The famous Albert Einstein developed the theory of relativity back in 1905. Since then, most scientists had the idea that the mysterious fourth dimension simply had to do with time. However, recently, two teams of experts, one in the United States and the other in Europe, have claimed that there is also a fourth spatial dimension. According to Mikael Rechtsman, this 4D spatial system doesn’t physically exist. However, 4D quantum hall physics can be accessed through this lower-dimensional system. The experts are now thinking about creating physics in the higher dimension which they can then use to make devices. These devices could then be used to access the higher-dimensional physics in the lower dimensions.
It’s worth noting that 3D objects are known to cast 2D shadows. Following the same system, 4D objects should cast 3D shadows, even if we cannot yet perceive the object. The two teams of experts conducted two special experiments which have brought them the 2016 Nobel Prize for Physics and three other Nobel prizes for theoretical and experimental work.
The mysterious fourth dimension
The effect the two teams have obtained through the experiments takes place in the area between two materials. There, the electrons can only move in two dimensions. In order to change the behavior of the electrons you need to produce a magnetic field in a 90-degree line to the 2D plane. When increasing the voltage and reducing the temperature, this effect can be manipulated even further. Scientists know this as the Lorentz force which is able to deviate electrons.
During the second experiment, they supercooled atoms near absolute zero. Then, using lasers, they created a 2D lattice and placed them inside it. One of the researchers, Michael Lohse, said that the two experiments were very interesting and complimented each other. It’s interesting that after these experiments, scientists can take into account phenomena from four or more dimensions as something that exists.
