LISA - the Laser Interferometer Space Antenna - will be humanity's first gravitational wave detector in space, launching in 2035. Unlike ground-based detectors like LIGO, LISA's three spacecraft will form a massive triangle 2.5 million kilometers on each side, allowing it to detect gravitational waves from entirely new sources.
Joined by Dr. Tamara Bogdanovic, astrophysicist at Georgia Tech, we explore how LISA could revolutionize our understanding of the cosmos. From detecting the primordial gravitational wave background - giving us a window into the universe just 10^-32 seconds after the Big Bang - to potentially discovering new physics beyond Einstein's general relativity.
The conversation covers LISA's incredible engineering challenges, what makes space-based detection superior to ground-based, and the revolutionary science it could unlock. We touch upon how it might confirm or challenge our theories of cosmic inflation, reveal exotic physics impossible to study in any laboratory, and open entirely new frontiers in gravitational wave astronomy.
From the technical details to the wildest discoveries LISA might make, this episode explores one of the most ambitious scientific projects ever attempted.
