Xenon1T Experiment: The XENON1T experiment is the world’s most sensitive dark matter experiment and was operated deep underground at the INFN Laboratori Nazionali del Gran Sasso in Italy.

Dark Energy and Dark Matter:

• The visible matter makes up less than 5% of the universe.
• The rest of the Universe is made of dark matter (27%) and dark energy (68%).
• Dark energy is the mysterious form of energy that makes up about 68% of the universe.
• Dark energy has been noted as “the most profound mystery in all of science”. While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of our universe. Both components are invisible.
• More is known 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 while dark energy is more elusive.
