What If The Cosmological Constant Is NOT Constant? - Episode 26

Overview

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger.

But a recent survey of primordial sound waves frozen into the way galaxies are sprinkled through the universe reveals that this fate is now in question.
