Sagan's portrayal of the alien message and the subsequent events feel so plausible yet profound. I wonder what real scientific theories or ideas influenced this depiction.

The tension between belief systems is central to the story, and I’d love to hear if others felt more aligned with one side or the other after reading.

Sagan was a scientist as well as an author, so I’m curious whether the narrative sacrifices some scientific detail for drama or vice versa.
