"Cocaine of the sea" — the illegal fish trade of the Mexican cartel and Chinese mafia
"Sea of Shadows" is a documentary you can't afford to miss.
- "Sea of Shadows" tells the story of an illegal fish trade between the Mexican cartel and Chinese mafia.
- The fish bladders, bought for $5,000 from local fisherman, are sold in China for over $100,000 to make an unproven medicine.
- Director Richard Ladkani talks about the intensity and danger of making this film, as well as the hopeful ending.
In Traditional Chinese Medicine (TCM), the totoaba bladder is believed to cure arthritis. As with much of TCM, the claim is unproven and inevitably creates more harm than good. An entire ecosystem is on the verge of collapse thanks to the illegal bladder trade between the Mexican cartel and Chinese businessmen.
While the totoaba are rapidly declining in numbers—their only home is in the Sea of Cortez, the body of water that separates Baja California with mainland Mexico—the illegal fishing nets local fishermen use are killing everything else: turtles, sharks, and the focus of "Sea of Shadows," the vaquita. There are only believed to be 15 or so of these small porpoises left in existence.
As director and cinematographer, Richard Ladkani, told me earlier this week, there is hope as six vaquitas (including babies) were recently spotted. Since he filmed "Jane's Journey," an intimate portrait of English primatologist and anthropologist Jane Goodall, Ladkani has focused on environmentally relevant works. His last film, "The Ivory Game," helped make the ivory trade between Africa and China illegal. As you'll see while watching his incredible new National Geographic documentary, his film might help save an ecosystem "just five hours drive from Los Angeles."
But nothing is a given. At the end of our talk, Ladkani asked me to mention Earth League International and Sea Shepherd, the two organizations driving the activism in the Sea of Cortez. "Sea of Shadows" is heartbreaking and inspiring, frightening and ambitious. Most importantly, it's a reminder that people care about the fate of this planet and all the animals that reside here. In a time when most environmental news informs us that we're another step closer to a precipice, this film reminds us of the necessity of banding together and fighting for what's best for all of us.

Derek: Congratulations on "Sea of Shadows." And thank you for keeping me up all night.
Richard: I tell people to buckle up before the movie starts.
Derek: I would love to know how you became interested in this topic.
Richard: In general, I'm interested in films with impact and a mission behind them. That started with Jane Goodall, who I was lucky enough to follow around the world about 10 years ago while shooting a film called "Jane's Journey." She inspired me to look at the natural world in a different way and understand that our world is in peril and is really falling apart.
"The Ivory Game" was the first result of her inspiration. Then came "Sea of Shadows," which was brought to us by Leonardo DiCaprio, who was our executive producer on my previous film. He thought "The Ivory Game" was super successful on how we collaborated and how a movie can have such a huge impact, because it changed the law in China and made dealing with ivory illegal.
Two months after the movie came out, they invited us to China to screen the film at the Beijing Film Festival. That was such a big impact, that you can change the government's way of thinking about the world, even a Chinese government on top of that. We were thinking about the next story and Leonardo suggested something on the vaquita because he deeply cared about a small whale that nobody has ever heard about, including myself. He had just met with a Mexican president and was deeply involved in this rescue effort of scientists to save the vaquita.
Derek: While the film is focused on the totoaba and vaquita, you also mention that fishing them can collapse an entire ecosystem. Is that whole area going to be infertile if they continue this trade?
Richard: Absolutely. If the vaquita goes extinct, which we are trying everything in our power to impact, we'll feel we had a little part for not allowing that to happen. But if it happens, it will mean that the cartel is going to completely take over the area. The attention, the focus, the spotlight that it has right now is because of the vaquita; it is such a symbolic animal and it's been highly exposed. If the vaquita goes extinct, the NGOs will be removed from the area. They will move onto a new war somewhere, maybe in Peru or South Africa.
Then what will happen is the cartel is going to 100% take over the Sea of Cortez. All the fishermen are going to be pressured to go out for the totoaba. You've seen how they do it. They dropped thousands of gill nets, walls of death that kill everything just to get to that final totoaba. They will kill everything and it's all tossed away. All the sharks, the turtles, everything will disappear just because they're going for that totoaba.

