The U.S. Coast Guard announced on the evening of June 22 that a search robot had found "a number of Titan submersible fragments" in the search area near the sinking site of the Titanic.
Authorities later confirmed that five men were killed in an underwater explosion inside the Titan submersible.
During a search on June 21, a Canadian P8 Poseidon aircraft picked up sounds near the Titan submersible that went missing last weekend, the Daily Mail reported.
This raised hopes that people inside Titan were sending out a distress signal. Unmanned diving equipment has been deployed in the area to detect some of these sounds.
Based on this finding, it is speculated that the sounds came from five people inside the Tin Tan submersible. However, five passengers who were missing from the Titan submersible during its visit to the wreck of the Titanic have been confirmed dead as the US Coast Guard announced that the Titan had exploded.
In fact, according to experts, they were killed before they even realized what was happening.
Much evidence suggests that if they were still alive, they would not have been strong enough to hit the hull of the ship, making a loud sound that traveled to the surface.
According to experts, many theories have been put forward that the sounds may come from search engines in the area, marine life such as whales, or even sounds from the ocean.
Dr Jamie Pringle of Keele University in the UK thinks these are man-made sounds because the ocean is a very noisy place with many ships including submarines, fishing boats... active in motion.
He thinks it's also unlikely that the sound of the Titanic wreck echoes on the surface at this depth. However, the sound was heard every 30 minutes, suggesting it was man-made. He also denied that the sound was not the propeller of a continuously running train
Matthew Shank, founder of Marsar International, a maritime search and rescue group, also believes the sound is man-made. He added that it could be ships, equipment, or heavy machinery in the area...
Contrary to the above two views, Professor Stefan B. Williams believes that these sounds may be made by whales. He explained that the region of the North Atlantic where the Titan submersible went missing is home to many species of whales.
On the other hand, Professor Jeff Carson of Syracuse University in the United States speculated that these sounds may come from the wreck of the Titan floating somewhere on the ocean floor.
