Caspian Sea

This is a big sea. A very big sea. A very very big sea. A huge and gigantic sea. An enormous sea, whose shortest distance across can't be crossed at light speed in a life time. It is amazingly massive, and brilliantly huge. Even trying to think about one ninety-millionth of its size can result in your brain being splattered across thirty billion galaxies (which of course, is not nearly as wide as the Caspian sea).

However, it is not nearly as big as the GOPSEA.
