Was the titanic the largest ship on earth?
She was, but her window was narrow. A German vessel, the Imperator, was due to surpass her within about a month of her sailing.
In Greek Mythology, the Titans were powerful god's called the "elder god's" that ruled the earth. They were overthrown by the Olympians. A Titan was a symbol of mightiness and power. The White Star Line chose the name Titanic due to it being the largest ship in the world at the time of its launching. "Titanic" is the only official name of the ship.
Titanic was heavier than any other ship of the time, thus making it the largest ship in the world. It had a NEARLY identical sister ship called the Olympic, which was the same size, but several tons lighter. Therefore, Titanic was the biggest ship in the world, because it was heavier than any other ship.
