Sept. 27, 2021

An international team of researchers made the first putative direct detection of dark energy.

About:

  • Dark energy, the mysterious form of energy that makes up about 68% of the universe, has intrigued physicists and astronomers for decades.

  • Dark energy has been noted as “the most profound mystery in all of science”.

Dark energy Vs Dark matter

  • Everything we see – the planets, moons, massive galaxies, you, me, this website – makes up less than 5% of the universe.

  • About 27% is dark matter and 68% is dark energy.

  • While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of our universe.

  • 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.
