"Van Stockum was an early twentieth century physicist from the Netherlands. Handsome chap, but sadly he died in World War Two during a bombing raid. Anyway, he did some of the early work on Einsteins General theory of relativity. One of the things he came up with was the concept of a world line in a Lorentzian manifold. Twisted up space to you and me." She stirred a copious amount of sugar into her coffee. "Also known as a closed timelike curve."
"Look lady, I haven't got a clue what you're talking about. Just... What the hell is going on?!"

I'm now a 'frontseater' for this lesson! Will I get a diploma at the end?

Sorry about the double posting, Jeff. Following a comment of Frenchie's earlier, I did a Google search to check out van Stockum for myself. I'm impressed. If it was me, van Stockum would have been some bullshit geezer I had made up. I really am very interested now as I was once a scientist. Aiming for an A+ :-)

Thanks Neville. Bo problems with the double-post. It's happened to me as well. I can't guarantee any grades at the end. Causality might get in the way 😉

Bo? I meant "No" Wish we could edit our own comments.
