In a former gold mine a mile underground, inside a titanium tank filled with a rare liquefied gas, scientists have begun a search for what so far has not been able to find: dark matter. Scientists are pretty sure invisible objects make up most of the mass of the universe and say we wouldn’t be here without them – but they don’t know what they are. The race to solve this great mystery has taken one team to the depths beneath Lead, South Dakota. The question for scientists is basic, says Kevin Lesko, a physicist at Lawrence Berkeley National Laboratory. “What is this great place I live in? Right now, 95% of it is a mystery.” The idea is that a mile of dirt and rock, a giant tank, a second tank, and the world’s purest titanium will block out nearly all of the cosmic rays and particles that glide around – and penetrate – all of us every day. But dark matter particles, scientists say, can avoid all those obstacles. They hoped someone would fly into a vat of liquid xenon in the inner

Origin of ‘ghost particles’ DISCOVERED: Tiny bodies that pass through our body and planet undetected emitted from galactic cores fed by supermassive black holes in outer space ‘Ghost particles,’ or neutrinos, are particles that originate from outer space These particles have no mass and hardly interact with matter Scientists believe they came from the core of a galaxy that was fed by a supermassive black hole Blazars are known for emitting bright beams of light and wind and are thought to also produce cosmic rays By Stacy Liberatore For Dailymail.com Published: 2:04pm EDT, July 25, 2022 | Updated: 2:18 p.m. EDT, 25 July 2022 Extraterrestrial ‘ghost particles’ likely originate from the cores of galaxies fed by supermassive black holes, according to a new study that could unravel the mystery of subatomic particles that formed before the universe. Ghost particles, or neutrinos, have baffled scientists since they were firs

Some of the brightest and most energetic objects in the Universe are the mystery source of high-energy cosmic neutrinos, new research has confirmed. A comprehensive analysis has been convincing enough to link the galaxies that host the fiery cores known as blazars with these mysterious particles. It’s a result that provides a completely unexpected solution to a problem that has kept astrophysicists scratching their heads for years. “The results provide, for the first time, irrefutable observational evidence that the PeVatron blazar sub-sample is a source of extragalactic neutrinos and thus an accelerator of cosmic rays,” said astrophysicist Sara Buson of the Julius Maximilian University of Würzburg in Germany. Neutrinos are the odd little things at the best of times. These subatomic particles are ubiquitous and are among the most abundant in the Universe. However, their mass is almost zero, they are electrically neutral, and they interact very little with anything else in the universe

This time to prove the existence of another mysterious substance – dark matter. Although most scientists believe dark matter i
