 And welcome back, George Norrie with Michael Shermer. Michael, this is a vast universe. Your thoughts on whether we're alone in it or not? I think the aliens are probably out there somewhere for sure. We're not alone. It would be stunning if we were just crunching the numbers through a direct equation kind of algorithm where you have hundreds of billions of galaxies, maybe as many as a trillion galaxies, each of which has hundreds of billions of stars.
