According to the equations that govern black holes, the larger one of these cosmic behemoths is the lower its average density ...

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

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

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

Image: When a large nearby object, such as a galaxy, blocks a distant object, such as another galaxy, the light can detour around the blockage. But instead of taking a single path, light can bend ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...

The true “informational age” of the cosmos may be 62 billion years, not just the 13.8 billion years of our current expansion.

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

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...