Derek: An ecosystem might collapse half a world away because of a fish bladder that supposedly cures arthritis, with no scientific proof whatsoever. Did you do any research on TCM for the film?
Richard: Yes, of course. We even filmed in China for a month. The reason we didn't include that in the film was because we realized that there was no demand; it is already illegal to trade totoaba there. Every scientist we talked to said it's not proven Western science. They couldn't find any proof that it has any power at all. But then we realized that it would take a whole generation or a campaign to change the minds of the Chinese. The vaquita maybe has 12 months to live.
It will never be solved in China. There is nothing we can do in China that will stop this trade in time. In other cases, like with the elephants, it was 10 years to extinction. We had the time to go there. But in this case, it just didn't make any sense. There was a whole half-hour worth of dramatic events in China, but we took it all out because we wanted people to focus on where the solution is, which is in Mexico.
Derek: Speaking of dramatic events, I love how you focus both on the media aspect of the trade and the race against the cartel. There were some failures too; I'm glad you highlighted them. How did your crew emotionally deal with making this film?
Richard: It was like a roller coaster ride. The dramatic scenes that happened with the vaquita were unthinkable. I was very close with the scientists, with Cynthia Smith; we became friends and she really trusted us. By the end they gave us full access. Living through that traumatic scenes as the moments unfold was just beyond belief. It was really tough for us to be there. I tried to be as invisible as possible and stay out of their way.
At the same time, this film became more and more dangerous every week that we were on location. It was a big responsibility to keep the team safe and to keep going and pushing. Our production company provided a full security budget for us. We had very professional bodyguards that know what they're doing, people that we can trust who are not bought by the cartel or corrupt police. It was like a big military operation to get this film made without anybody getting shot or kidnapped.
Derek: There was the scene when you were at the beach and the fisherman had taken over the Navy vessel. It reminded me a little bit of "Restrepo," from the camera crew perspective: You're in the middle of a war, you're getting rocks thrown at you, and you're getting shot at. Even though you had bodyguards, there was a lot of personal danger.
Richard: It was the most dangerous moment of the entire production. It was also the worst case scenario. In all the planning that went into the film, we always said this is what we need to avoid—a flash mob of people trying to come at us from all sides. We were just trying to get out of it alive and keep everyone safe, but at the same time it was also the challenge of actually capturing that moment and everything that came with it and not stop shooting. Even though I was running for my life, I kept the camera rolling on my shoulder and made sure that that red light was on. If you stop shooting, then you may also lose that one opportunity to really get the audience to understand what these people are going through.
Riots break out in San Felipe as fishermen protest the arrests of totoaba poachers.
Derek: You might not have been worried about framing, but when you see a rock fly by three feet from your feet, you know exactly what's happening.
Richard: Of course. We were hiding behind cars and everything, so I knew what was happening. There was fear, but there was also control in the way of staying focused. What scared me the most was when shots started to appear. We were hearing gunfire, and I didn't know who was shooting at who because we weren't able to see. Did the cartel open fire on us? Is it the Navy shooting at them or in the air? I heard bullets ricocheting off walls around us; that meant that they are firing not in the air but actually at us.
There's stuff that is not in the film, when we got threatened by the cartel right after because they had exposed our identities. They had photographed us, then they followed us home. Then we got direct threats from Oscar Parra. Actually, he requested a meeting with me the following night and said I had to come alone. And I was like, "No, I don't think so."
Derek: I wouldn't have taken that meeting either. There's also a moment where the drone gets shot down. I've known about Sea Shepherd for a long time; they do amazing work. When you see the crew members, they look like a bunch of young kids, but they have to be pretty tough to do that job.
Richard: They are amazing. The average age on ship was 22 and that was just insane, but they're all fired up. They're all activists and wanted to sign up for this battle of the Sea of Cortez. They're very inspiring people. It was always great to be on the ship. I really admire them.
Derek: One of the stories in the film involves the Mexican Navy and how they go from giving you platitudes, then later you're riding along with the Navy. Was it the media pressure that made them change?
Richard: It was actually Carlos Loret de Mola who kept pressuring them: "Show me how you're fighting this war, how you want to win." We were lucky because we were following Carlos; we were sort of his team so they didn't question who we are. We had access to all the operations. But as you see, you think there's something off here: There's all this presence but somehow they're always in the wrong place at the wrong time. They even release the prisoners in the end.
It was after the riots that I confronted the Vice Admiral and asked him, "What the hell is going on? How can you not get on top of that situation?" That's when he told me to stop filming. Then he told me, "Richard, they know where my daughter goes to school, they know where we live, they know the name of my wife, and they will first come for my daughter and kidnap her. Then they will kill her, my wife, and then they will come from me. That's why I'm not getting in their way."
Derek: Do you have any updates since the film has been completed?
Richard: Yes, we're constantly in touch with everybody. Earth League International has put together a new mission to go back in and monitor the situation. Because the totoaba season is just beginning, the cartel is moving in. They have sent out Mexican and Chinese investigators to monitor the trafficking. The good news is that they're dispatching an additional 600 troops to the area and they have committed 14 warships to protect the vaquita refuge.
The president visited the region and started talking about the vaquitas, that they need to save them and offer solutions for all the fishermen. So we are upbeat. Also, six vaquitas have been spotted in early October; some of them are babies, which is fantastic news. It shows us that they're still there and it's not too late.
Inventions with revolutionary potential made by a mysterious aerospace engineer for the U.S. Navy come to light.
- U.S. Navy holds patents for enigmatic inventions by aerospace engineer Dr. Salvatore Pais.
- Pais came up with technology that can "engineer" reality, devising an ultrafast craft, a fusion reactor, and more.
- While mostly theoretical at this point, the inventions could transform energy, space, and military sectors.
The U.S. Navy controls patents for some futuristic and outlandish technologies, some of which, dubbed "the UFO patents," came to life recently. Of particular note are inventions by the somewhat mysterious Dr. Salvatore Cezar Pais, whose tech claims to be able to "engineer reality." His slate of highly-ambitious, borderline sci-fi designs meant for use by the U.S. government range from gravitational wave generators and compact fusion reactors to next-gen hybrid aerospace-underwater crafts with revolutionary propulsion systems, and beyond.
Of course, the existence of patents does not mean these technologies have actually been created, but there is evidence that some demonstrations of operability have been successfully carried out. As investigated and reported by The War Zone, a possible reason why some of the patents may have been taken on by the Navy is that the Chinese military may also be developing similar advanced gadgets.
Among Dr. Pais's patents are designs, approved in 2018, for an aerospace-underwater craft of incredible speed and maneuverability. This cone-shaped vehicle can potentially fly just as well anywhere it may be, whether air, water or space, without leaving any heat signatures. It can achieve this by creating a quantum vacuum around itself with a very dense polarized energy field. This vacuum would allow it to repel any molecule the craft comes in contact with, no matter the medium. Manipulating "quantum field fluctuations in the local vacuum energy state," would help reduce the craft's inertia. The polarized vacuum would dramatically decrease any elemental resistance and lead to "extreme speeds," claims the paper.
Not only that, if the vacuum-creating technology can be engineered, we'd also be able to "engineer the fabric of our reality at the most fundamental level," states the patent. This would lead to major advancements in aerospace propulsion and generating power. Not to mention other reality-changing outcomes that come to mind.
Among Pais's other patents are inventions that stem from similar thinking, outlining pieces of technology necessary to make his creations come to fruition. His paper presented in 2019, titled "Room Temperature Superconducting System for Use on a Hybrid Aerospace Undersea Craft," proposes a system that can achieve superconductivity at room temperatures. This would become "a highly disruptive technology, capable of a total paradigm change in Science and Technology," conveys Pais.

