In the standard model of cosmology, dark energy currently accounts for almost three - quarters of the total mass - energy of the universe.

That goes against the standard model of cosmology, which says that the universe is increasingly uniform on larger scales, making it unlikely that structures big enough to produce such a tilt would form.

We got a value higher than the CMB measurement, but we need more systems to be really sure that something is amiss with the standard model of cosmology,» says Thomas Collett, an astrophysicist at the University of Portsmouth and a co-author on the new Astrophysical Journal paper.

It's supposed to be the «gold standard» of evidence supporting the standard model of cosmology — including dark matter, dark energy and the exponential expansion after the big bang known as inflation.

But according to the standard model of cosmology, the overall matter component should not be moving in any particular direction relative to the CMB.

Furthermore, the analysis of the Planck data also revealed small disruptions in gravity itself that are not completely consistent with the standard model of cosmology.

Their results demonstrate that the standard model of cosmology remains an excellent description of the universe.

The standard model of cosmology now assumes that a galaxy forms within a vast cloud or halo of dark matter.

Prior findings point to only six parameters that describe the development of the universe after the Big Bang with relative accuracy, using what is known as the standard model of cosmology.

Yet, the standard model of cosmology rests on the assumption that, on the largest scales, these variations are insignificant, and space is homogeneous and isotropic.

That's hard to judge, Challinor says, because there aren't compelling alternatives to the standard model of cosmology that predict exactly how an anisotropic universe should be.

According to the standard model of cosmology, when the universe sprang into existence, it contained a quantum field similar to an electric field that was roiled with quantum fluctuations.

Planck can measure the temperature of those microwaves, looking for a particular pattern predicted by the standard model of cosmology.

It also sensed tiny 1 - part - in - 100,000 variations in the CMB's temperature from point to point on the sky — traces of infinitesimal quantum fluctuations in the newborn universe that are essential to the standard model of cosmology.

The latest study of the afterglow of the big bang — the so - called cosmic microwave background radiation — confirms even more precisely the standard model of cosmology — and that's a victory for the theory — but it leaves researchers with no discrepancies that might point to a deeper understanding.

Now the duo say they know, and last week Beck presented the theory at a conference on unsolved problems for the standard model of cosmology held at Imperial College London.

The standard model of cosmology, called Lambda - CDM, includes two key ingredients.

That discrepancy could hint at «new physics» beyond the standard model of cosmology, according to the team, which includes physicists from the University of California, Davis, that made the observation.

«If you still see something when the error bars shrink, maybe it's new physics, beyond the Standard Model of cosmology,» Fassnacht said.

As Nobel Laureate Brian Schmidt explains in his 2016 lecture at the 66th Lindau Nobel Laureate Meeting: According to the standard model of cosmology, the universe is thought to have expanded exponentially right after the Big Bang and «things at the quantum scales were magnified to the universal scales, quantum fluctuations were expanded to the scale of the universe.»

These waves in turn are a central component Einstein's theory of general relativity from 1915, that is still the basis for today's standard model of cosmology.
