Dark Energy has been puzzling astrophysicists for a long time. They found out that the mysterious form of energy exists without knowing what exactly is it and what characteristics does it have. Dark energy is known as the driving force behind the accelerated expansion of the Universe.
Thanks to a new study led by the University of Cambridge that Phys.org reveals, Dark Energy might have finally been found. The researchers now suspect that Dark Energy might have caused some peculiar results obtained by the XENON1T experiment from Italy.
Dark Energy produced in the Sun?
Dark energy particles are now thought to had been produced in parts of the Sun that feature strong magnetic fields.
Dr. Sunny Vagnozzi from the Kavli Institute for Cosmology in Cambridge and also the paper’s first author, declared as quoted by Phys.org:
Despite both components being invisible, we know a lot more about dark matter, since its existence was suggested as early as the 1920s, while dark energy wasn’t discovered until 1998,
Large-scale experiments like XENON1T have been designed to directly detect dark matter, by searching for signs of dark matter ‘hitting’ ordinary matter, but dark energy is even more elusive.
According to NASA, about 68% of our Universe consists of Dark Energy. 27% is made of dark matter, another mysterious thing that scientists would like to unveil. Less than 5% of the Universe is made of the normal matter that we interact with every day. Scientists discovered even since about a century ago that the Universe is expanding due to the work of Edwin Hubble, but they couldn’t understand exactly why.
Future experiments are still needed to confirm if scientists had truly detected Dark Energy, so there’s no use opening the champagne just yet.
