Private conversations with Albert Einstein published as book
Records from Albert Einstein's final years are being published as a book around 20 years after their discovery, as transcripts of telephone conversations the physicist had between 1953 and 1955, publisher Heyne Verlag announced on Monday. The records by Johanna Fantova, considered to be Einstein's last close female friend, describe events from the last year and a half before the scientist's death at the age of 76. Einstein (1879-1955), who fled Nazi Germany for the United States in 1933, reportedly shared his daily experiences in US exile with Fantova over the phone. Fantova, who first met Einstein in Germany but also moved to the US, transcribed his statements with his consent, the publisher said. The 62-page typescript in German was discovered by chance in 2004 at the Firestone Library of Princeton University, where Fantova once worked as a curator. The materials lay unprocessed in the archive for a long time. The diary entries are now set to be published for the first time in an annotated edition with additional findings on September 24. The title of the book by Peter von Becker is: "I am a Magnet for All the Maniacs. The Einstein Transcripts – His Life, His Last Love, His Legacy." In the diary, Einstein - who revolutionized physics with his Theory of Relativity - shares his thoughts on politics, science, everyday life and love. For instance, he criticized the arms race of the superpowers and the rearmament of Germany, and commented on the conflict between Israelis and Palestinians, according to the publisher.

Are female footballers' performances being accurately measured?
"UEFA Women's euro 2025 had a lot to live up to after England 2022 set new standards across the board with prolific goalscoring feats and unprecedented stadium crowds. However, the tournament in Switzerland is raising the bar even more across the board." When reviewing the group stage of the competition on July 17, the Union of European Football Associations (UEFA) made no effort to hide its delight. The day before, in Geneva, more than 26,000 fans attended the match between Italy and Norway, once again setting a new benchmark for a quarterfinal not hosted by the home nation. However, as UEFA pointed out, "the record may not last long," with France set to face Germany in Basel on July 19 for a spot in the semifinals. While the tournament's success appears evident, are fans truly recognizing the performances of the women's teams? That was the question raised on June 26 by Einstein, a popular science show on the German-speaking Swiss public channel, which had grown tired of the often condescending judgments about female players – who are supposedly slower, less technical and more error-prone, especially in goalkeeping − than their male counterparts.

Astronomers spot the exact moment a new planet system is being born around an alien star
When you buy through links on our articles, Future and its syndication partners may earn a commission. For the first time ever, scientists have captured incredible images of an alien star system being born. The image shows the very earliest moments of planet formation, when hot minerals are just beginning to solidify around a distant star, according to a statement. The researchers published their findings July 16 in the journal Nature. Two telescopes worked together to reveal outflows of hot minerals around HOPS-315, which is a baby star like our sun roughly 1,300 light-years from Earth. Initially, NASA's James Webb Space Telescope (JWST) spotted "stuff coming from close to the star, but it wasn't in the planet-forming region," study co-author Edwin Bergin, a star formation specialist at the University of Michigan, told Live Science. His team then used the Atacama Large Millimeter/submillimeter Array (ALMA), which is a set of antennas in the Chilean desert, to trace the outflow back to the protoplanetary disk — the dense disk of matter around a young star, where clumps of gas and dust can collapse into larger objects like planets. "Then that unlocked everything," Bergin said. It's the first time that planet-forming solids have ever been detected, he said – which could help researchers better understand how our own solar system was born. Related: Scientists discover rare planet at the edge of the Milky Way using space-time phenomenon predicted by Einstein Our solar system came into existence roughly 4.5 billion years ago in a cloud of gas and dust. As our sun formed and evolved, other materials gradually condensed into small solids, which grew by colliding and accreting into asteroids and comets, then in some cases, planetesimals and planets. The very earliest phases of this process are tough to spot in other systems, Bergin said, and the phase lasts just 100,000 to 200,000 years, he noted. But learning more about what happens in this moment is crucial, because when minerals begin to condense, organics also form. The new image shows carbon monoxide – represented in orange – blowing away from the star in a butterfly-shaped outflow, with a blue jet of silicon monoxide shining like an alien spine. A disk of gaseous silicon monoxide surrounding the area was also revealed, just as the gas was solidifying into silicates.

