Yeah, um, I think so, but ... one of us is likely the ancestor of the other in some way, and I can't tell which!!
Dang confusing time machines!!
By the way, I knew a fella, Larry Niven, who had a WHOLE hole collection -- one each of every kind of hole you can imagine!!
Yep, you guessed it. He added one too many, and lost the hole shebang down the event horizon. Too bad, too, cause that one special kind of hole makes a great garbage disposal -- not meaning to bring politics into the discussion, however.
Holes can be very useful but also dangerous if used unwisely. Never stack your holes.
Nothing is more manageable but also has some inherent dangers. I once left some nothing laying on top of something and ended up with nothing. Nothing can be stacked with nothing or something but nothing always needs to be placed under something rather than vice versa.
