In the interview with Jill Tarter, I found myself surprised by the amount of uncertainty. There is such a wide range of frequencies that extraterrestrial communication could be found on that it has led to false signals of extraterrestrial life. It seems really difficult to parse out what is normal and what may indicate extraterrestrial life.
This made me wonder what the false signals look like. I know from my astronomy class that there are tons of different frequencies just bouncing around the universe, from background microwaves to X-rays, so I'd love to hear more about the science behind it. Additionally, what about the possibility that extraterrestrial life operates on a frequency that we don't know about yet or in a way we can't recognize yet? Would that be a possibility?
