In a new study, a team of researchers proposed that Dark Matter detectors could also search for the elusive force that is causing our Universe to expand (Dark Energy)!
About 25 years ago, astrophysicists noticed something very interesting about the Universe. The fact that it was in a state of expansion had been known since the 1920s, thanks to the observation of Edwin Hubble. But thanks to the observations astronomers were making with the space observatory that bore his name (the Hubble Space Telescope), they began to notice how the rate of cosmic expansion was getting faster!
This has led to the theory that the Universe is filled with an invisible and mysterious force, known as Dark Energy (DE). Decades after it was proposed, scientists are still trying to pin down this elusive force that makes up about 70% of the energy budget of the Universe. According to a recent study by an international team of researchers, the XENON1T experiment may have already detected this elusive force, opening new possibilities for future DE research.
The research was led by Dr. Sunny Vagnozzi, a researcher with the Kavli Institute for Cosmology (KICC) at the University of Cambridge, and Dr. Luca Visinelli, a Fellowship for Innovation (FELLINI) researcher (which is maintained with support from the Marie Sklodowska-Curie Fellowship) at the National Institute of Nuclear Physics (INFN) in Frascati, Italy. They were joined by researchers from the Institute de Physique Theórique (IPhT), the University of Cambridge, and the University of Hawai’i.
