A 4D object should then cast a 3D shadow. We can learn something about a 3D object by studying its shadow. So it stands to reason that we could also gain knowledge about a 4D object from its 3D shadow. Both teams in these experiments did something of that kind.
They used lasers to catch a glimpse of the 4 th dimension. The results of each experiment were published in two reports , both in the journal Nature. In the European experiment, scientists took the element rubidium and cooled it down to absolute zero. In the US experiment, glass was used to control the flow of laser light into the system.
This was basically a rectangular glass prism with a series of channels within it, which looked like a number of fiber optic cables stuck inside, running the length of the box and terminating at both ends. Researchers were able to manipulate the light using these channels as wave guides, in order to make it act like an electric field. When light jumped from opposite edges into the corners, researchers knew they had observed the quantum Hall effect, as it would occur in a 4D system.
Researcher Oded Zilberberg was among them. He said that before these experiments, observing actions occurring in the 4 th dimension seemed more like science fiction. Yet, physics in the 4 th dimension could be influencing our 3D world.
In the next, scientists believe it might be interesting to see what happens when they do. Rechtsman claims we could gain a better understanding of the phases of matter by investigating the 4 th dimension. The concept is so far removed from our experience that it is hard to imagine what they could be like. We have, however, already seen the ghostly effects of four-dimensional space touch on our own and wired up electric circuits with an extra dimension.
It is unlikely to stop there. Now we have got the hang of it, there is talk of creating five, six or even more dimensions, and even suggestions that exotica such as new particles might lurk in the extra-dimensional wilderness.
This is a frontier that we are barred from exploring directly. We are forced instead to look for the subtle imprints that extra dimensions make on the three dimensions we are confined to. Even so, we could be about to extend the boundaries of reality in ways that come close to the limits of our descriptive powers.

The real thing will be way more awesome.
Parker also recommends key chains with his favorite 4-D shape: a hypercube turned inside out, known as a hyperdiamond or octacube. It can only exist in four dimensions because it must pass through itself without making a hole. However, you may want to save your money.
