Dark energy, what is it? Some theories about her

We have built very powerful telescopes that allow us to observe the Universe, spacecraft with which to reach the Moon, space stations, satellites and robots capable of examining a planet with total autonomy while we remain in our home.All this without understanding for sure how the Universe works, the laws that govern it and the engine that moves it.Many theories have been proposed to explain what scientists call the Dark Energy .Do you want to know some of them?

What is Dark Energy?

It is a good question for which scientists still do not have a clear answer, the truth is that it is not about the force of evil or nothing like that...When scientists talk about Dark Energy they refer to a force that is homogeneously found throughout the universe, occupying 70% of its total energy, and acting in a way mysterious interacting with the graved ad and filling the void.And until here, there seems to be more or less a general consensus in the scientific community, the discrepancy arises in the function that this energy plays within the Space.

Some like the scientist Edwin Hubble raise the possibility that this dark energy is responsible for the Constant Expansion of the Universe .Segun Hubble , the Space is in continuous expansion, phenomenon that showed through the measurements of the distances in the space, which were increasing as time went by, the immovable reference points remaining, tending to the isolation of the same.difficult to conceive in a limited space, which further reinforces that continuous expansion.

Dark energy, what is it? Some theories about her

Others, like Fritz Zwicky, think that dark energy might have the property of changing shape, called Quintessence , with which it could pass from a state of energetic fluid to another defined as dark matter, also of mysterious origin that is not visible in the electromagnetic spectrum even if it exists, as evidenced by the action it exerts on the orbit velocity of galaxies, playing a fundamental role in the formation of structures as well as in the evolution of galaxies.This strange capacity would influence slowing the expansion of the Universe.

Dark energy, what is it? Some theories about her

From Einstein's Theory of Relativity the Gravitational Dilatation Theory of Time emerges, another explanation for that phenomenon of expansion observed in the space called Energy Dark, in which it is stated that time passes at different rates in the different regions of the universe, creating the illusion of an expansion of Space .

Which of them will be in the truth?
