The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

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 ...

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 ...

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

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 cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

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 ...

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 ...

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

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 ...
