Lol you can't say the moon collided with earth, get told that actually, something hit earth to form the moon, and then say "exactly" haha

And the Theia collision may be a significant source of the water on earth, but it's definitely not certain. Some people think that comet and asteroids had already contributed most of the water on earth before that happened, but that also isn't too certain.

It's terrifying and I read it all in one night because I couldn't stop. It's a nightmare.

My favorite rapper has "do not resuscitate" tattooed across his forehead.

I'm not usually a fan of face tats, but I can get behind that one because it leaves no question.

No problem! I also recommend Heinlein, Vinge, Niven, Verne, Wells, and Asimov of course.

Heh, I have quite a few pet peeves, like affect/effect and saying there's instead of there're when referring to plurals. But I've spent some time making sure my students know that there is no such thing as 100% certainty for things existing in the universe. But then, you can say "I'm 100% certain that one does not equal two" and that's true, so it's more about being conscientious of the language you use to describe reality.

One of the best books I've ever read. There isn't some crazy conflict, just scientists exploring something for the most part. Plus there are three more that show what's actually happening.

If you remember oumoaoa, that thing that came into our system from interstellar space and was rotating like it would if it was hollow inside and needed to provide centrifugal gravity... You'll see how everyone who read Rama was kinda secretly bugging out.

I also recommend Childhood's End, also by Clarke and imo his coolest book. It's short and seriously great, one of the best endings of anything I've read.
