The Earth and Time,outhwards (the converse is true for people living in the southern hemisphere). More commonly known is the phenomenon of a ship travelling away from the shore disappearing from view whilst its sails are still visible above the horizon. The sails are then seen to ‘sink’ below the horizon as the ship further recedes.注视 发表于 2025-3-28 10:41:44
