A Travel Guide for Fun Dimension

The center of the large sphere will be yours. You will be able, as you would expect from our current three-dimensional reality: you can move left, right, forward, back, up, or down. We ask you to remain still while our 4-D BOOST technology, which propels you from any point on the sphere’s surface at once, lifts you into the fun dimension.

used to understand four-fun dimension space

Cubes can be used to understand four-dimensional space. Let’s take, for example, a 1-D line segment. We can create a (2-D square by adding a parallel segment to it and connecting it with two other perpendicular segments that are equally sized. So far, Similar to the previous example, if you take two squares parallel and connect them with perpendicular segments, you get a (3D) cube. Here’s where it gets tricky. The next iteration will use two parallel cubes and perpendicular connectors to create a 4-D hypercube or tesseract.

We are 3-D creatures and can’t understand the 4-D structure. William Thurston, a mathematician and the late William Thurston believed that this is because our brains are wired to handle linear, analytical information in one place and geometric shapes in another. We can solve equations that have four or more variables with ease, which allows us to imagine and manipulate objects in higher dimensions. However, our brains are not able to see them. Matt Parker, an Australian mathematician and stand-up comedian, explains that the fun dimension is “kind of imaginable as right angles to three dimensions we have.” “But we can’t imagine the fun dimension.”

You’re saying that I can’t view photos of my hotel before getting there?

Unfortunately, no. However, you can get a glimpse into the fun dimension by using an optical illusion called Necker cube (labeled below as A). This shape can be interpreted in two ways: it can be viewed as a box slightly left-and-down (B) or its mirror image (C). The Necker cube appears to be rotating in a manner that craigslist kauai mathematician Rudy Rucker calls “twinkling rearrangement.” At some point, this twinkling could appear as one continuous motion. Rucker notes in Geometry, Relativity, and the Fun Dimension that “this motion cannot be continuous if there is a 4-D rotation.” This is because a rotation of three dimensions can’t produce an image mirroring. Perhaps we can create a 4-D phenomenon with our minds!