Another invention devised by Pais is an electromagnetic field generator that could generate "an impenetrable defensive shield to sea and land as well as space-based military and civilian assets." This shield could protect from threats like anti-ship ballistic missiles, cruise missiles that evade radar, coronal mass ejections, military satellites, and even asteroids.
Dr. Pais's ideas center around the phenomenon he dubbed "The Pais Effect". He referred to it in his writings as the "controlled motion of electrically charged matter (from solid to plasma) via accelerated spin and/or accelerated vibration under rapid (yet smooth) acceleration-deceleration-acceleration transients." In less jargon-heavy terms, Pais claims to have figured out how to spin electromagnetic fields in order to contain a fusion reaction – an accomplishment that would lead to a tremendous change in power consumption and an abundance of energy.
According to his bio in a recently published paper on a new Plasma Compression Fusion Device, which could transform energy production, Dr. Pais is a mechanical and aerospace engineer working at the Naval Air Warfare Center Aircraft Division (NAWCAD), which is headquartered in Patuxent River, Maryland. Holding a Ph.D. from Case Western Reserve University in Cleveland, Ohio, Pais was a NASA Research Fellow and worked with Northrop Grumman Aerospace Systems. His current Department of Defense work involves his "advanced knowledge of theory, analysis, and modern experimental and computational methods in aerodynamics, along with an understanding of air-vehicle and missile design, especially in the domain of hypersonic power plant and vehicle design." He also has expert knowledge of electrooptics, emerging quantum technologies (laser power generation in particular), high-energy electromagnetic field generation, and the "breakthrough field of room temperature superconductivity, as related to advanced field propulsion."
Suffice it to say, with such a list of research credentials that would make Nikola Tesla proud, Dr. Pais seems well-positioned to carry out groundbreaking work.

