Could it be that the universe is just too vast for ETs to make contact? Or are aliens avoiding us on purpose because they’ve seen what humans are like? John and Jamie geek out over Corbet’s new paper, which suggests the reason we haven’t picked up any alien signals might be much more mundane than we think.
