The mismatch between theory, which can predict other dimensions or spaces, and experimental physics, which is currently limited to determining objective facts in four-dimensional (4-D) space-time, is examined. There may be phenomena in other dimensions/spaces, which cannot be determined completely objectively. However, if results are reproducible,...

As far as we know the scientific search for the nature of reality in Europe started about 2500 years ago in ancient Greek. It was the ancient Greek philosopher Parmenides who reasoned that observable reality is created by an underlying reality. There are indications that the ancient Greek concept of the atom was (also) related to the proposed units...
