Cosmology’s neat story of a universe driven apart by a simple, invisible “cosmic fuel” is starting to fray. A growing body of ...

Dark energy is one of the most mysterious concepts in all of the cosmos. We know very little about what it is but it just might play an overwhelming role in the death of the universe. Often referred ...

For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every dot is a galaxy. DESI collaboration and KPNO/NOIRLab/NSF/AURA/R ...

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 ...

Do you know what connects Edwin Hubble’s theory for an expanding universe and Albert Einstein’s cosmological constant? The ...

As I finished my PhD in 1992, the universe was full of mystery – we didn’t even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of ...

The original version of this story appeared in Quanta Magazine. Physicists have deduced subtle hints that the mysterious “dark” energy that drives the universe to expand faster and faster may be ...
