Here is the conventional theory on the date and size of the universe:

That the universe dates back 13.7 billion years. Its radius, then, is the distance a beam of light would have traveled in that time … 13.7 billion light years. That works out to about 1.3 quadrillion kilometers. In fact, it’s even bigger…. Much bigger. How it got so large, so fast, was until recently a deep mystery.

That the universe could expand had been predicted back in 1917 by Albert Einstein, except that Einstein himself didn’t believe it until he saw Hubble and Humason’s evidence. Einstein’s general theory of relativity suggested that galaxies could be moving apart because space itself is expanding.

However, this video examines the notion that the universe may in fact be older than 13.7 billion years.  What do you think?  Feel free to comment with your theories!
