Is transparent aluminum even remotely possible?

I think in the movie they said this, but I believe in the book, Scotty recognizes the name of the guy as the guy who DID invent transparent aluminum so he guessed he was supposed to give him the formula.

I also think they couldn’t use solid steel or other heavy things because the weight would screw up the sling shot calculations, or something.

Only if by “safe for cetaceans” you mean “inbred until they turn into chainsaw-wielding hillbilly cannibals” :slight_smile:

Except George & Gracie had just arrived in the 23rd century, and wouldn’t know that their species was extinct or even that they’d just traveled through time. And at the start of the movie, Spock speculates that the Whale Probe’s so advanced that their civilization doesn’t recognize humans as an intelligent life form worth worrying about (“I find it illogical that its intentions could be hostile”) which does kinda go against the patently obvious pro-environmental message of the movie, go figure.