Other research using ancient meteorites – formed in this same era – show these space rocks are full of crystalline minerals, containing silicon monoxide. These solids are always moving about in the hot and windy conditions of a young star system, creating a rich environment for rocks to bind to each other. "The story of planetary formation is the story of motion and movement," Bergin noted. The researchers are hoping to use ALMA again to probe other young star systems that may have similar outflows, he added.

Scientists detect record-sized merger of black holes
Scientists have detected the largest black hole merger ever recorded by gravitational wave observatories, occurring approximately 10 billion light years from Earth. The collision involved two black holes, each over 100 times the mass of the sun, resulting in a new black hole up to 265 times more massive than the sun. The event, designated GW231123, was detected by the Ligo Hanford and Livingston Observatories in the US on November 23, 2023. Researchers noted the black holes were spinning extremely rapidly, near the limit allowed by Einstein's theory of general relativity, posing a challenge to current scientific models. This significant discovery pushes the boundaries of gravitational-wave astronomy and will be presented at the GR-Amaldi meeting in Glasgow in July.

Scientists discover the most massive crash of two black holes, each bigger than 100 Suns
The outer space has been home to mysterious, invisible giants with the power to bend space and time called Black holes. But recently, astronomers detected something so unique that it's forcing experts to rethink what we know about how black holes form and evolve. The discovery includes two black holes, whose size is more massive than 100 suns, crashing into one another in a collision that sent ripples through the fabric of space-time. In fact, the mass and spin of the black holes don't match what current models predict. This has given rise to new questions and possibilities about the life and growth of these cosmic powerhouses. The largest recorded black hole merger is a massive event named GW231123. Detected by the LIGO observatories in the US, along with partner detectors Virgo in Italy and KAGRA in Japan, this event involved two massive black holes, weighing roughly 100 and 140 times the mass of the sun. When they collided, they sent faint ripples through space-time called gravitational waves , a phenomenon first predicted by Einstein in 1915. 'These amazing detectors are really the most sensitive measuring instruments that human beings have ever built,' said Mark Hannam, head of the Gravity Exploration Institute at Cardiff University and a member of the LIGO Scientific Collaboration. 'We're observing the most violent and extreme events in the universe through the smallest measurements we can make.' Something that sets this event apart is the size and speed of the black holes involved. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Die intelligentere Art, Ihre Anlageziele zu erreichen eToro Learn More Undo 'The individual black holes are special because they lie in a range of masses where we do not expect them to be produced from dying stars,' said Charlie Hoy, research fellow at the University of Plymouth and also part of the LIGO collaboration. This unusual mass range is known as the 'mass gap', meaning a theoretical range between about 60 and 130 solar masses where traditional star death isn't expected to create black holes. According to Hannam, 'There's a range of masses where we think that it's not possible for black holes to form that way. And the black holes from GW231123 live bang in the middle of that gap.' To explain this, researchers believe these black holes may be the result of earlier black hole mergers, which could essentially be a cosmic chain reaction. 'You can have this process where you just build up more and more massive black holes,' Hannam explained. Supporting this theory is the fact that the black holes appeared to be spinning near their physical limits. 'So far, most black holes we have found with gravitational waves have been spinning fairly slowly,' Hoy noted. 'This suggests that GW231123 may have formed through a different mechanism… or it could be a sign that our models need to change.' 'This new merger is very hard to explain in other ways,' said Zoltan Haiman, professor at the Institute of Science and Technology Austria, suggesting that these may be remnants of multiple generations of black hole mergers. Going ahead, future detections could reveal whether this record-breaking collision was a rare one-off or a clue to a much larger population of heavyweight black holes hiding in the universe.
