I will be rereading the story I mentioned and I will not have a problem with the science. I could have easily had some questions in 1950. Nobody knew for sure but the gaseous nature of Jupiter was firmly theorized by scientists

Suspending disbelief has never been a problem for me. I am a zombie fiction fan. :)

However, if the fiction is old it gets a pass, but you would surely admit that no self respecting science fiction writer would have humans landing on the surface of Jupiter. I would have a problem with that today.

Larry Niven wrote a gas giant novel called The Integral Trees that propped a human colony living in huge trees in an oxygen rich layer of a gas giant.

I'll be looking forward to reading the Vonnegut novel it sounds great
