For a quarter century, cosmologists have treated dark energy as a fixed, featureless pressure that steadily drives galaxies ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...

"The discovery of evolving dark energy would be as revolutionary as the discovery of the accelerated expansion of the universe itself, if confirmed." When you purchase through links on our site, we ...

According to physics, the universe and everything in it can be explained by just a handful of equations. They’re difficult equations, all right, but their simplest feature is also the most mysterious ...

It is dangerous to bet against Einstein. Cosmological research shows that the rate at which the Universe expands is increasing, rather than decreasing as had previously been thought. The concept of ...

Dark energy, which forms almost three-quarters of the universe, is the most mysterious stuff known to man. A new set of Chandra X-Ray Observatory data, however, has given scientists good information ...

Those of you who know my writing will know that I don’t use many analogies. Analogies have a very useful place in helping people understand difficult concepts, but they also have a tendency to be a ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn.
