Initial State of the Universe

Although in the human context, what kind of signals are alien signals? According to my first calculation, the source of alien signals is the same as the Internet of people and computers. For example, onwkwonp is a greeting representing alien signals. It's not that the alien signal is a kind of interference information, but it's just a strong and emotionless statement that's hard to describe. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
