (in the GR case). While theorists would love to play with observers on timelike geodesics, there is not one iota of evidence to suggest that any such observer exists.

      How does spacetime know how fast something is going through it? If there is nothing else other than spacetime and a single photon, what regulates the photon's speed? What is the speed relative to?

      The easiest way to answer that is by saying you're thinking about it incorrectly. Our every day experiences leads us to believe that distances are absolute. That time periods are absolute. And if we're talking about the relative speeds in human experience, that's a very, very good approximation.

      Turns out reality is weirder. It's not that spacetime "knows" how fast something is traveling through it. It's that space and time don't behave like our senses lead us to believe. So, from our perspective, if energy to use to accelerate a ship wasn't a problem, and we're here on Earth observing it head someplace 10 light-years away, the very earliest that ship will get to its destination will be just over 10 years, as no matter how much energy is used to accelerate it, it's going to just asymptotically approach c, but never reach it.

      However, the thing is, it's not really a speed-limit, of how you would think of it. From the perspective of the people on the ship, if energy isn't a problem, you can get to your destination as quickly as you want. Under 10 years? Sure. You can get there in under a second (we'll assume we've figured out how to ensure everyone won't die from accelerating from 0 to close to c, then back to 0 again all within a second). You can get there in a millisecond. If you put more energy into acceleration, you can always get there faster. However, you still never go faster than light. It just so happens that, as you accelerate, you disagree with the people on Earth about how far your destination is. It used to be 10 light-years away, but now, after that huge acceleration, it's only 100 meters away, and you can cover that small distance really quickly at near the speed of light. To you, an infinitesimally small amount of time has passed. To the people on Earth, over 10 years.

      TL;DR; It's not that that spacetime is preventing you from going faster, it's that spacetime is a 4-D Minkowsky space, and we're approximating it as a 3D Euclidean space + time in everyday life. That's a great approximation, until you start going really fast. Then it's just not good anymore.

      Humanity is going to be stuck until it embraces and accepts the FACT that we are G-d's children and are created in His image.

      You mean we created God in our own image-- we're fuckups, so God must be a fuckup.

      I mean, how else can you be omniscient, omnipotent, and omnibenevolent yet somehow create a world that isn't what you wanted?

    "A few months ago researchers announced they had discovered proof of the big bang"

    They were actually looking for evidence of cosmic inflation, as this would account for how the universe is isotropic, or the same over vast distances, something big bang doesn't account for.

    Bing Bang theory, personally, I am not very convinced of the latter. There's so much mystery to solve. Furthermore, I'd like to invit you to visit the website https://play.google.com/store/... in which, you can follow scoops about cigarette electronique. Thanks for sharing

    How best to study the Big Bang? Make a Little Bang in the laboratory! Perhaps we will discover that the optimal conditions for the Big Bang arose when someone began to devise practical laboratory experiments to study and understand the previous one. Ad infinitum.

  28. Good that it was "unconfirmed" back then by Blaskowicz · · Score: 1

    I remember that at the time this was annouced, and especially in slashdot and the linked article we were told to take the story with a grain of salt. Oh well, seems the slashdot blurb didn't but the article included : “These results are as extraordinary as they get, and they will require the most extraordinary scrutiny,” Kamionkowski said. (...)

    Maybe slashdot comments were better at pointing out these were initial, preliminary etc. results. The general media failed to put any nuance and announced the find as fact, sure. (even some science vulgarization publications)
