What is the news?<\/strong><\/h5>\n

Last week, an international team of researchers made the first putative direct detection of dark energy.<\/span>\u00a0<\/span><\/p>\n

The XENON1T experiment is the world\u2019s most sensitive dark matter experiment and was operated deep underground at the INFN\u00a0Laboratori\u00a0Nazionali\u00a0del Gran Sasso in Italy.\u00a0In this experiment scientists\u00a0noticed certain unexpected results. As per them, dark energy may be responsible for it.\u00a0Hence, this experiment can also be used to detect dark energy.<\/span>\u00a0<\/span><\/p>\n

What is dark energy\u00a0and dark matter?<\/span><\/b>\u00a0<\/span><\/h5>\n

Everything we see makes up less than 5% of the universe. About 27% is dark matter and 68% is dark energy.<\/span><\/b><\/p>\n

Dark energy<\/strong>\u00a0is\u00a0the mysterious form of energy that makes up about 68% of the universe.<\/strong> Dark energy has been noted as \u201cthe most profound mystery in all of science\u201d. <\/span><\/p>\n

While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of our universe.\u00a0<\/span><\/b>B<\/span>oth components\u00a0are\u00a0invisible. <\/span><\/p>\n

More is known about dark matter, since its existence was suggested as early as the 1920s, while dark energy wasn\u2019t discovered until 1998. Large-scale experiments like XENON1T have been designed to directly detect dark matter, by searching for signs of dark matter \u2018hitting\u2019 ordinary matter. Dark energy is even more difficult to find.<\/span>\u00a0<\/span><\/p>\n

When can we get direct detection of dark energy?<\/span><\/b>\u00a0<\/span><\/h5>\n

The team is hopeful that upcoming upgrades to the XENON1T experiment and similar experiments such as LUX-Zeplin \u2013 a next generation dark matter experiment located at the Sanford Underground Research Facility, and\u00a0PandaX-xT\u00a0\u2013 another project at China Jinping Underground Laboratory could help directly detect dark energy within the next decade.<\/span>\u00a0<\/span><\/p>\n
