Exploring the Mysteries of Dark Energy and Cosmic Growth in SWaB's Latest Podcast.

Astrophysicist Karolina Garcia discusses the composition and growth of the Universe, which is 13.8 billion years old and composed of a mix of normal matter and radiation, but is dominated by dark matter and dark energy on the largest of cosmic scales.

Multiple, independent lines of evidence point to the same consensus picture of the Universe.
