单词 | scalar field |
例句 | A scalar field gives the value of a physical quantity. College Physics for AP Courses 2015-08-12T00:00:00Z To do that, researchers add to a theory like general relativity an additional, tunable field called a scalar field. To explain away dark matter, gravity would have to be really weird, cosmologists say 2020-11-20T05:00:00Z We postulated the existence of a “scalar field,” a non-directional variable force in spacetime, he says, that is essentially the same as the one responsible for inflation, but which penetrates into the present epoch. Physicists Claim Universe 'Rings' Like Crystal Glass 2015-06-29T04:00:00Z Why would you prefer something like a scalar field over the cosmological constant? Dark Energy Discernment Dithers over Quantum Jitters or an Undetected Field 2014-10-01T04:00:00Z "This puts some very serious constraints on these rolling scalar field cosmologies." Right Again, Einstein! New Study Supports 'Cosmological Constant' 2013-01-17T17:45:00.223Z This mechanism introduces a complex scalar field, leading to the prediction of a scalar particle: the SM Higgs boson. [Article] A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider 2012-12-20T21:26:32.063Z Set things up just right and at large spatial scales, the scalar field interacts only with itself and acts like dark matter. To explain away dark matter, gravity would have to be really weird, cosmologists say 2020-11-20T05:00:00Z Ringermacher notes that this scalar field is possibly the cause of the oscillations. Physicists Claim Universe 'Rings' Like Crystal Glass 2015-06-29T04:00:00Z Called a "scalar field," it works just as well as G in describing the way the universe works, except that mathematically, unlike the constant, its strength is allowed to vary in time and space. What If There Were No Gravity? 2012-01-10T16:15:20.327Z But he notes that in some sense it merely replaces one mysterious thing—dark matter—with another—a carefully tuned scalar field. To explain away dark matter, gravity would have to be really weird, cosmologists say 2020-11-20T05:00:00Z Dialing down the scalar field to zero everywhere would essentially flatten the universe.
