  Ukrainian President Volodymyr Zelensky’s visit to the White House on Thursday could be his final chance to convince a receptive American president of his country’s war aims.

  The precise details of the “victory plan” Zelensky plans to present in separate meetings to President Joe Biden and Vice President Kamala Harris are unknown, having been closely held until they are presented to the American leaders.
  
  But according to people briefed on its broad contours, the plan reflects the Ukrainian leader’s urgent appeals for more immediate help countering Russia’s invasion. Zelensky is also poised to push for long-term security guarantees that could withstand changes in American leadership ahead of what is widely expected to be a close presidential election between Harris and former President Donald Trump.
  
  The plan, people familiar with it said, acts as Zelensky’s response to growing war weariness even among his staunchest of western allies. It will make the case that Ukraine can still win — and does not need to cede Russian-seized territory for the fighting to end — if enough assistance is rushed in.
  
  That includes again asking permission to fire Western provided long-range weapons deeper into Russian territory, a line Biden once was loathe to cross but which he’s recently appeared more open to as he has come under growing pressure to relent.
  
  Even if Biden decides to allow the long-range fires, it’s unclear whether the change in policy would be announced publicly.
  
  Biden is usually apt to take his time making decisions about providing Ukraine new capabilities. But with November’s election potentially portending a major change in American approach to the war if Trump were to win, Ukrainian officials — and many American ones — believe there is little time to waste.

  Trump has claimed he will be able to “settle” the war upon taking office and has suggested he’ll end US support for Kyiv’s war effort.
  
  “Those cities are gone, they’re gone, and we continue to give billions of dollars to a man who refused to make a deal, Zelensky. There was no deal that he could have made that wouldn’t have been better than the situation you have right now. You have a country that has been obliterated, not possible to be rebuilt,” Trump said during a campaign speech in Mint Hill, North Carolina, on Wednesday.
  
  Comments like those have lent new weight to Thursday’s Oval Office talks, according to American and European officials, who have described an imperative to surge assistance to Ukraine while Biden is still in office.
  
  As part of Zelensky’s visit, the US is expected to announce a major new security package, thought it will likely delay the shipping of the equipment due to inventory shortages, CNN previously reported according to two US officials. On Wednesday, the US announced a package of $375 million.
  
  The president previewed Zelensky’s visit to the White House a day beforehand, declaring on the margins of the United Nations General Assembly his administration was “determined to ensure that Ukraine has what it needs to prevail in fight for survival.”

  “Tomorrow, I will announce a series of actions to accelerate support for Ukraine’s military – but we know Ukraine’s future victory is about more than what happens on the battlefield, it’s also about what Ukrainians do make the most of a free and independent future, which so many have sacrificed so much for,” he said.

  ‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence
  kraken
  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.
  kra30 at
  “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.”

  Water and life
  Eth Mixer
  Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.
  
  Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.
  
  “Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”
  
  However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids and extreme pressure.
  Yet another hypothesis suggests that organic molecules didn’t originate on Earth at all. Rather, they formed in space and were carried here by comets or fragments of asteroids, a process known as panspermia.
  
  “We still don’t know the answer to this question,” Zare said. “But I think we’re closer to understanding something more about what could have happened.”
  
  Though the details of life’s origins on Earth may never be fully explained, “this study provides another avenue for the formation of molecules crucial to the origin of life,” Williams said. “Water is a ubiquitous aspect of our world, giving rise to the moniker ‘Blue Marble’ to describe the Earth from space. Perhaps the falling of water, the most crucial element that sustains us, also played a greater role in the origin of life on Earth than we previously recognized.”
