Link to Through the wormhole (S2): 4- Are there more than three dimensions? documentary
Documentary Description
For most of our history, we’ve rested easy in the notion that there were three dimensions that have existed throughout time: length, width and height. Ah, the good old days. In the early 20th century, Hermann Minkowski and Albert Einstein connected our comfortable three dimensions with a fourth, time, defining special relativity using a space-time continuum.
This kind of worked, but still didn’t explain a troublesome new theory of gravity called quantum mechanics that arose around the same time Minkowski and Einstein were working on their theories. Quantum mechanics had its own rules that contradicted the concepts behind the space-time continuum. Scientists treated this incompatibility like the weather for decades, discussing it but not really doing anything about it.
