1 Answer. The total US domestic market is 629,457,532 scheduled passengers per year. It is true that Delta carried the most total passengers in 2010, but that includes BOTH international and domestic passengers. For domestic only, Southwest was the largest carrier in the US.
A universe where the very laws of nature are different â for example, one in which there are no Laws of Motion â would in general count as a parallel universe but not an alternative reality and a concept between both fantasy world and earth.
The three possible types of expanding universes are called open, flat, and closed universes. If the universe were open, it would expand forever. If the universe were flat, it would also expand forever, but the expansion rate would slow to zero after an infinite amount of time. If the universe were closed, it would eventually stop expanding and recollapse on itself, possibly leading to another big bang.