The patents won't necessarily lead to these technologies ever seeing the light of day. The research has its share of detractors and nonbelievers among other scientists, who think the amount of energy required for the fields described by Pais and his ideas on electromagnetic propulsions are well beyond the scope of current tech and are nearly impossible. Yet investigators at The War Zone found comments from Navy officials that indicate the inventions are being looked at seriously enough, and some tests are taking place.

These Roman Emperors were infamous for their debauchery and cruelty.
- Roman Emperors were known for their excesses and violent behavior.
- From Caligula to Elagabalus, the emperors exercised total power in the service of their often-strange desires.
- Most of these emperors met violent ends themselves.
We rightfully complain about many of our politicians and leaders today, but historically speaking, humanity has seen much worse. Arguably no set of rulers has been as debauched, ingenious in their cruelty, and prone to excess as the Roman Emperors.
While this list is certainly not exhaustive, here are seven Roman rulers who were perhaps the worst of the worst in what was one of the largest empires that ever existed, lasting for over a thousand years.
Officially known as Gaius (Gaius Caesar Augustus Germanicus), Caligula was the third Roman Emperor, ruling from 37 to 41 AD. He acquired the nickname "Caligula" (meaning "little [soldier's] boot") from his father's soldiers during a campaign.
While recognized for some positive measures in the early days of his rule, he became famous throughout the ages as an absolutely insane emperor, who killed anyone when it pleased him, spent exorbitantly, was obsessed with perverse sex, and proclaimed himself to be a living god.

Among his litany of misdeeds, according to the accounts of Caligula's contemporaries Philo of Alexandria and Seneca the Younger, he slept with whomever he wanted, brazenly taking other men's wives (even on their wedding nights) and publicly talking about it.
He also had an insatiable blood thirst, killing for mere amusement. Once, as reports historian Suetonius, when the bridge across the sea at Puteoli was being blessed, he had a number of spectators who were there to inspect it thrown off into the water. When some tried to cling to the ships' rudders, Caligula had them dislodged with hooks and oars so they would drown. On another occasion, he got so bored that he had his guards throw a whole section of the audience into the arena during the intermission so they would be eaten by wild beasts. He also allegedly executed two consuls who forgot his birthday.
Suetonius relayed further atrocities of the mad emperor's character, writing that Caligula "frequently had trials by torture held in his presence while he was eating or otherwise enjoying himself; and kept an expert headsman in readiness to decapitate the prisoners brought in from gaol." One particular form of torture associated with Caligula involved having people sawed in half.
He caused mass starvation and purposefully wasted money and resources, like making his troops stage fake battles just for theater. If that wasn't enough, he turned his palace into a brothel and was accused of incest with his sisters, Agrippina the Younger, Drusilla, and Livilla, whom he also prostituted to other men. Perhaps most famously, he was planning to appoint his favorite horse Incitatus a consul and went as far as making the horse into a priest.
In early 41 AD, Caligula was assassinated by a conspiracy of Praetorian Guard officers, senators, and other members of the court.
Fully named Nero Claudius Caesar, Nero ruled from 54 to 68 AD and was arguably an even worse madman than his uncle Caligula. He had his step-brother Britannicus killed, his wife Octavia executed, and his mother Agrippina stabbed and murdered. He personally kicked to death his lover Poppeaea while she was pregnant with his child — a horrific action the Roman historian Tacitus depicted as "a casual outburst of rage."
He spent exorbitantly and built a 100-foot-tall bronze statue of himself called the Colossus Neronis.
He is also remembered for being strangely obsessed with music. He sang and played the lyre, although it's not likely he really fiddled as Rome burned in what is a popular myth about this crazed tyrant. As misplaced retribution for the fire which burned down a sizable portion of Rome in the year 64, he executed scores of early Christians, some of them outfitted in animal skins and brutalized by dogs, with others burned at the stake.
He died by suicide.

