Transcript: The conventional assumption about life in the universe is that it exists on a terrestrial planet around a Sun-like star in the habitable zone, the region of distance where liquid water can exist on a planet’s surface. but we know within our own solar system that the habitable zone must extend to include the moons of the giant planets. In the larger scales of the universe, there may be many more suitable habitats for life if all it requires is an energy source and thermal disequilibrium. Low mass stars and brown dwarfs are far more common than Sun-like stars. Free floating planets might even exist in space, and this forms a huge set of potential sites for life. We have no idea whether planets form readily around brown dwarfs. The first planets ever detected were actually around a pulsar, a dead husk of a star that had gone supernova and left a compact core. We don't know if planets could hold life around a pulsar because there is no energy source. In the wilder speculations of theorists, it’s even surmised that life could potentially exist on the surface of a pulsar itself, working under the extreme gravity and perhaps with a vastly accelerated evolutionary clock. This is pure speculation, but with the subject of life in the universe we reach the edge of the scientific method. Induction cannot be implied when we do not understand how strange life might be elsewhere in the universe.
