The Planet 9 theory is making scientists question the rules of our existence
In space, discoveries continue to be made that challenge scientific beliefs, as distant objects reveal the solar system is much bigger than first thought and the observation was previously made that a part of the sun is broken. Now, there is evidence to suggest the existence of a ninth undiscovered planet that is at the very edge of the solar system and could point towards evidence that our understanding of gravity is wrong. The discovery was made by two scientists who studied the effects that the Milky Way galaxy had on objects in the solar system’s outer edge. Galaxies are able to rotate extremely fast without any of their contents escaping, and most experts believe that the existence of dark matter might explain why. Dark matter is invisible and does not emit, nor reflect light, and it is hypothesized that galaxies are surrounded by dark matter rings that bind the galaxies together in their own gravitation pull and stop them from emitting material. But now, the gravitational theory of Modified Newtonian Dynamics (MOND) may suggest that dark matter is not why galaxies stay intact despite staggering rotational speeds. Instead, some believe that under the rotational velocities experienced by galaxies, a new kind of gravitational behaviour occurs. Case Western Reverse scientist Harsh Mathur, explained: “MOND is really good at explaining galactic-scale observations, but I hadn’t expected that it would have noticeable effects on the outer solar system.” Planet 9 comes into play because objects in the Kuiper belt (the disk that surrounds the outer edges of the solar system) were observed clustering and exhibiting orbital anomalies that do not occur with other objects in the belt. Experts believe this may be due to the presence of an undiscovered ninth planet, as this is a phenomenon that occurred before with the discovery of new planets as their gravitation pull attracts other solar system objects. Katherine Brown, Hamilton College professor of physics, said: “We wanted to see if the data that support the Planet Nine hypothesis would effectively rule out MOND.” Their study revealed that the hypothesis could be correct and could point towards the existence of Planet 9, but they urged that their dataset was very small, so no definitive conclusions could be made. Brown explained: “Regardless of the outcome, this work highlights the potential for the outer solar system to serve as a laboratory for testing gravity and studying fundamental problems of physics.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Nasa opens up pieces of a distant asteroid transported back to Earth
Nasa has revealed chunks of a distant asteroid that were transported back down to Earth. The dark, dusty sample comes from a 4.5-billion-year-old asteroid, and might include the “building blocks of life”, the space agency said. Already, the material from the asteroid Bennu has been found to include high-carbon content and water, the space agency said. But it will be distributed around the world with a view to finding out everything from the history of our solar system to how life came about. Scientists and space agency leaders showed photos and video of the asteroid material - returned to Earth last month - at a live streamed event at the Johnson Space Centre in Houston, Texas. The display came after a capsule containing an estimated 250g of rocks and dust collected from asteroid Bennu, touched down in the Utah desert near Salt Lake City on September 24. Nasa has said it was “the biggest, carbon-rich asteroid sample ever delivered to Earth”, and its contents have now been hailed as “scientific treasure”. Nasa administrator Bill Nelson said the sample will “help scientists investigate the origins of life on our own planet for generations to come”. He added: “Almost everything we do at Nasa seeks to answer questions about who we are and where we come from. “Nasa missions like Osiris-Rex will improve our understanding of asteroids that could threaten Earth while giving us a glimpse into what lies beyond. “The sample has made it back to Earth, but there is still so much science to come - science like we’ve never seen before.” Almost 60 million miles away, asteroid Bennu is a 4.5-billion-year-old remnant of our early solar system and scientists believe it can help shed light on how planets formed and evolved. The spacecraft launched on September 8 2016 and arrived at Bennu in December 2018. It dropped the samples off sealed in a capsule last month. “Already this is scientific treasure,” said the mission’s lead scientist, Professor Dante Lauretta, of the University of Arizona on Wednesday. In a statement, he added: “As we peer into the ancient secrets preserved within the dust and rocks of asteroid Bennu, we are unlocking a time capsule that offers us profound insights into the origins of our solar system. “The bounty of carbon-rich material and the abundant presence of water-bearing clay minerals are just the tip of the cosmic iceberg. “These discoveries, made possible through years of dedicated collaboration and cutting-edge science, propel us on a journey to understand not only our celestial neighbourhood but also the potential for life’s beginnings. “With each revelation from Bennu, we draw closer to unravelling the mysteries of our cosmic heritage.” Nasa‘s mission goal was to collect was 60 grams of asteroid sample. But when the canister lid was opened, Nasa said scientists discovered “bonus material” covering the outside of the collector head, canister lid, and base. There was so much extra material it slowed down the process of collecting and containing the primary sample, Nasa said. Scientists are not sure exactly how much of Bennu they brought back because the main sample chamber has not yet been opened. Mr Lauretta said: “It’s been going slow and meticulous, but the science is already starting.” He said there is “a whole treasure chest of extraterrestrial material” still to be examined. During Wednesday’s press conference, Osiris-Rex sample analyst Daniel Glavin added: “This stuff is an astrobiologist’s dream, I just can’t wait to get at it. “We’re going to learn so much about the origin of the solar system, the evolution and potentially how even life started here on Earth.” Additional reporting by agencies Read More ‘Ring of fire’ solar eclipse this month will be last until 2046 Prada to design Nasa’s next-gen space suits for Artemis astronauts 1.2 mile-high ‘dust devil’ spotted on Mars by Nasa’s Perseverance rover Rover captures one-mile-high whirlwind on Mars Earth hit by a huge solar storm that would devastate civilisation, trees show Scientists see afterglow from huge planets crashing into each other for first time

AI is using vast amounts of water
Artificial intelligence is using gallons upon gallons of water. Microsoft alone used more than 2,500 Olympic-sized swimming pools of water in its data centres last year. The latest numbers are leading to yet more questions about the sustainability and environmental dangers of the growth of artificial intelligence and related technology. Artificial intelligence requires vast computing resources, undertaking deeply complex calculations on behalf of people around the world. AI systems tend to be run in the cloud rather than on individual people’s computers, meaning that companies running them must operate vast server farms to deal with the queries of their users. Those server farms in turn need to pump in water to cool themselves down, because of the heat generated by those computers. That has long been a concern for environmentalists, but the sharp growth in artificial intelligence has led to even more use. Microsoft’s water consumption rose 34 per cent between 2021 and 2022, according to its latest environmental report, highlighted by the Associated Press. It was up to almost 1.7 billion gallons. Not all of that is from artificial intelligence. But Shaolei Ren, a researcher at the University of California, Riverside working to better understand the environmental impact of AI told the AP that the “majority of the growth” is because of the technology. Google also said that its water use had increased by 20 per cent over the same period. That varied across its different data centres, which are based in different parts of the US. For each 5 to 50 prompts, or questions, put to ChatGPT, it uses 500 millilitres of water, according to a paper that will be published by Professor Ren and his team later this year. Many technology companies have expressed concerns about their own water use, and how to minimise any negative effects of their data centres. The environmental concerns can be especially pressing because the use of water can be focused in particular areas around a data centre, meaning that the damage may not be spread. Google said last year for instance that “Wherever we use water, we are committed to doing so responsibly”. That includes analysing where water is being used and how much stress it might put on the surrounding area, for instance.
