Solving the Dark Matter puzzle is one of the most frustrating tasks in physics. One suggestion, as some of the challenges of dark matter are, is that the strange substance was created before the big bang. This moment is the most popular explanation of how the universe began, in a snapshot of the singularity that has stretched billions of years into everything around us. And when dark matter comes first, it changes the way scientists search for the substance. The study revealed a new link between particle physics and astronomy, “said study author Tommi Tenkanen, a physicist at Johns Hopkins University.When dark matter is made up of new particles born before the Big Bang, they affect the way galaxies are uniquely distributed in the sky. This connection can be used to reveal their identity and also draw conclusions about the time before the big bang. Tenkanen developed a mathematical model to investigate how dark matter interacts with the so-called scalar particles. So far, scientists have only discovered the Higgs boson in this category. And if dark matter is actually older than the Big Bang, it would definitely have interacted with scalar particles, he said. If dark matter really were a remnant of the Big Bang, in many cases researchers would have seen a direct signal of dark matter in various particle physics experiments, “Tenkanen said. The fact that researchers have not yet seen such a signal is worrying. However, Tenkanen said his model may suggest another approach to dark matter management: concentrating on astronomical observations. In particular, he sees potential for the Euklid Space Telescope of the European Space Agency, whose launch is scheduled for 2022. The purpose of this spacecraft is to map the edges of the universe and give scientists a look back at about 10 billion years. The new research is described in an article published on August 7, 2109, in the journal Physical Review Letters.
