'Time reverse' technique reveals 800-year-old ghost ship mystery

One of Sweden's oldest ghost ships has appeared where it shouldn't have been, confusing scientists.

According to PHYS, the scientists used the technique of "reverse tree rings", roughly tracing the tree rings of the wooden slats that make up the ship, not to determine how old the tree is, but to determine how old the tree is. See what year they were cut down and used for shipbuilding.

Because if analyzed, scientists can see subtle signs of how that tree ring is created in climate conditions, subject to these natural influences. Compared with the known data about the environment at that time, we will know when the tree was cut down.

The results show that the oak slats were cut down between 1233 and 1240 AD, meaning the ship is almost 800 years old. It was a cogwheel train, a famous design in Europe at the time. Remains show the ship as intact as 20 meters long.

This wood has also been identified as oak in the forests of northwest Germany, far from the fishing village on the west coast of Sweden - the area near the island of Dyngö - where the ship was found.

According to researchers from the University of Gothenburg (Sweden), the reason the ship traveled so unusually far has three possibilities: it was attacked by pirates, burned by accident and sought help, or due to war. .

The cause of the shipwreck has not been fully determined, but the remains show that the ship was burned before forever becoming a ghost ship on the seabed, according to Acient Origins.