Like some of his counterparts, Commodus (a.k.a. Lucius Aelius Aurelius Commodus) thought he was a god — in his case, a reincarnation of the Greek demigod Hercules. Ruling from 176 to 192 AD, he was also known for his debauched ways and strange stunts that seemed designed to affirm his divine status. Numerous statues around the empire showed him as Hercules, a warrior who fought both men and beasts. He fought hundreds of exotic animals in an arena like a gladiator, confusing and terrifying his subjects. Once, he killed 100 lions in a single day.

The burning desire to kill living creatures as a gladiator for the New Year's Day celebrations in 193 AD brought about his demise. After Commodus shot hundreds of animals with arrows and javelins every morning as part of the Plebeian Games leading up to New Year's, his fitness coach (aptly named Narcissus), choked the emperor to death in his bath.
Officially named Marcus Aurelius Antoninus II, Elagabalus's nickname comes from his priesthood in the cult of the Syrian god Elagabal. Ruling as emperor from 218 to 222 AD, he was so devoted to the cult, which he tried to spread in Rome, that he had himself circumcised to prove his dedication. He further offended the religious sensitivities of his compatriots by essentially replacing the main Roman god Jupiter with Elagabal as the chief deity. In another nod to his convictions, he installed on Palatine Hill a cone-like fetish made of black stone as a symbol of the Syrian sun god Sol Invictus Elagabalus.
His sexual proclivities were also not well received at the time. He was likely transgender (wearing makeup and wigs), had five marriages, and was quite open about his male lovers. According to the Roman historian (and the emperor's contemporary) Cassius Dio, Elagabalus prostituted himself in brothels and taverns and was one of the first historical figures on record to be looking for sex reassignment surgery.
He was eventually murdered in 222 in an assassination plot engineered by his own grandmother Julia Maesa.
Emperor for just eight months, from April 19th to December 20th of the year 69 AD, Vitellius made some key administrative contributions to the empire but is ultimately remembered as a cruel glutton. He was described by Suetonius as overly fond of eating and drinking, to the point where he would eat at banquets four times a day while sending out the Roman navy to get him rare foods. He also had little social grace, inviting himself over to the houses of different noblemen to eat at their banquets, too.

He was also quite vicious and reportedly either had his own mother starved to death or approved a poison with which she committed suicide.
Vitellius was ultimately murdered in brutal fashion by supporters of the rival emperor Vespasian, who dragged him through Rome's streets, then likely beheaded him and threw his body into the Tiber river. "Yet I was once your emperor," were supposedly his last words, wrote historian Cassius Dio.
Marcus Aurelius Antoninus I ruled Rome from 211 to 217 AD on his own (while previously co-ruling with his father Septimius Severus from 198). "Caracalla"' was his nickname, referencing a hooded coat from Gaul that he brought into Roman fashion.
He started off his rise to individual power by murdering his younger brother Geta, who was named co-heir by their father. Caracalla's bloodthirsty tyranny didn't stop there. He wiped out Geta's supporters and was known to execute any opponents to his or Roman rule. For instance, he slaughtered up to 20,000 citizens of Alexandria after a local theatrical satire dared to mock him.

