A very informative and educational podcast!
Dr Pam seems goofy and too silly to take a science podcast serious. She regularly doesn’t actually know what she talks about. DEI hire? Broken speech. Doesn’t know her info. Unprofessional and seems to be looking for Crain To fill in her ignorance. Get a real professional. She’s not smart.
Was the first podcast I ever listened to….. and it’s still just as fantastic approaching 800 episodes. Thanks to you both for teaching me so much about something I love learning about so much.
Thin content, frequent commercial breaks
I listen to this show because I enjoy hearing your insights on astronomy. It is very unprofessional, unhelpful, and unnecessary to waste airtime complaining that your political candidate didn’t win the recent presidential election. Please work through your personal issues, and stay on point. (Ref: Ep 743)
