Explanation:
Detailed explanation-1: -Planck mapped out the distortions in the CMB due to gravitational lensing caused by dark matter’s presence. This all-sky map shows where the dark matter is in the universe; darker blue areas show greater dark matter density, and lighter colors show areas of less dark matter density.
Detailed explanation-2: -The CMB has also enabled cosmologists to estimate the total energy density of the Universe that comprises dark energy as approximately 0.71. Putting all this together gives the following breakdown of the total matter/energy content of the Universe: 4.9% ordinary matter, 26.8% dark matter and the rest dark energy.
