From a mountaintop in Arizona, an army of robotic eyes has spent the last five years staring into the universe’s deep past.

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 ...

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 ...

One issue is that when scientists calculate what the Hubble constant should be, it doesn’t quite match observations of the ...

A new map of the cosmos, including more than 47 million galaxies and other cosmic objects, represents one of the most ...

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 cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

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 ...

Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely ...
