...time is not a single dimension of spacetime but rather a local geometric distinction in spacetime. While this may seem esoteric, it is actually quite simple, according to the author of a new book due out soon ... riiiight!
Imagine that 'the arrow of time' in the Universe, like gravity on Earth, is ostensibly the "same" everywhere, yet at the same 'time' it is different everywhere relative to everywhere else. That means that the 'arrow of time' points in different directions in spacetime depending on where you are, so time has a geometry just like space has a geometry.
The idea is that there are an infinite number of time dimensions in the Universe - which revolutionizes gravitational theory and much of modern science with it. A number of outstanding scientific mysteries are definitively solved, including observations...
