There are billions of planets in the Universe that, theoretically, can support life. But so far, we haven't discovered any aliens out there. Maybe the reason is we're just looking in the wrong places. What if alien life isn't anything like the life we know of? What if it doesn't need water? Or oxygen? What if it can withstand incredibly hot temperatures? Or very acidic environments? And what would we need to search for to finally find it?

Join us on an imaginary adventure — grounded in scientific theory — through time, space and chance, as we ask what if some of the most fundamental aspects of our existence were different.
