Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, estimating the universe’s age. This collaborative effort unites various ...

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 ...

Dark energy remains among the greatest puzzles in our understanding of the cosmos. In the standard model of cosmology called the Lambda-CDM, it is accounted for by adding a cosmological constant term ...

The standard cosmological model known as Lambda-CDM (ΛCDM) proposes that dark energy is a constant force in the universe. However, an early “hint” in a new detailed map from the Dark Energy ...

Robert Nichol is a member of the Dark Energy Survey collaboration. Dark energy is estimated to make up nearly 70% of the observable universe, yet we still don’t understand what it is. While its nature ...
