Stephen Hawking theory proved right by man-made black hole
Stephen Hawking theory proved right by man-made black hole
Scientists have managed to simulate their very own black hole in their lab and witnessed how it began to glow. The black hole event horizon was created by a team of physicists from the University of Amsterdam, who used a chain of atoms in a single file to gain further understanding about the behaviour of a black hole. Its creation managed to prove Stephen Hawking's theory from 1974 where the black hole emitted a rare form of radiation. Sign up to our free Indy100 weekly newsletter They studied the properties of Hawking radiation through the creation of a black hole analog in the lab. According to Science Alert, Hawking radiation happens when "particles born from disturbances in the quantum fluctuations caused by the black hole's break in spacetime." The fact that the radiation exhibits a glow itself is in a strange space anomaly, as the event horizon of a black hole is supposed to be where neither light nor matter is able to get out. We all learn about the strength of a black hole in science class – and how we would all be inevitably sucked in as a result. This is possible due to its density within a certain range of the centre, so even an attempt at travelling beyond light speed (or any velocity in the universe for the matter) would not make this unavoidable. The fake black hole event also caused a rise in temperature that matched theoretical expectations of an equivalent black hole system, - but only when part of the chain extended beyond the event horizon, Science Alert reported. As a result, it is believed perhaps this entanglement of particles that straddle the event horizon plays a big role in generating Hawking radiation. Under simulations that began by mimicking spacetime thought of as "flat," scientists say the radiation was only thermal for a certain range of 'hop amplitudes'. So there may be certain situations where Hawking radiation can emit thermally - and could only be the case where gravity causes a change in the warp of space-time. "This can open a venue for exploring fundamental quantum-mechanical aspects alongside gravity and curved spacetimes in various condensed matter settings," the scientists wrote in their paper published by Physical Review Research.

McLaren set astonishing new F1 record after Lando Norris pit stop
McLaren set astonishing new F1 record after Lando Norris pit stop
McLaren recorded the quickest pit stop in Formula 1 history on Sunday at the Qatar Grand Prix. Lando Norris’ second stop at the Lusail Circuit, on lap 28, clocked in at 1.8 seconds – 0.02 seconds quicker than the previous record. That previous landmark of 1.82 seconds was set by Red Bull with a Max Verstappen stop at the 2019 Brazilian Grand Prix. But what makes this new record more astounding is that the tyres are heavier – 18-inch compared to 13-inch – on the current generation of cars. It means McLaren are firm favourites to secure the DHL Fastest Pit Stop Award this season. Red Bull had also set the previous-best time this season, with a 1.98 second stop for Sergio Perez in Budapest in July. Norris finished the race in third place as McLaren secured a second consecutive double podium with Oscar Piastri coming home in second place, behind race winner and 2023 world champion Max Verstappen. It was another excellent day for the papaya, 24 hours after Piastri claimed his first taste of victory in F1 after winning the sprint race. With five races left, McLaren are now just 11 points behind fourth-placed Aston Martin in the constructors’ standings after a mid-season resurgence. Norris is seventh in the world championship, four points clear of Mercedes’ George Russell, with Piastri ninth in the standings.