One of the positive outcomes of his rule was the Edict of Caracalla, which gave Roman citizenship to all free men in the empire. He was also known for building gigantic baths.
Like others on this list, Caracalla met a brutal end, being assassinated by army officers, including the Praetorian prefect Opellius Macrinus, who installed himself as the next emperor.
As the second emperor, Tiberius (ruling from 42 BC to 16 AD) is known for a number of accomplishments, especially his military exploits. He was one of the Roman Empire's most successful generals, conquering Pannonia, Dalmatia, Raetia, and parts of Germania.
He was also remembered by his contemporaries as a rather sullen, perverse, and angry man. In the chapter on his life from The Lives of the Twelve Caesars by the historian Suetonius, Tiberius is said to have been disliked from an early age for his personality by even his family. Suetonius wrote that his mother Antonia often called him "an abortion of a man, that had been only begun, but never finished, by nature."
"Orgy of the Times of Tiberius on Capri".Painting by Henryk Siemiradzki. 1881.
Suetonius also paints a damning picture of Tiberius after he retreated from public life to the island of Capri. His years on the island would put Jeffrey Epstein to shame. A horrendous pedophile, Tiberius had a reputation for "depravities that one can hardly bear to tell or be told, let alone believe," Suetonius wrote, describing how "in Capri's woods and groves he arranged a number of nooks of venery where boys and girls got up as Pans and nymphs solicited outside bowers and grottoes: people openly called this 'the old goat's garden,' punning on the island's name."
There's much, much more — far too salacious and, frankly, disgusting to repeat here. For the intrepid or morbidly curious reader, here's a link for more information.
After he died, Tiberius was fittingly succeeded in emperorship by his grandnephew and adopted grandson Caligula.
New studies stretch the boundaries of physics, achieving quantum entanglement in larger systems.
- New experiments with vibrating drums push the boundaries of quantum mechanics.
- Two teams of physicists create quantum entanglement in larger systems.
- Critics question whether the study gets around the famous Heisenberg uncertainty principle.
Recently published research pushes the boundaries of key concepts in quantum mechanics. Studies from two different teams used tiny drums to show that quantum entanglement, an effect generally linked to subatomic particles, can also be applied to much larger macroscopic systems. One of the teams also claims to have found a way to evade the Heisenberg uncertainty principle.
One question that the scientists were hoping to answer pertained to whether larger systems can exhibit quantum entanglement in the same way as microscopic ones. Quantum mechanics proposes that two objects can become "entangled," whereby the properties of one object, such as position or velocity, can become connected to those of the other.
An experiment performed at the U.S. National Institute of Standards and Technology in Boulder, Colorado, led by physicist Shlomi Kotler and his colleagues, showed that a pair of vibrating aluminum membranes, each about 10 micrometers long, can be made to vibrate in sync, in such a way that they can be described to be quantum entangled. Kotler's team amplified the signal from their devices to "see" the entanglement much more clearly. Measuring their position and velocities returned the same numbers, indicating that they were indeed entangled.

Evading the Heisenberg uncertainty principle?
Another experiment with quantum drums — each one-fifth the width of a human hair — by a team led by Prof. Mika Sillanpää at Aalto University in Finland, attempted to find what happens in the area between quantum and non-quantum behavior. Like the other researchers, they also achieved quantum entanglement for larger objects, but they also made a fascinating inquiry into getting around the Heisenberg uncertainty principle.
The team's theoretical model was developed by Dr. Matt Woolley of the University of New South Wales. Photons in the microwave frequency were employed to create a synchronized vibrating pattern as well as to gauge the positions of the drums. The scientists managed to make the drums vibrate in opposite phases to each other, achieving "collective quantum motion."
The study's lead author, Dr. Laure Mercier de Lepinay, said: "In this situation, the quantum uncertainty of the drums' motion is canceled if the two drums are treated as one quantum-mechanical entity."
This effect allowed the team to measure both the positions and the momentum of the virtual drumheads at the same time. "One of the drums responds to all the forces of the other drum in the opposing way, kind of with a negative mass," Sillanpää explained.
Theoretically, this should not be possible under the Heisenberg uncertainty principle, one of the most well-known tenets of quantum mechanics. Proposed in the 1920s by Werner Heisenberg, the principle generally says that when dealing with the quantum world, where particles also act like waves, there's an inherent uncertainty in measuring both the position and the momentum of a particle at the same time. The more precisely you measure one variable, the more uncertainty in the measurement of the other. In other words, it is not possible to simultaneously pinpoint the exact values of the particle's position and momentum.

Big Think contributor astrophysicist Adam Frank, known for the 13.8 podcast, called this "a really fascinating paper as it shows that it's possible to make larger entangled systems which behave like a single quantum object. But because we're looking at a single quantum object, the measurement doesn't really seem to me to be 'getting around' the uncertainty principle, as we know that in entangled systems an observation of one part constrains the behavior of other parts."
Ethan Siegel, also an astrophysicist, commented, "The main achievement of this latest work is that they have created a macroscopic system where two components are successfully quantum mechanically entangled across large length scales and with large masses. But there is no fundamental evasion of the Heisenberg uncertainty principle here; each individual component is exactly as uncertain as the rules of quantum physics predicts. While it's important to explore the relationship between quantum entanglement and the different components of the systems, including what happens when you treat both components together as a single system, nothing that's been demonstrated in this research negates Heisenberg's most important contribution to physics."The papers, published in the journal Science, could help create new generations of ultra-sensitive measuring devices and quantum computers.
