Nothing escapes the yawning chasm of a black hole – not matter, sound nor even light.
Normally confined to the reaches of space, black holes and their seemingly insatiable appetites for everything, have fascinated — and enlightened — scientists for years.
Now, they may not have to look so far to study them.
Researchers at Switzerland’s ETH Zurich and the University of Miami say black holes are among us — at least, massive eddies in the southern Atlantic Ocean bear their telltale signatures.
What a black hole is to light, an ocean eddy, scientists suggest, is to water. Dubbedmaelstroms, they’re bigger than cities, winding up billions of tonnes of ocean water so tightly, nothing escapes them.
And scientists are discovering more every day.
In a paper published earlier this month in the Journal of Fluid Mechanics, George Haller, a professor at ETH Zurich and Francisco Beron-Vera of the University of Miami claim they can track and define these engorged eddies — a feat that has, until now, proven elusive.
The ocean’s natural turbulence has thwarted previous attempts to demarcate these islands of intensity. But, by studying satellite imagery, Haller and Baron-Vera were able to identify seven black-hole types in a group of eddies, called Agulhas Rings, that regularly appear off the tip of Africa.
Maelstroms have the same mathematical properties as black holes.
Now, consider a real black hole. As explained in Science World Report, there’s a point where light being sucked into a black hole stops spiraling — bending instead, before returning to its usual position. The result is a circular orbit.
The dramatic effect of these closed light orbits, dubbed a ‘photon sphere’ by Albert Einstein, finds a parallel in these ocean vortexes, according to scientists. Essentially, the maelstrom whips up its own closed barriers, pressing whatever was sucked inside so tightly that not even a drop of these fluid particles can escape.
In fact, researchers have found eddies bearing the same bodies of water without leaking a drop for nearly a year.
”Mathematicians have been trying to understand such peculiarly coherent vortices in turbulent flows for a very long time,” George Haller explained in a statement.
That stunning sense of stability makes maelstroms something of a transportation device. Everything from the tiniest organisms to waste or oil to higher-temperature water is transported perfectly intact throughout the oceans before the maelstroms eventually lose their charge.
As the study authors note, they “create moving oases for the marine food chain or even impact climate change through their long-range transport of salinity and temperature.”
By casting light on these black holes (if you will excuse the pun), researchers could unravel the mystery of how pollution spreads throughout the environment, ETH Life reports. These maelstroms may also help scientists develops ways to at least slow down the melting of global sea ice.

Indo siren destroyed by fire
Indo Siren, a vessel from the Master Liveaboards Fleet, has been destroyed by a fire this morning. Thankfully, all guests and crew members are safe.
Master Liveaboards have released the following statement:
During our current cruise in Raja Ampat, on the morning of 30th November, a fire broke
out on Indo Siren. At the current time we are still assessing the events around the incident,
and will be working with authorities, so cannot currently comment further.
All guests and staff departed the boat, without further incident. They are now with our
ground crew who have organised accommodations while we assist with all their other
needs going forwards.
We are currently evaluating the issues created by the fire on upcoming trips. Guests who
are likely to be affected by enforced cancellations or changes will be contacted in due time
when plans are finalised.
We are incredibly grateful that this incident was not more serious and that everyone who
was onboard, both crew and guests, are safe and well.
The healing powers of adaptive diving
PADI highlights how scuba diving helps enrich and heal lives
This International Disabilities Day (3rd December) PADI is reminding the world of the healing aspects that the ocean (or any body of water) can provide and how important it is for helping those with physical or mental challenges improve their wellbeing. From simply being within close proximity of it or diving beneath the salty surface for an underwater adventure, the ocean has the power to heal.
Regardless of your age, ability, or even limitations, the ocean can benefit us physically, emotionally and even spiritually. This is why PADI is on a mission to make those benefits accessible to all, with their Adaptive Techniques Diving Course in the hope that all of humanity can experience the full transformational power of the ocean.
While many are more familiar with traditional therapies, diving, mermaiding or freediving, has changed the lives of those around the world by connecting with the water and enabled them to conquer mental or physical perceived limitations.
The PADI Adaptive Techniques Specialty course is unique in that it’s a pro-level specialty designed to educate and empower PADI Professionals who wish to make scuba and freediver training more accessible.
Through classroom, confined water and open water workshops, dive professionals further cultivate their ability to be student-centered and prescriptive in approach when adapting techniques to meet diver needs. This hands-on training increases awareness of differing abilities and explores adaptive teaching techniques to apply when training divers with physical and mental challenges. PADI Pros learn to adapt course content to accommodate virtually any student diver.
PADI Members Helping those with Disabilities
This International Disabilities Day PADI highlights a shining example of a member who is championing teaching those with disabilities how to dive.
DiveHeart Empowers Individuals Worldwide Through Adaptive Scuba Programmes
DiveHeart, a PADI Dive Centre founded by PADI Scuba Instructor Jim Elliott in 2001, continues to revolutionise the world of adaptive scuba. Using zero gravity and adaptive scuba, DiveHeart aims to instil confidence, foster independence, and elevate self-esteem among individuals facing physical and cognitive challenges.
DiveHeart has established Adaptive Scuba programmes across North America and the Caribbean and reaches global destinations including Malaysia, Australia, China, Israel, and the UK. Through a combination of donations, grants, and strategic partnerships, DiveHeart ensures inclusivity by providing services to children, veterans, individuals with ALS, autism, and others, irrespective of their abilities or financial means.
A significant milestone in DiveHeart’s journey was the hosting of the inaugural Adaptive Scuba Symposium in 2009, held at the prestigious Our World Underwater event in the Midwest. This pioneering symposium attracted a diverse array of experts, including researchers, physicians, professors, therapists, adaptive dive professionals, and participants from across the globe. The event delved into the current state and the future of adaptive scuba, scuba therapy, the adaptive scuba market, the latest in adaptive scuba training techniques and the latest in scuba therapy research.
At the forefront of adaptive scuba initiatives, DiveHeart offers specialised training courses for certified scuba divers to become adaptive dive buddies. Every diver with a disability is paired with two dive buddies to form a cohesive dive team, ensuring a safe and empowering experience.

People Who Have Healed from Diving
For people with disabilities—whether they use a wheelchair, have a sight impairment or a neurological condition like cerebral palsy—scuba diving can be a fun activity that offers freedom and mobility in the weightlessness of the water. PADI’s Adaptive Support Diver specialty is a course designed to teach friends and family adaptive techniques for diving with a buddy who has a disability. Many students take the course to support a particular person in their life, and the instructor can work with them on the specific skills they require.
Ryan Chen: Diving to Heal the Mind, Body and Spirit
Ryan is a PADI Open Water Scuba Diver who was in a tragic accident as a teenager that left him paralysed. He found healing and clarity through scuba diving with his dive buddy Kent Yoshimura – so much so that during one scuba diving trip he and Kent ended up creating their current company Neuro Gum – a collection of functional gum and mints that help you get energised, calm or focused that has now led him to be named on Forbes 30 under 30.
“Scuba diving was one of the ways I learned that I can do anything, I just have to do it differently,” Chen says, “Scuba diving is one of those things that can change your whole framework. There’s no cooler feeling than taking that first breath underwater. All of a sudden you have this superpower, to breathe underwater and explore.”
Scuba diving continues to be his physical and mental therapy he continually seeks out amidst his busy entrepreneurial life. Now, with Neuro a national success and leading wellness brand in the United States, Chen has kept up his diving, and remained close to PADI as an organisation. Neuro even has a collaboration with PADI’s coral reef restoration project coming up—a special pack of Neuro, with proceeds going to PADI’s non-profit foundation.
