Famed theoretical physicist and cosmologist, Stephen William Hawking died today. A giant in his field and popular culture, Hawking was among the first to set out a theory of cosmology explained by a union of Einstein‘s General Theory of Relativity and the realm of quantum mechanics. CBS This Morning asked famed physicist and CBS News science and futurist contributor, Dr. Michio Kaku to honor Hawking‘s life and discuss how his work has advanced our understanding of the universe.

Early last year, scientists made a breakthrough discovery of gravitational waves in the wild, signaling the dawn of a new subfield of astronomy. This week, separate observatories in Washington, Louisiana, and Italy independently detected and collectively confirmed more gravitational waves in the wild — this time from the collision of two black holes about 2 billion light-years from Earth. Gravity waves pick up cosmic events that are invisible or nearly impossible to measure by any other means. By combining observations of a single event using multiple means, it’s now possible to gain a more complete understanding of the source’s properties than ever before. This method is called multi-messenger astronomy. CBS NEWS science and futurist contributor, Dr. Michio Kaku, joins CBSN to break down what this discovery means for the future of astronomy. WATCH NOW!
