“The universe appears to us to exist in 3 dimensions of space and one of time — a geometry that we will refer to as the ‘3 dimensional universe.’ In our scenario, this 3-D universe is merely the shadow of a world with 4 spatial dimensions.Specifically, our entire universe came into being during a stellar implosion in this suprauniverse, an implosion that created a 3-D shell around a 4-D black hole. Our universe is that shell.”
