…travel through time.
Seriously. Some people want to go to Paris, some to the moon, I want to go to the 19th Century. Or maybe the 119th Century.
I’m not what you’d call a science fiction buff, but one TV show I liked was Doctor Who. The 20th Century version, not so much the 21st Century one. Before that, though, there was Peabody’s Improbable History.
There’s a theory that, rather than being infinite, the universe we live in is one of an infinite number of parallel universes. But you knew that, because I’ve told you about it, several times in fact. With apologies to Yogi Berra, it’s like déja vu all over again.
