“We do not know what dark matter is, but if it has anything to do with any scalar particles, it may be older than the Big Bang,” says astrophysicist Tommi Tenkanen at the Johns Hopkins University, who was not part of a 2019 University of Tokyo study that proposed the axion as a candidate for dark matter. The only fundamental scalar quantum field that has been observed in nature is the Higgs field-a field of energy that is thought to exist in every region of the universe.
Miguel Zumalacarregui was a Marie Curie Global Fellow at the Berkeley Center for Cosmological Physics prior to joining The Max Planck Institute for Gravitational Physics (Einstein Institute) in 2021. A Google Scholar, his research is directed towards finding new theoretical and observational approaches to the problem of cosmic acceleration, the nature of dark matter, and their connections to fundamental physics.
Future Laser Interferometer Gravitational-Wave Observatory (LIGO) alerts may likely come from a globular cluster, with the closest cluster residing about 7,000 light years from Earth. When a gravitational wave transit the Milky Way, it stretches and squashes space-time, making pulsars and the Earth jiggle.
