If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a ...

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

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

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 ...

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 ...

Black holes are eaters of all things, even radiation. A new study published in Physical Review Letters suggests that black ...

The inflationary epoch that caused our universe to rapidly expand in its earliest moments may be connected to the modern era of dark energy, thanks to a phantom component of the cosmos that changes ...

A physicist has proposed a new approach to solving one of the biggest theoretical problems in physics: the cosmological constant. The cosmological constant, introduced a century ago by Albert Einstein ...

Einstein's 1917 paper, "Cosmological Considerations in the General Theory of Relativity," applied general relativity to the universe as a whole, establishing a firmer basis for cosmology. To create a ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The widely accepted theory at the present moment ...
