Answer: Why on earth did Titanic hit an iceberg?

Tim Martin, a British historian, said that the crew of Titanic didn't notice the huge iceberg because of the abnormal reflection of light on the sea surface, which made the iceberg "invisible". When the ship reached the iceberg, it was too late to escape.

Extended data

Martin from Wiltshire, England, studied the weather map a century ago and the logbooks of other ships sailing in the North Atlantic when the Titanic sank, and found that the cold air brought by the Labrador cold current and the warm air brought by the Gulf Stream met just as the Titanic passed by, resulting in high pressure.

The British Daily Mail quoted him as saying on 2 1: "19 12 A weather map of the North Atlantic in April showed that when the Titanic sank, its air pressure was 1035 millibar (the standard pressure at sea level was10/kloc-)

The intersection of cold and warm air makes the light reflection abnormal and "obscures" the huge iceberg. Before hitting an iceberg, the Titanic ran at full speed for 20 minutes. Usually, the lookout on the ship should be able to see the iceberg.

Due to the abnormal light reflection, Titanic is extremely small in the eyes of the crew of "California", and the distress signal sent by Morse signal lamp on board is like a looming mast under the starry sky or an ordinary light on the deck. So Californians failed to rescue the Titanic in time.
