Certain that the world will soon descend into nuclear war, a brilliant scientist goes into cryogenic suspension for a million years, hoping to awaken in a more enlightened time. Instead the world quickly retreats from war and advances rapidly. By the time he awakens, most humans have left Earth, and the few remaining are being rounded up to serve as conscripted soldiers in an alien war.; An aging space pilot is mocked for his slow ship, but when an invading armada approaches Earth his ship is the first to see it. His warning allows Earth to beat back the invasion, making him a hero and the commander of a new space patrol.; The 5th dimension is the dream dimension. The creatures there are trying to pass into this dimension, but belief in their existence as opposed to surmising a mere dream experience disrupts the structure of the dream dimension and forces the creatures to withdraw from our world. The narrator sells his story to Strange Tales to encourage readers to believe in the creatures and frustrate their invasion aspirations.; Two scientists try to travel to the future, but arrive in the stone age. They believe they have proved travel into the future impossible, not suspecting that they actually saw the world after the destruction of civilization by war.; An old eccentric in a wheelchair hires a sea captain to take him to a spot where he believes that the lost continent of Atlantis lies. When they reach their destination he reveals himself to be a merman and thanks the sailors for bringing him home before diving overboard.
