The Forum - Peering into Space
Space science from the Aspen Ideas Festival in Colorado. Ed Lu hunts for deadly asteroids, Lisa Randall probes the dark matter, and Craig Hogan measures the bandwidth of reality.
NASA astronaut and asteroid-hunter Edward Lu explains why we urgently need to map all sizeable Near-Earth orbit asteroids if we want to avoid becoming 'dinosaur toast'. Lisa Randall, a theoretical physicist at Harvard, explores the mysteries of dark matter, the invisible, seemingly inert stuff which is thought to account for over a quarter of all mass-energy in the universe. And Fermilab's Craig Hogan is behind a new experiment to probe the fabric of space itself, by seeing if it's possible to detect the very tiniest units in the universe.
