Scientists believe that more than 70% of the universe is made of dark matter, dark energy, or baryonic material.

OpenStudy (anonymous):

Actually, about 71.4% of the universe is made up of dark energy. About 24% is made up of dark matter, and only about 4.6% is made up of baryonic matter, the matter that we can see and interact with daily.

OpenStudy (anonymous):

OpenStudy (anonymous):

Yeah, dark energy accounts for about 70%.

Note that we don't know what form dark energy takes or what it actually is. It's called Dark Energy just because we know next to nothing about it.

Oh okay
