The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...

The cosmological constant, originally introduced by Einstein as a measure of vacuum energy density, has re-emerged as a central challenge in understanding the observed accelerated expansion of the ...

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 ...

""For nearly a century, physicists have been searching for a way to reconcile gravity with quantum mechanics. The Substrate Theory offers a principled approach that derives both from the same ...
