Shedding new light on dark matter
No one has yet managed to show what dark matter is made of, even though it appears to make up over 80 percent of the mass in the universe. At Stockholm University a new kind of sensor is being built to study hypothetical particles called axions. If these invisible particles do in fact exist, they may provide a solution to the mystery of dark matter.
“We see the existence of dark matter in numerous wholly independent astrophysical observations, including galaxy rotation curves, in gravitational bending of light around large galaxy clusters, and in the cosmic microwave background radiation — the oldest light in the universe. But we still do not know what dark matter is,” says Jón Gudmundsson of Stockholm University.
Jón Gudmundsson is a researcher in physics and leads the research project "Tuning into Dark Matter", which also includes Nobel laureate Frank Wilczek.
