We can never 100% prove that the constants really are constant. There is a set of very special numbers, known as the fundamental constants of nature, that cannot be explained. Where do they come from?

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

(CNN) — New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.
