The Hubble Constant is a Measure of the Increase in the Energy of the Universe

We postulate the universe to be the three dimensional surface volume of an expanding, hollow, four dimensional hypersphere, called the hyperverse. Using current measurements, we find that a hyperverse, whose surface volume matches the volume of the observable universe, has a radius of 27.7 billion light years, giving a radial expansion rate of twice the speed of light, and a circumferential expansion rate that matches the Hubble constant. We show that the Hubble constant is a measure of the increase in the energy of the universe, implying the hyperverse surface, our universe, is composed of energy. The 2c radial expansion both sets the speed limit in the universe, and is the basis of time. The hypersphere model provides a positively curved, and closed universe, and its 2c radial expansion rate, and circumferential expansion rate matching the Hubble expansion, give strong support that the universe is the 3D surface volume of an expanding 4D hypersphere.
