About this Event
New Scientist presents ...On-demand Event: What We Still Don't Know About Black HolesChris Impey, professor of astronomy, University of Arizona
Last year the first image of a black hole made headline news around the world. In this recorded online lecture, leading astronomer Chris Impey explains why black holes occupy a special place in modern science and in the public mind.
He reveals why the idea of an object with gravity so strong that even light can’t escape begins with general relativity; how Stephen Hawking transformed our understanding of black holes; and why theorists still struggle to understand the singularity and what happens to information that falls into the event horizon.
Discover how astronomers plan to use black holes, large and small, to test general relativity in new ways. And why despite recently entering an exciting era with the detection of gravitational waves from merging black holes and even the first image of a black hole, these enigmatic objects are still not ready to give up all their secrets.
Chris’s inspiring and fascinating lecture, is followed by a Q&A where participants of the live event were able to ask him questions about black holes.
What's included in your ticket:
- Chris Impey's 40 minute lecture followed by a Q&A
- Exclusive access to two additional 40-minute lectures filmed at our Instant Expert masterclass on the Universe
- Bonus content from New Scientist including a printable map of the Milky Way, home to supermassive black hole Sagittarius A*
About the speakers:
Chris Impey is a University Distinguished Professor of Astronomy and Associate Dean of the College of Science at the University of Arizona.
He has over 180 refereed publications on observational cosmology, galaxies, and quasars, and his research has been supported by $20 million in NASA and NSF grants. He has won 11 teaching awards and has taught two online classes with over 180,000 enrolled and 2 million minutes of video lectures watched.
A prolific author, his latest book is Einstein’s Monsters: The Life and Times of Black Holes.
The event was hosted by Valerie Jamieson, New Scientist events' Creative Director .
Ticket purchasers also get exclusive access to the following two lectures recorded at an Instant Expert masterclass on the Universe:
What Happened at the Big Bang, Eugene Lim, King’s College, London
The big bang model is the paradigmatic theory of how the universe began. In this talk, Eugene Lim talks about why, despite our confidence in the model, it is still too early to declare that we have solved the problem of the universe's origins.
The Search for Cosmic Particle Accelerators , Susan Cartwright, University of Sheffield
Somewhere in the universe, something is accelerating elementary particles to energies far higher than anything the physicists at CERN can even dream of. We see the products of these astrophysical accelerators as cosmic rays, and have been observing them for over a century - but, unfortunately, as the galaxy's magnetic field scrambles their directions, we still have very little idea of where these super-energetic processes are taking place.
Our best hope is to look at uncharged messengers, such as very high-energy photons and neutrinos, which are unaffected by magnetic fields and therefore point back to where they came from. In this talk, Susan Cartwright looks at what these messengers tell us about the very high energy universe.
