On the scientific side, Sir Isaac Newton's guess for the age of the Universe was only a few thousand years. Einstein, the developer of the General Theory of Relativity, preferred to believe that the Universe was ageless and eternal. However, in 1929, observational evidence proved his fantasy was not to be fulfilled by Nature." And ever since that time, astologers have been convinced that since our cosmic neighbors appear to be disbursing into space, the Universe must have "started" about 15 billion years ago. AW C'MON - GIMME A BREAK. How Myopic can you get Even if the phenomenon was the result of a singularity which reached critical mass (and I maintain a strong skepticism of that) it doesn't mean the Universe is finite OR that it "began" when critical mass was achieved. Indeed, it is unlikely that ours would be the only such cosmic engine in the Universe. Consider this alternative explanation: Given a finite number of moving objects randomly vectored at random velocities within a finite volume, eventually all collisions which could occur WILL occur - within a finite period of time. Many of those collisions may occur outside of the original volume, but they will still take place within a finite period and within a finite distance. Once all collisions have occurred, all objects will eventually reach the boundary of the initial volume and except for those very few which may be moving at exactly the same velocity in precisely parallel paths, they will all be moving away from each other. The sound of galloping hooves does NOT mean the Unicorns are stampeding. PS: I use the term astologer correctly, for those who are convinced Big Bang "created" the universe on the strength of their associated observations are no more "scientific" than the average sooth sayer or oracle.
