"diameter" of universe
Can anyone explain how estimates of the diameter of universe are as high as something like 50 billion light-years while the age is about 12-13 billion light years (13 x 2 would seem to give diameter of 26)? Is this a function of the fact that the universe (especially during inflationary period) is expanding more rapidly than the speed of light in vacuum? How is this figure measured, or is it calculated?
Thanks, Howard
