Why We May Be Surrounded by Older Alien Civilizations

Are alien civilizations likely to be younger or older than us in age? A basic question that seems insurmountable until we start detecting them. But even before that, we can use some logical deduction using lifetime distribution statistics to determine the most plausible answer to this question. Join us today for an explanation of our new research paper on this topic.
