This is actually really easy to find on the internet. Try to google and research before posting a question, it saves time :).

68% dark energy 27% dark matter 5% ordinary matter

In 2015 the Planck satellite consortium released an analysis of data collected by the Planck satellite that showed this percentage break down of the universe’s mass/energy.

Ordinary matter: 4.9%

Dark Matter: 26.8%,

Dark Energy: 68.3%

    $\begingroup$ I kind of want to ask the obvious follow-up, how did it do this? But I feel that's also Google-worthy :). $\endgroup$ – Magic Octopus Urn Jan 17 at 15:01

    $\begingroup$ it didn't do it @MagicOctopusUrn, it obtained some data that was plugged into an cosmological model of the universe, and the numbers came tumbling out. $\endgroup$ – JCRM Jan 17 at 18:03
  • $\begingroup$ @JCRM hehe... I guess I shouldve said how did the super computer that proceased the data connect the "dots". $\endgroup$ – Magic Octopus Urn Jan 18 at 1:11
