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 ...

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 ...

The cosmological constant has plagued physicists for more than a century. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. There is a fundamental ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...

Why is the universe being ripped apart? It’s a question that has plagued astronomers since the discovery in the 1990s that the expansion of the universe is accelerating. The story is only further ...

In every bit of nothing, there is something. If you zoom in on empty space and take out all the planets and stars and galaxies, you might expect a pure vacuum, but you’d be wrong. In­stead you would ...

"The discovery of evolving dark energy would be as revolutionary as the discovery of the accelerated expansion of the universe itself, if confirmed." When you purchase through links on our site, we ...

On the list of tales we like to tell about Albert Einstein, the story of his "biggest blunder" is near the top. It begins with a problem that was bugging Einstein: How could his theory of general ...

Physicists including Robert H. Dickle and Fred Hoyle have argued that we are living in a universe that is perfectly fine-tuned for life. Following the anthropic principle, they claimed that the only ...
