the astronaut effect

1. When someone is talking about something so advanced you hardly understand 50% of it, but the subject is so interesting, you keep listening and encourage the speaker to continue talking.
2. When someone is smart and has interesting things to tell.

"Did you understand anything of what he said?"
"Not really"
"So why did you keep asking questions?"
"I don't know, the astronaut effect I guess"

Or

"Do you like that guy?"
"I don't know, he's sweet, works hard, but he's missing the astronaut effect ."
