Scientists have found an unexpected culprit for the Titanic's sinking: the moon, Reuters reported.
Greenland icebergs of the type that the Titanic struck generally become stuck in the shallow waters off Labrador and Newfoundland, and cannot resume moving southward until they have melted enough to re-float or a high tide frees them, Donald Olson from Texas State University said.
Olson said a "once-in-many-lifetimes" event occurred on Jan. 4, 1912, when the moon and sun lined up in such a way that their gravitational pulls enhanced each other. At the same time, the moon's closest approach to earth that January was the closest in 1,400 years.
The high tide caused by the bizarre combination of astronomical events would have been enough to dislodge icebergs from Greenland in January 1912 and give them enough buoyancy to reach the shipping lanes by April, Olson said.
