Cosmic biology may not just be possible, but inevitable
No one has ever discovered life in space, and given the enormity of the universe and our tiny, modest place in it, it’s entirely possible no one will—either in our lifetimes or for many lifetimes to come. But never mind, because life is out there—indeed, it’s everywhere, simply because chemically and mathematically it has to be there.
