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

For decades, cosmologists have had an awkward number sitting at the center of their equations. The universe is expanding, and ...

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 ...

Physicists at Brown University suggest that the universe’s topology could explain why the cosmological constant — the energy driving cosmic acceleration — is far smaller than quantum theory predicts.

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

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 ...

At the heart of the Big Bang model of cosmic origins is the observation that the universe is expanding, something astronomers have known for nearly a century. And yet, determining just how fast the ...
