HBO's excellent 'His Dark Materials' finally gets 'The Golden Compass' right 2019-10-24T04:00:00Z The evidence is impressive, but I am still uneasy about details of the case for the cosmological constant, including possible contradictions with the evolution of galaxies and their spatial distribution. Making Sense of Modern Cosmology 2019-10-10T04:00:00Z If this is the case, calculating the cosmological constant involves dividing by the number of spacetime units in the universe, leading to a value much closer to what astronomers observe. The Cosmological Constant Is Physics’ Most Embarrassing Problem 2021-02-01T05:00:00Z Dr. Peebles utilized the cosmological constant, now known as dark energy, for a different reason: He aimed to show that the universe contained considerably less mass than was thought at the time.

A Craving for Aventure Drives This Modern-Day Renaissance Man 2016-10-07T04:00:00Z Why it matters The simplest explanation for dark energy is that there is a small force that acts in opposition to gravity, known as the cosmological constant. The dark universe: 4 big questions : Nature : Nature Research 2016-09-27T04:00:00Z In fact, Einstein invented the cosmological constant—literally by adding a constant to his famous differential equations—to explain how the universe resisted collapsing under its own gravity. A simple explanation of mysterious space-stretching ‘dark energy?’ 2017-01-10T05:00:00Z So through cosmological natural selection you’d get universes whose physical properties were more and more conducive to the evolution of intelligent life. Can Evolution Have a ‘Higher Purpose’? 2016-12-12T05:00:00Z If it's true it would be profoundly exciting, because it would show something's not right with the cosmological model. Q&A: Brian Schmidt : Nature : Nature Research 2016-09-27T04:00:00Z Others posit some kind of space-filling fluid, sometimes called quintessence, which acts a little like the cosmological constant, but slowly changes in density. Dark energy: Staring into darkness : Nature : Nature Research 2016-09-27T04:00:00Z A change would support quintessence, whereas a steady rate of expansion would be evidence for the cosmological constant. The dark universe: 4 big questions : Nature : Nature Research 2016-09-27T04:00:00Z The argument is mathematical, but essentially the tiny bit of energy that disappears in the universe leaves its trace by gradually changing the cosmological constant. A simple explanation of mysterious space-stretching ‘dark energy?’ 2017-01-10T05:00:00Z I don’t mean I buy the simulation scenario in particular, or the space alien scenario, or the cosmological natural selection scenario. Can Evolution Have a ‘Higher Purpose’? 2016-12-12T05:00:00Z In 1917, Einstein posited the idea of the cosmological constant — an adjustment to the general theory of relativity that amounts to assigning an energy value to empty space. Q&A: Brian Schmidt : Nature : Nature Research 2016-09-27T04:00:00Z For example, a theory might predict a new class of particles to curb the cosmological constant, and these particles might then be detected by the Large Hadron Collider at CERN, Europe's particle-physics laboratory.

New Milky Way Map Is a Spectacular Billion-Star Atlas 2016-09-14T04:00:00Z To see if Einstein's cosmological constant is right, we're attempting to show that it's fixed in time. Q&A: Brian Schmidt : Nature : Nature Research 2016-09-27T04:00:00Z According to general relativity, this cosmological constant would indeed oppose the force of ordinary gravity. Dark energy: Staring into darkness : Nature : Nature Research 2016-09-27T04:00:00Z This is line with results from the European Space Agency's Planck observatory, which concluded from cosmological evidence that there should only be three families of neutrinos in that mass range.

A simple explanation of mysterious space-stretching ‘dark energy?’ 2017-01-10T05:00:00Z "At the moment, this is the best measurement on the cosmological scale," Nichol says. Attempt to explain away ‘dark energy’ takes a hit 2016-07-19T04:00:00Z Einstein's cosmological constant always stays the same, so if the rate of expansion of the Universe doesn't reflect a constant energy for space, that would indicate the existence of something like quintessence. Q&A: Brian Schmidt : Nature : Nature Research 2016-09-27T04:00:00Z For now, that's a conclusion that seems to favour a candidate for dark energy known as the cosmological constant. Dark energy: Staring into darkness : Nature : Nature Research 2016-09-27T04:00:00Z So many theories and experiments in physics and astronomy rely on our ability to accurate model and measure cosmological parameters such as these.
