Isaac Asimov Memorial Debate
In his memory, the Hayden Planetarium is honored to host the annual Isaac Asimov Memorial Debate: a panel series generously endowed by relatives, friends and admirers of Isaac Asimov and his work. The Isaac Asimov Memorial Debate brings the finest minds in the world to the Museum each year to debate pressing questions on the frontier of scientific discovery. Proceeds from ticket sales of the Isaac Asimov Memorial Panels benefit the scientific and educational programs of the Hayden Planetarium.
Asimov Debates 2001-2009
2001 Asimov Debate: The Theory of Everything
Can the entire Universe be explained with a single, unifying theory?
This is perhaps the most fundamental question in all of science, and it may also be the most controversial. Albert Einstein was one of the first people to envision a unified field theory that might describe the behavior of all matter and energy in the cosmos with a single stroke of the pen; however, a definitive solution has eluded physicists to this day. As we enter the twenty-first century, the leading candidate for a theory of everything appears to be string theory, which considers every particle in the Universe as a multi-dimensional entity—a string—that manifests itself in our Universe differently depending on how it twists and vibrates.

A diverse panel of outspoken scientists offered insight into the latest research in this field, including newest evidence from the Martian meteorite known as ALH84001, up-to-date information on sub-surface liquid water currently on Mars and Europa, Earth's thriving population of extremophiles (organisms that live in environments previously thought inhospitable), and the search for extrasolar planets.

2003 Asimov Debate: The Big Bang
The Big Bang Theory remains the most successful idea ever presented for cosmic origins.
Legendary is its capacity to describe the observable Universe, from its first three minutes through the present day. Still, some aspects of this model remain puzzling. Dark matter and dark energy, for instance, test the limits of our cosmic understanding.
Now alternative theories of cosmic origins challenge the fundamental notions of the Big Bang. The latest ground-based and space-borne telescopes are observing the cosmic microwave background with unprecedented precision. Armed with this new generation of data, we may begin to favor one theory of the Universe over the others.
Panelists
- Alan Guth—Professor of Physics at MIT; pioneer of inflationary cosmologies, which proposes that the expansion of the Big Bang was propelled by a repulsive form of gravity, where the very early Universe experienced a rapid, exponential growth in size; author of The Inflationary Universe: The Quest for a New Theory of Cosmic Origins.
- James Peebles—Professor of Physics at Princeton University; proponent of the classical Big Bang cosmology and a keen observer of the subject's rich and diverse history; author of the graduate texts Principles of Physical Cosmology, and The Large Scale Structure of the Universe.
- Lee Smolin—Researcher at the Perimeter Institute for Theoretical Physics; author of Life of the Cosmosand, co-inventor of loop quantum gravity, the leading approach to the quantization of space and time, and inventor of cosmological natural selection, a testable hypothesis that may explain the values of the fundamental constants in nature.
- David Spergel—Professor of Astrophysics at Princeton University; he is the member of the science team for the Wilkinson Microwave Anisotropy (WMAP) satellite, which recently announced the latest and most precise measurements ever made of the cosmic microwave background radiation.
- Paul Steinhardt—Professor of Physics at Princeton University; a theorist and a pioneer of inflationary cosmologies, he recently introduced the new cyclic theory of cosmic origin which is an explanation for the origin of the Universe that exploits recent developments in string theory. This novel idea has received extensive attention as one of the few viable competing theories to the Big Bang.

2005 Asimov Debate: The Enigma of Alien Solar Systems
When the first planets were discovered around other stars nearly a decade ago, everyone expected these alien solar systems to resemble our own, with small, rocky planets close to their host star and larger, gaseous planets farther away. However, not one of these planetary systems holds these properties. Currently, these systems contain one or more Jupiter-sized planets orbiting as close to their host stars as Mercury orbits our Sun. These systems stump observers and theorists alike forcing us to look anew at our own Solar System and ask the question, Are we the enigma?

2006 Asimov Debate: Universe - One or Many?
A panel of cosmologists debated possibility that our Universe is just one of many comprising the multiverse.

2007 Asimov Debate: The Pioneer Anomaly
The Pioneer spacecraft, two identical unmanned planetary probes, were launched in the early 1970s on trajectories that would send them past the outer planets and onward with enough speed to leave the Solar System entirely—a first in space exploration. While attempting to account for all known forces that act on these craft, scientists analyzed the telemetry signals from the craft and found an inconsistency. The positions of the craft do not match the scientists' predictions. There seems to be an extra force at work, not included in the analysis, which has affected the motion of these craft across decades of monitoring their signals, from launch until their last contact.
The big questions are: What is this force? Is it an unforeseen glitch of spacecraft design? Is it a sign of the discovery of new physics or a new understanding of gravity? Or simply of something in our present knowledge of physics that has been overlooked?

2008 Asimov Debate: Mining the Sky
Planets, moons, asteroids, and comets contain natural resources such as water, minerals, and trace elements that may have survival value to visiting astronauts and economic value to life on Earth. How did we learn of these materials? How would one go about mining them? Who owns these resources, if anyone? And should they be mined at all?
