Astronomers have just completed the largest high-resolution three-dimensional map of the universe, including more than 47 ...

The far distant fates of the Universe offer a number of possibilities, but if dark energy is truly a constant, as the data indicates, it will continue to follow the red curve, leading to the long-term ...

The long-standing problem of the cosmological constant, described both as “the worst prediction in the history of physics” and by Einstein as his “biggest blunder”, is being tackled with renewed ...

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 ...

A comprehensive new study combines decades of research to reveal that we're missing an essential component in our ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...

The going theory among cosmologists is that the universe will eventually rip itself to shreds owing to its ever-accelerating rate of expansion. Not so, say a pair of physicists who have just taken it ...

The original version of this story appeared in Quanta Magazine. Physicists have deduced subtle hints that the mysterious “dark” energy that drives the universe to expand faster and faster may be ...

The Dark Energy Spectroscopic Instrument (DESI) has completed the most comprehensive 3D map of the universe ever created, ...
