Stories of strange objects moving in the deep sea always make us confused and curious. These objects can move at speeds of up to 150 knots, and can dive to depths of more than 6,000 meters without any problems. These strange objects have the ability to dive incredibly deep, even deeper than the most modern submarines. This is an extremely surprising ability, because it takes ordinary submarines many hours to dive to such depths, due to complex technical processes. However, these strange objects can dive deep and surface in the blink of an eye, leaving us confused by their extraordinary ability to move.

Reports of these strange objects are not only in a few areas, but have been recorded in many different seas around the world, such as the Mediterranean, near Australia and New Zealand. Maritime records also show that similar phenomena have been recorded for centuries, with notes in the diaries and notebooks of experienced sailors. The issues surrounding these strange objects make us wonder. Are they man-made submarines, or entities beyond our understanding? And if they are not man-made, then what are they? These questions remain unanswered, making us even more curious and wanting to learn more about these mysteries.

Not only are there strange objects moving under the sea, but there are also stories about ghost ships, ships that disappeared and then mysteriously reappeared. These stories always make us shiver and curious to know the truth. There are many mysterious events related to ghost ships recorded in history. For example, the Mary Celeste, an American cargo ship found in 1872 in the Atlantic Ocean, with all its crew and passengers mysteriously missing. Or the FS Cyclops, an American troop ship that disappeared in 1918 with more than 300 crew members. Such events always make us wonder: What did those crew members experience before they disappeared.

In addition to mysterious historical events, there are many folk tales about ghost ships. These stories are often passed down through generations, and are considered legends of the ocean. For example, the story of the Flying Dutchman, a ghost ship cursed to sail forever at sea, or the story of the Octavius, a ship that disappeared in 1762 and was later found in 1775 with all its crew dead. Such stories always make us shiver and wonder if they could be true. Although ghost ship stories always make us curious, there are also many scientific explanations for these phenomena. For example, the phenomenon of "Fata Morgana", in which distant objects can be distorted, deformed and even appear in the air, or the phenomenon of "Ghost Ships" due to the reflection of light. However, these explanations still cannot explain all the mysterious stories about ghost ships.

There are not only strange objects and stories about ghost ships, but also mysterious noises coming from the deep sea. These noises always make us curious and worried about the unknown things happening at the bottom of the sea. Mysterious noises at the bottom of the sea have been recorded in many historical records. For example, explorers and sailors from centuries ago have reported strange noises coming from the bottom of the sea. These noises have been described as “loud booms” or “breathing sounds” and have always left listeners feeling uneasy and shivering. These mysterious noises have attracted the attention of many scientists and people interested in the mysteries of the ocean. There are many hypotheses about the origin of these noises, such as geological activities, the activities of marine creatures, or even submarines or strange objects moving on the seabed. However, until now, there has not been a unified and satisfactory explanation for the origin of these noises. Mysterious noises under the sea not only make us curious, but also raise concerns about possible impacts. For example, these noises can affect maritime activities and disturb marine creatures. In addition, the origin of these noises has not been clearly identified, so we need to continue to research and learn about this issue to ensure the safety of humans and the marine environment.

In addition to strange objects and mysterious noises, the ocean also contains many mysterious and scary creatures that we have not yet discovered. These creatures have always been the inspiration for mysterious and scary stories about the ocean. One of the most mysterious and scary creatures under the sea is the giant creatures. For example, the giant octopus, one of the largest animals on Earth, measuring up to 43 feet (about 13 meters) and can defeat whales. Or the giant squid, a mysterious animal that is said to be up to 43 feet in size. These creatures always make us feel in awe and wonder if they can have the terrible abilities as in folk tales.

In addition to giant creatures, the ocean also hides many other strange and mysterious creatures. For example, the old man fish, a strange fish with a wrinkled face like an old man, or the devil fish, a fish with a strange and scary shape. These creatures always make us amazed and wonder if they can hide undiscovered mysteries. As with other ocean-related issues, mysterious creatures under the sea have also become the inspiration for many folk tales. For example, the story of the sea monster, a giant and terrifying creature described as being able to swallow entire ships, or the story of the Loch Ness monster, a mysterious creature that lives in Loch Ness in Scotland. Such stories always make us curious and feel scared about the undiscovered things in the deep sea.
