well i know im wrong somewhere so show me where...

couldnt we calculate the size of the universe by taking the speed of light and the estimated age of the universe (14.5 billion years) and consequently use 14.5 billion light-years as a radius and put it into the old spherical volume equation (4/3 * pi * r3)
