Black holes are gravitational behemoths that dramatically twist space and time. Recently, they’ve also pointed researchers to a remarkable proposal—that everything we see may be akin to a hologram. Alan Alda joins Kip Thorne, Robbert Dijkgraaf and other renowned researchers on an odyssey through one of nature’s most spectacular creations, and learn how they are leading scientists to rewrite the rules of reality.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

Lucie Green takes us on a journey from the centre of the sun to planet earth in a run-down of the latest solar physics research.

Lucie's book "15 Million Degrees: A Journey to the Centre of the Sun" is available to buy now - https://geni.us/2oB8V

110 times wider than Earth; 15 million degrees at its core; an atmosphere so huge that Earth is actually within it: come and meet the star of our solar system.

Light takes eight minutes to reach Earth from the surface of the Sun. But its journey within the Sun takes hundreds of thousands of years. What is going on in there? What are light and heat? How does the Sun produce them and how on earth did scientists discover this? Since the Royal Institution was founded in 1799 our knowledge of the Sun has changed dramatically and much of the work was carried out at the Ri.

Join Lucie Green for an enlightening talk, taking you from inside the Sun to its surface and to Earth, to discover how the Sun works, how a solar storm can threaten the modern technology that society relies on and more of the latest research in solar physics.

Lucie Green is a Professor of Physics based at the Mullard Space Science Laboratory, UCL’s Department of Space and Climate Physics. She studies activity in the atmosphere of our nearest star, the Sun. In particular, she looks at immense magnetic fields in the Sun’s atmosphere which sporadically erupt into the Solar System.

Lucie is very active in public engagement with science, regularly giving public talks and appearing on TV shows like Sky at Night.
