Space Sounds: The Music of the Cosmos

Posted on May 28, 2021 in Gresham College, Outreach, Public lecture, Science, universe

A Gresham College lecture as Visiting Professor of Cosmology, part of the series “The Unexpected Universe“. “In space, no one can hear you scream”. The chillingly accurate tagline of Ridley Scott’s 1979 space horror classic, Alien, is often belied in science fiction movies, forgetting that in space there is no air, and hence no sound. Space today […]

Understanding the Universe with AI

A Gresham College lecture as Visiting Professor of Cosmology, part of the series “The Unexpected Universe“.

A Gresham College lecture as Visiting Professor of Cosmology, part of the series “The Nature of Reality“. Albert Einstein’s mind-boggling ideas revolutionized our view of the universe.
