Mostly harmless
I’m not familiar with the books, and the plot summary of their Wikipedia article does not mention nuclear propulsion whereas the article for the series does, so I went with that.
Unless what bothers you is the x followed by the apostrophe and the s, which I never know when to omit the s, so it is what it is.
It’s not uncommon in scifi. Netflix’s Three Body Problem also explores such a solution in quite some depth.
Buzz Aldrin will turn 94 in a couple of weeks.
“Sir” goes with first name or full name, e.g. Sir Isaac or Sir Isaac Newton, but never Sir Newton.
How do aliens view Australia then?
Maybe, this sentence, out of context. The rest of the post makes it abundantly clear that the ages of these things go:
mountains -> bones -> dinosaurs
The poster may either be a victim of Poe’s Law, in which case their “joke” wasn’t very funny, or they could be making the logical deduction as you describe but as a mistake. I thought it was the latter.
The original sentence is consistent with the assertion that the mountains had formed before the first boney ancestors of dinosaurs evolved. This is also consistent with the presented timeline.
The correction would mean that the mountains may be older or younger than dinosaurs, because they are only older than bones, and the article is deafeningly silent on the issue of whether dinosaurs had bones.
It’s a failure of literacy on the poster’s part, hence the downvotes.
You didn’t queue up twice when they were handing out verbal reasoning skills…
It’s probably from an hour long portrait interview, in which they cover a lot of ground including favourite English literary pieces, and the interviewer tries to tie it to the guest. They would probably ask David Beckham which Harry Potter character he’d have on his football team.
