‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence

What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept

If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker,” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey.
Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.”

In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered.

“Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look,” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek,’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.”

Broken spheres
Dyson died in 2020 before any of his spheres could be found — although they are just one of a dozen ideas that bear his name.

“As a young scientist, Dyson showed that three competing quantum theories were actually the same theory — he summarily ended the competition,” said William Press, the Leslie Surginer Professor of Computer Science and Integrative Biology at the University of Texas at Austin. He was not involved in the study. “Later, he applied his genius to areas of astronomy, cosmology, the extraterrestrial realm, and also the very real problem of nuclear proliferation here on planet Earth. At the time of his death, he was recognized as a provocative and creative thinker.”

George Dyson also attested to his father’s fascination and comprehensive reach across disciplines.

“Taking advantage of a short attention span and an aversion to bureaucracy, he contributed to five fields of mathematics and eleven fields of physics, as well as to theoretical biology, engineering, operations research, literature, and public affairs,” the younger Dyson said. “Many of his ideas were controversial, with one of his guiding principles being that ‘It is better to be wrong than to be vague.’”

The approach of the researchers behind the new study could offer a more fruitful path in the search for extraterrestrial intelligence, said Tomotsugu Goto, an associate professor of astronomy at the National Tsing Hua University in Taiwan. He also was not involved with the study.

“However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. “Authors argue that the debris disks around (dwarf stars) are rare, but the 7 candidate authors selected out of 5 million sources are also rare. Despite this, the seven candidates warrant further investigation with powerful telescopes for a more definitive evaluation.”

A job for the Webb space telescope

“We got 53 candidates for anomalies that cannot be well explained, but can’t say that all of them are Dyson sphere candidates, because that’s not what we are specifically looking for,” said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo’s model to see how many tie into it.

“You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere,” she added. “To do so you need to also rule out that it’s not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it’s a win-win.”

Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA’s James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.
If Dyson spheres really exist, what could they be used for? “If you picture ourselves having as much energy as the sun is providing every second, we could do unheard of things,” Suazo said. “We could do interstellar travel, maybe we could even move the entire solar system to our preferred location, if we wanted.”

But don’t hold your breath, because the technology and the raw materials required to build the hypothetical structures are far beyond humanity’s grasp.

“They are so big that everything we have on Earth would not be enough to build them,” Suazo added. “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”

That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare.

Why axolotls seem to be everywhere — except in the one lake they call home
kraken ссылка
Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory, he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls.

The amphibians’ fans tell Voss that they know the animals from the internet, or from caricatures or stuffed animals, exclaiming, “‘They’re so adorable, we love them,’” said Voss, a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.”

Take one look at an axolotl, and it’s easy to see why it’s so popular. With their wide eyes, upturned mouths and pastel pink coloring, axolotls look cheerful and vaguely Muppet-like.

They’ve skyrocketed in pop culture fame, in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery, exploitation of the natural world, and the work to rebuild humans’ connection with nature.

A scientific mystery
Axolotl is a word from Nahuatl, the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl, who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English, “ACK-suh-LAHT-uhl” is commonly used.
Axolotls are members of a class of animals called amphibians, which also includes frogs. Amphibians lay their jelly-like eggs in water, and the eggs hatch into water-dwelling larval states. (In frogs, these larvae are called tadpoles.)

Most amphibians, once they reach adulthood, are able to move to land. Since they breathe, in part, by absorbing oxygen through their moist skin, they tend to stay near water.

Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water.

“They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”
