Cracking the mystery of dark matter is likely one of the most frustrating quests of physics. One lingering suggestion of the way to clarify among the challenges of dark matter is that the unusual substance arose earlier than the Big Bang. That second represents the most popular rationalization for the way the universe started, in a snapshot singularity that developed over billions of years into all the things that surround us. And if dark matter did come first, that modifications how scientists ought to hunt for the substance.
“The research revealed a brand new connection between particle physics and astronomy,” study creator Tommi Tenkanen, who is a physicist at Johns Hopkins University, said in a statement. “If dark matter consists of recent particles that have been born earlier than the Big Bang, they have an effect on the way in which galaxies are distributed within the sky in a novel means. This connection could also be used to disclose their identity and make conclusions in regards to the occasions earlier than the Big Bang, too.”
Tenkanen produced a mathematical model to probe how dark matter interacts with what physicists discuss with as scalar particles. In that class, scientists have up to now noticed the Higgs boson solely. And if dark matter is certainly older than the Big Bang, the substance would positively have interacted with scalar particles, he mentioned.
“If the dark matter has been actually a remnant of the Big Bang, then in lots of instances researchers ought to have seen a direct sign of darkish matter in several particle physics experiments already,” Tenkanen mentioned.
The truth that researchers have not seen such a sign but is troubling. However, Tenkanen stated his model might level to a special method for tackling the darkish matter query: specializing in astronomical observations. Specifically, he mentioned he sees the potential within the European Space Agency’s Euclid space telescope, which is scheduled to launch in 2022. That spacecraft is designed to map the perimeters of the universe, letting scientists look again about 10 billion years.
