According to the physical cosmology and astronomyDark Energy is an unknown form of energy which is hypothesized to permeate all of the space, tending to accelerate the expansion of the universe. Since the 1990s the Dark energy is the most accepted hypothesis to explain the observations that indicated that the universe is expanding at an accelerating rate.

The nature of dark energy remains matters of conjecture but we know one thing for sure that it’s more hypothetical than dark matter. Well… it’s thought to be not very dense but very homogeneous and is known to interact through the gravity and none any of the fundamental forces.

For many decades astrophysicists crunching the numbers, but no matter how much they crunch the universe simply doesn’t add up in ant way. The “fabric” of the cosmos– its keep growing outward faster and faster, Even though the gravity is pulling inward on space-time. The astrophysicists have proposed an invisible agent to and it’s called “Dark Energy”.

 

If we talk about its most widely accepted model then dark energy known as a “cosmological constant”: A “negative pressure” from space own inherent property which is driving space apart

The new dark energy created because of space expands in a rapid way with each passing time and with it the more space is created as well. When the scientists observed the rate of expansion they found out that if we sum all of the  energy then it must make up more than 70 percent of the total contents of the universe, but it still remains question how to look for it.

Well in the topic of a study released in August 2015, in recent years the best researchers have been able is narrow in a bit on where dark energy might be hiding.

Also, there is some evidence of dark energy presents but we only knew very little brief of dark energy so we can say it’s still unknown for us.

IN SPACE: In this handout from NASA/ESA, an artist’s concept illustrates a quasar, or feeding black hole. NASA’s Wide-field Infrared Survey Explorer (WISE) revealed millions of potential black holes in its survey of the sky in 2011. The WISE telescope, which ceased operation is February of 2011 after it ran out of coolant to keep its electronics cool, made the full sky image and was released to the public in March with hopes of astronomers making discoveries.
