Two astronomers from Texas State University have speculated that a rare “supermoon” may have been to blame for setting the iceberg in motion. This occurs when the Moon reaches its closest point to Earth at the same time as a full moon. January 4, 1912 saw a remarkable example, with the Moon coming closer to the Earth than at any point in the last 1,400 years.
The Moon and Sun were also aligned, causing an extremely strong tide. These events could have set the disaster in motion, with an extreme tide bringing a high number of icebergs in the Titanic’s path.
