00:04dark energy is not well understood in fact we're not even 100 percent sure it actually exists it's
00:10something scientists have come up with to explain a variable with regards to physics and recently
00:14they calculated just how much dark energy might be out there they found that across the entire
00:19universe dark energy likely makes up some 69 percent of everything that means only 31 percent
00:26of the universe is made up of matter however that 31 doesn't only include the matter we can see and
00:31calculate but also dark energy's cousin dark matter and it just so happens that dark matter
00:36makes up an overwhelming proportion of all matter as well with astronomer muhammad abdullah saying
00:41about that quote about 80 is made up of dark matter whose mysterious nature is not yet known but may
00:47consist of some as yet undiscovered subatomic particles dark energy exerts a negative repulsive
00:53pressure in the universe sort of an opposite effect of gravity it's a force rather than a substance
00:58like matter and while we observe its effects on other objects scientists are still unsure about
01:03what it is or exactly how it works
