A Wrinkle in Time, by Madeline L’Engle, opened the world of words and magic for me. Reading novels in general, entering the world of make-believe, allowed me to escape. It offered a place to go, one I could control, when the rest of the world felt out of control. Books fertilized my imagination to then fly free, filling me with wonder and hope in times of great need.

So how about that tesseract? In A Wrinkle in Time, Mrs. Who and Charles Wallace explain to Meg that they will be traveling by “wrinkling time” through a tesseract and that “the fifth dimension’s a tesseract. You add that to the other four dimensions and you can travel through space without having to go the long way around. In other words, to put it into Euclid, or plain (plane) geometry, a straight line is not the shortest distance between two points.

In the novel, the tesseract basically functions, more in modern science-fiction, as what called a space warp or a wormhole, a portal from one area of space to another which is possible through the bending of the structure of the space-time-continuum.

Then and now, utterly amazing stuff!
