The tesseract is real
I never knew there was actually such a thing as a tesseract.
When I was a youngster, I always tried to read the books that my older brothers were reading. We read a lot of sci-fi type of stuff, I remember. Madeline L’Engle’s A Wrinkle In Time was one book that got passed around. I don’t remember the storyline at all, but what I always did remember was the tesseract. In the book, tesseract was the term for making the ‘wrinkle in time’ that could transport you super-far instantly. All you have to do is fold space-time so that your location and where you want to go are right next to each other. Then you just hop over, and you’re there. An interesting concept to be sure. We’re going to have to figure out how to do that one day, it sounds useful. I mean we’re going to have to get across those billions of light-years somehow.
mathworld.wolfram.com sets the matter straight. “The tesseract is the hypercube in R^4, also called the 8-cell or octachoron. It has the Schläfli symbol {4,3,3}, and vertices (+/-1,+/-1,+/-1,+/-1).”
I have no idea what that means, but there is a nifty 3-D interactive tesseract at http://mathworld.wolfram.com/Tesseract.html
After all this time, to find out that a tesseract is a real thing… ha.
Who knew?
