On human timescales, the universe may as well be eternal. It’ll be here long after our species and our planet are gone, but ...

If ultimately true, the universe will reach its maximum size around 11 billion years from now. At that point, physics (and ...

A Cornell physicist calculated new data from dark energy reviews, indicating the end of the universe within a few billion years in the future.

For centuries, humanity has pondered the ultimate fate of the universe. From theories of infinite expansion to the concept of ...

The cosmological constant, which explains how and why the universe is expanding, has been previously described by astrophysicists as “the worst prediction in the history of physics” due to its ...

Researchers propose that black holes may emit dark energy, possibly explaining the universe's accelerating expansion.

The universe's expansion is accelerating, a phenomenon attributed to dark energy, potentially explained by a cosmological constant (Λ) in Einstein's general relativity. The ΛCDM model, the standard ...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself ...

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 ...

Scientists know very little about the mysterious force dubbed “Dark Energy” that seems to be quickening the expansion of the universe but, according to LSU Physics and Astronomy Associate Professor ...

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 ...

We’ve grown up with the idea that the universe will expand forever, meaning the "cosmological constant" is positive. What if it's negative?
