00:00Let's talk about some deep stuff, shall we?
00:03A scientist spent 100 days below the surface of the Atlantic Ocean.
00:07Dr. Joseph Dutourie, or Dr. Deep Sea as he likes to call himself, was living underwater
00:12as part of Project Neptune 100.
00:16After 74 days of the mission, he officially set a new Guinness World Record for the longest
00:21time living in an underwater fixed habitat.
00:24But he didn't leave the experiment and stayed the plan 14 weeks.
00:28You can test yourself and stay in the exact same place where Dutourie lived.
00:32It's called Jules' Undersea Lodge after Jules Verne, author of 20,000 Leagues Under
00:38the Sea.
00:40The idea of Project Neptune 100 is to study how pressure affects humans, both physiologically
00:46and psychologically.
00:47Dr. Deep Sea, who is a biomedical engineer and associate professor at the University
00:52of South Florida, stayed so long underwater to see if increased pressure can help humans
00:58live longer and prevent health problems that come with old age.
01:02From day one of the mission, Dutourie actively shared what was going on on social media.
01:07He mentioned that another important goal for him was to inspire scientists from different
01:11generations to study life undersea.
01:14It was quite different from living on a submarine.
01:17Subs are sealed when they go underwater and have sea-level pressure, so people on it don't
01:22feel an enormous difference in pressure, even deep down.
01:25Dutourie's underwater home didn't have any solid hatches or airlocks between the
01:30ocean and the living space.
01:31It was like a glass of water turned upside down and pushed into a sink full of water.
01:37There was still a pocket of air at the top of the living space and a pool of water on
01:41the floor of one room coming from the ocean.
01:44So the air inside the lodge was squeezed by the ocean's weight and was about twice higher
01:49than on land.
01:51There isn't much research on what happens when we're exposed to hyperbaric pressure
01:55for a long time.
01:56There's only some data from submariners.
01:59Even after just 2 months under the sea, they had disturbed sleep patterns and problems
02:03with the levels of certain hormones that had to do with sleep.
02:07They also lost bone and muscle mass.
02:09Our bodies are built for sea-level conditions, but as pressure mounts, hydrogen sneaks into
02:15our bloodstream, causing chaos.
02:17Between 30 and 100 feet down, you might feel some euphoria, but dive deeper, and you'll
02:23feel like you've hit the bar too hard.
02:26Scientists think it has something to do with messed-up signals between neurons in our brains.
02:30Luckily for de Ture, he was only staying 30 feet deep, so it wasn't an issue.
02:36Still, he only got half the amount of sunlight we're used to on land, and not nearly the
02:40same amount of vitamin C.
02:43During the 100 days of the experiment, the scientist collected data, collaborated with
02:48other researchers, virtually taught a biomedical engineering course at his university, and
02:54reached out to thousands of students from different countries online.
02:57He stayed in the 2-bedroom apartment 30 feet below the surface of a lagoon in Key Largo,
03:02Florida.
03:03It's attached to the seabed by leg structures.
03:06There are three windows with a direct ocean view and some marine life outside.
03:10There's a command center that keeps oxygen, water, and power levels under control.
03:15An AC keeps the temperature comfortable, and a chef dives in to cook meals for whoever
03:20stays inside.
03:22When he was done with his mission, Dr. de Ture got back on the surface.
03:26His family and friends, the media, and many fans who were following his work online were
03:30waiting for him.
03:31He's now 55 years old, and he claims that living underwater has made him feel 10 years
03:37younger.
03:38The doctors who greeted him and the results of the tests they ran on him have demonstrated
03:42the anti-aging effect.
03:44Dr. Deepsea noticed some improvement in his sleep and metabolism.
03:48He also noted that his body had shrunk by a half an inch.
03:52He doesn't plan to stop his studies of how isolated environments affect humans.
03:56He's going to take a flight on a modified airliner where you can experience zero gravity
04:01multiple times.
04:02It's the next step to his dream of becoming a civilian astronaut and traveling into space
04:07by 2026.
04:10Meanwhile, Tim Yarrow in South Africa went even further and spent an impressive 10 days
04:16in the water, inside a tank at a shopping mall.
04:19He broke a world record, but his goal was just to find out what would happen to him.
04:24At the end of the experiment, his hands looked absolutely terrible.
04:29People who helped him fed Yarrow through a tube, and all his waste went out of the tank
04:33through a different tube.
04:34Good thing.
04:35Tim managed to survive the experiment, but he said he wouldn't like to do it again.
04:40Tim, a British biologist, explained that if he had stayed underwater longer, his skin
04:45would've broken down, and he would've gotten seriously ill.
04:49Luckily for Yarrow, his hands went back to normal after a while, and he didn't get
04:53any permanent injuries from this weird experience.
04:57If you're looking for more comfortable accommodations under the sea, you might want to stay at the
05:01world's first and most expensive underwater hotel in the Maldives.
05:07Guests of the Maraca Hotel wake up surrounded by the Indian Ocean, with bright coral reefs
05:12and exotic marine life.
05:14This luxurious suite was designed by top architects from New York and the Maldives.
05:19It's a two-story construction with an upper level that has spacious bedrooms, a sun deck,
05:24and an infinity pool.
05:26The lower level is submerged over 16 feet below sea level.
05:30Guests of the Maraca get the Royal Treatment, which includes private butler and chef services,
05:35complimentary jet skis, on-call massage and spa treatments, and cooking dishes with chefs.
05:41But before you start packing to the Maldives for your unique underwater experience, you
05:46must know it all costs almost $14,000 per night.
05:51One of the most exciting things humans have ever found underwater is the Yanaguni Monument
05:56off the coast of Japan.
05:58This structure is the closest we've ever been to finding Atlantis, and still one of the
06:03world's biggest mysteries.
06:05In 1986, a diver was looking for hammerhead sharks not far away from Yanagumi Island.
06:11He noticed a huge, unusual structure in the shallow water that resembled a pyramid with
06:16multiple steps or layers leading to the top with clear symmetrical edges, angles, and
06:22even steps.
06:23As it turned out later, it was made of shale and sandstone 20 million years old.
06:28No one knows how the construction got there in the first place, but one researcher is
06:32sure that humans built it 10,000 years ago and was part of the lost continent of Mu.
06:39This mythical continent, something like the Atlantis of the Pacific, was destroyed by
06:43a huge earthquake or hurricane and went under the sea.
06:47Its survivors moved across the Earth and found civilizations, including the ancient Egyptians
06:52and Maya.
06:53Academics often say this theory is nothing but a fairy tale, but the scientist who proposed
06:59it says only humans could have carved such straight lines, sharp corners, steps, avenues,
07:05and even statues that look like animals.
07:07Since earthquakes happen so often in Japan, the construction could have gone from the
07:11ground into the sea.
07:14The more widely accepted theory is that the monument is a work of nature.
07:18It explains the amazing symmetry with well-defined parallel bedding planes along which the layers
07:24easily separate.
07:25You can find similar 90-degree angles occurring in sandstone when erosion takes place.
07:31The area's naturally strong currents could also have shaped it.
07:34It's possible that over thousands of years, major tectonic activity could have fractured
07:39the sandstone into geometric patterns.
07:42During the Miocene period, tectonic activity collected vast amounts of sandstone in the
07:47area.
07:48Geologists think the monument could be part of a much larger underlying rock from this
07:52event.
07:53And earthquakes that often happen here have shaped the rocks into what they look like
07:58now.
07:59That's it for today!
