We show that a 3-sphere, whose surface volume matches the volume of the observable universe, has a radius of 27.6 billion light years, meaning it would be expanding into the fourth dimension at exactly twice the speed of light. We claim this observation has deep significance. Although the whole universe is much larger than this 'observable hyperverse', the 2c expansion rate is the actual expansion rate we experience, and this is due to the increase in the duration of the unit of quantum time as the universe expands. A model of the universe based on the 2c radial expansion rate produces equations stating that both energy and matter are continuously created with expansion, starting at the time of the Big Bang. Placing these equations into the Friedmann equation also gives a constant rate of expansion. The continuous creation of matter and energy, starting with the Big Bang, is distinct from the Steady State model, which has no Big Bang. The universe as an expanding 3-sphere is not an FRW model, as energy and matter both change with one over the scale factor squared. This negates most arguments against constant-rate expansion, as they are based on the FRW model. A 2c-hyperverse cosmology provides a new, powerful model for exploring the nature of the universe.
