Thoughts re. Relativity, a very short introduction (Russell Stannard)

Relativity - A Very Short Introduction The idea of reality being four-dimensional is strange and counter-intuitive. Even Einstein himself at first had difficulty accepting Minkowski’s suggestion – though later he was won over and declared ‘henceforth we must deal with a four-dimensional existence instead of, hitherto, the evolution of a three-dimensional existence’. Not that this is meant to imply that time has been reduced to being merely a fourth spatial dimension. Although it is indeed welded to the other three dimensions to form a four- dimensional continuum, it yet retains a certain distinctiveness. The light cone encircles the time axis, not the others. Absolute future and absolute past are defined in relation to the time axis alone.
