Dimensions, subject Index

"The Universe appears to exist in three dimensions of space and one of time; this is a geometry that we refer to as the 'three dimensional universe.' in our scenario, this three-dimensional universe is merely the shadow of a world with four spatial dimensions. Specifically, our entire universe came into being during a stellar implosion in the suprauniverse, an implosion that created a three-dimensional shell around a four-dimensional black hole. Our Universe is that shell."

"First, our ideas are not idle speculation – they are firmly grounded in the mathematics that describe space and time."

"The second reason that out four-dimensional universe is worth thinking about is because a close study of this universe could help us understand deep questions about the origin and nature of the cosmos."
