[Có thể bạn chưa biết] The truth about ghost ships


The story of 1884, on a misty morning, the British ship "Rumney" hit the French ship called "Frigorifique." When the water spilled into the deck, the French sailor had to leave the Frigorifique. and go to "Rumney".




But then, while heading towards the harbor, something suddenly appeared from the mist, which was the abandoned ship "Frigorifique". The unmanned ship headed straight for Rumney, too close to react, a fatal crash that sank the "Rumney" ship. When the sailors tried to climb onto the lifeboat, the ship "Frigorifique" seemed to be very gloating for successfully avenging those who abandoned her, it silently disappeared in the fog without leaving a trace. .

Listening to the story is really sly, right? But in fact, when leaving the ship, the French sailors still left the engine running and the "Frigorifique" ship went a circle before crashing into the "Rumney" and then also sank under the sea. However, it still became one of many stories about ghost ships, unmanned ships floating in the sea.

Although these stories are inspirational for cult songs like "Pirates of the Caribbean", in fact, unmanned ships are not derived from ghosts, but are only products of phenomena. Physical only.

Ship Mary Celeste

One of the most famous ghost ships in the world was discovered floating in the Atlantic Ocean in 1872 and without a driver, all life buoys disappeared, in the deck with sea water and cargo lots. intact and the captain's abrupt end diary has sparked many spooky rumors.

But the culprit is really two scientific phenomena: the repulsion of water and hydrodynamics.

The following is the principle of operation of the repulsion of water: An object placed on a liquid will displace a portion of that liquid, the liquid will create a repulsion as the floating object equal to the weight of the liquid being take place, if the thrust is greater than the weight of the object, the floating object, in contrast, will sink. This phenomenon is called Archimedes Thrust.

Non-condensed objects such as wood, icebergs and steam boats will always float, which is because thrust is always greater than the gravity of the object. But for objects or boats made of materials such as steel – denser material than water – these objects must occupy a larger volume of water than their weight.

Normally, the amount of water contained in a hull will increase the weight of the ship and cause it to sink – it is also the fear of the sailor "Mary Celeste" when they abandon it.

But the sailors did not think about another concept, hydrodynamics – the water stopped flowing into the vessel at equilibrium. When the water was equal to the hull, it turned out that the water weight was not enough to make the ship sink and "Mary Celeste" was found a few days later while no one in the ill-fated water crew survived.

Ship A. Ernest Mills

A more strange story is about the ship "A. Ernest Mills," a ship transporting salt, witnessed by the crew who sank to the bottom of the sea after a collision. Yet four days later, the boat was found floating on the sea surface.

The explanation for this mystery lies in the salt shipment of the boat. The weight of water spilling into the hull caused it to sink, but when the salt was dissolved in the water, the weight decreased, making the gravity smaller than the thrust and the boat floated up again.

But how to explain the phenomenon of ghost ship legends appearing at places far away from each other?

The answer is because of ocean currents, they are like invisible rivers that flow through the ocean. Factors such as temperature, salinity, wind, gravity and Coriolis effect from Earth's movement create a complex motion system of ocean currents.

This happens both on the surface and on the bottom of the sea. The sailors always knew about the ocean currents, but recently the models of these currents were only known. Thanks to the determination of the direction and speed of ocean currents, scientists can search for abandoned ships more easily.

The derelict ships are not driven by ghost sailors or control curse but they travel on the ocean with intangible scientific elements, it will be extremely interesting to learn deeply about them.
