I would like someone to compute this simple formula and express their opinion to its validity: At the moment of the first cause (popularly known as the big bang- a hateful misnomer) space itself expanded at the rate of 6 million miles per second according to one theoretical estimation (traveling faster than light because it being the inertial frame against which light travels). The age of the universe according to another theoretical estimation (by gauging the age of stars) is approximatly 13 billion years. Now with space itself traveling at 6 million miles a second for 13 billion years that would put the size of the universe on a much vaster scale than currently assumed. Now one could argue that spatial expansion is slowing due to the "frictional" effects of mass and gravity. But it is also safe to assume that the universe is much larger than the visible universe. Just because light can only have traveled 13 billion years in the time since the beginning of the "first cause" does not mean there is nothing beyond the range of visibility. In fact, by my, admittedly amateur, calculations the size of the physical universe is at least twice or three times the size of the current visible universe.
