I recall that Kant said the same thing more than 200 years ago.
Well, Kant said that there were three dimensions of space, and that that was all there could be, since it was clearly the case that there couldn't be any others.
Special Relativity blew a hole in that. General Relativity nailed the coffin shut. Quantum Field Theory and String Theory are currently dancing on the grave.
In fact, many believed that Euclid’s was the only geometry that the human mind was capable of knowing. Immanuel Kant, the influential eighteenth-century philosopher, taught that Euclidean geometry was ordained to be true by the very structure of the human intellect; space could not even be conceived to be otherwise. Therefore, Kant concluded, Euclidean geometry was an example of synthetic a priori knowledge—it was a truth about the world that could be known to be true without doing any experiments.
Kant, of course, was all wet, but many people believed him anyway Carl Friedrich Gauss, however, saw through Kant’s overconfidence.
Gauss, the greatest mathematician since Newton, realized that geometry could, logically, be construed in a way different from Euclid’s. Unfortunately Gauss was a perfectionist, who was therefore reticent about publishing...
