Dark energy may simply not exist!/¡La energía oscura simplemente puede no existir!

At the beginning of the last century, while developing the general theory of relativity, Albert Einstein realized that his equations led to the conclusion that the universe was not static as was believed at the time but was expanding so that, to achieve this static universe, he had to add his famous cosmological constant.
A principios del siglo pasado mientras desarrollaba la teoría general de la relatividad Albert Einstein se dio cuenta de que de sus ecuaciones se desprendía la conclusión de que el universo no era estático como se creía por entonces sino que se estaba expandiendo por lo que, para conseguir este universo estático, tuvo que añadir su famosa constante cosmológica.
Years later Edwin Hubble, who as you know, was a gentleman before being a telescope, discovered that the universe was actually expanding, observing the red shift of light from distant galaxies and Einstein removed that cosmological constant from his formula. which led him to declare that this had been "the biggest mistake of his career".
Años mas tarde Edwin Hubble que como sabéis, antes de ser un telescopio era un señor, descubrió que realmente el universo se estaba expandiendo, observando el corrimiento hacia el rojo de la luz de las galaxias lejanas y Einstein retiró de su fórmula esa constante cosmológica lo que le llevó a declarar que esta había sido "el mayor error de su carrera".
But the good thing about science is that it is continually questioning itself and subsequent observations made discovered in 1998 that the universe was not only expanding but that the expansion was accelerating, the logical thing would have been that the expansion, after the big bang, it was decelerating so the cosmological constant comes back on stage.
Pero lo bueno que tiene la ciencia es que continuamente se está cuestionando a si misma y posteriores observaciones realizadas descubrieron en 1998 que el universo no solo se expandía sino que la expansión se aceleraba, lo lógico hubiese sido que la expansión, tras el big bang, se fuese decelerando por lo que vuelve a salir al escenario la constante cosmológica.

This new constant is now called dark energy and it is a kind of repulsive gravity that permeates everything and that, according to the calculations of scientists, constitutes 70% of our universe, 21% being dark matter and only 4% of the universe It is made up of matter and energy that we all know and handle.
Esta nueva constante ahora se le llama energía oscura y es una especie de gravedad repulsiva que lo permea todo y que, según los cálculos de los científicos constituye el 70 % de nuestro universo siendo el 21 % materia oscura y tan solo un 4 % del universo está formado por la materia y energía que todos conocemos y manejamos.
But dark energy is not something that can be measured directly but comes out of complex formulas, so not all scientists agree on the conclusions obtained, but so far none of them have proposed any more successful alternative than said dark energy.
Pero la energía oscura no es algo que se pueda medir directamente sino que sale de complejas fórmulas, por lo que no todos los científicos están de acuerdo en las conclusiones obtenidas, pero hasta el momento ninguno de ellos ha propuesto ninguna alternativa más acertada que dicha energía oscura.

Now in a recent study by the University of Copenhagen a group of scientists propose that the effects attributed to dark energy could be caused by dark matter, if we assume that this dark matter can generate some kind of magnetic field and calculate the effect this would have on the universe, it would be unnecessary dark energy.
Ahora en un estudio reciente de la Universidad de Copenhague un grupo de científicos propone que los efectos que se atribuyen a la energía oscura podrían ser provocados por la materia oscura, si asumimos que esta materia oscura puede generar alguna especie de campo magnético y se calcula el efecto que esto tendría en el universo, la energía oscura sería innecesaria.
The bad thing is that this reason to explain the expansion of the universe is as complex and unhinged as that of dark energy, so it will surely be necessary to go much deeper into these studies and find a way to make some observations that confirm or discard these theories.
Lo malo es que esta razón para explicar la expansión del universo es tan compleja y desquiciada como la de la energía oscura por lo que seguramente habrá que profundizar mucho más en estos estudios y encontrar la manera de realizar algunas observaciones que confirmen o descarten estas teorías.

Hola @mauromar, seguramente hay que iluminarla para ver que hay allí.
Está muy original tu respuesta @elmundodexao
Hola @mauromar, sí que es complicado el trabajo de estas personas.
Very informative piece. Thanks
Hola!! @mauromar, hace un mes aprox vi un documental dobre el telescopio hubble y explicaban esa teoría de como el universo se va expandiendo, la realidad es muy interesante.
Seguro podamos comprobarlo cuando lancen el nuevo telescopio que dara imagenes mejores que el Hubble.
saludos y buen artículo
Gracias amiga.
More is unknown than is known. We know how much dark energy there is because we know how it affects the universe's expansion.
The modern science doesn't agree with the existance of dark energy.
Yeah.
This is very extraordinary, he researched about this realm.
His mind is very extraordinary, he is very genius.
Thank you for sharing about this nature.
We take far too much of what scientists say at face value. At present there is no evidence either for Dark Matter or Dark Energy. There are, however, alternate paths which astronomers and cosmologists have ignored for almost a century. Cosmologists often refer to cosmic gas and dust but the most common form of matter in the universe is plasma. Plasma has many interesting characteristics. For instance, light travelling through it will be red shifted. So how much of the observed red shift is due to velocity and how much is due to the vast amounts of interstellar plasma? Observation strongly suggests that Birkeland Currents connect planets with suns, suns with galaxies, galaxies to clusters, and clusters to each other.
Figure 1. Image showing a Birkeland Current. Plasma radiates in different colors as they are made of different elements. Multiple concentric layers of positive and negative charges flow past each other. Ions still exist away from the bright areas but do not produce synchrotron radiation. Therefore they are not detectable and 'Dark'. The Z-Pinch is where current densities and thus the concentration of matter are highest forming stars or galaxies.
It makes far more sense that the electric force is what gathers mass together to form larger bodies with gravity only taking over at shorter range. The force between a positive ion and a negative ion is 10 E36 times that of the gravitational force. Astronauts aboard the ISS showed by simple experiment that particles with very low mass would clump together quickly from static electricity alone. It is not difficult to imagine that the vast amounts of plasma -- in the non-radiating dark mode -- could account for the missing Dark Matter. It is suggested that the galaxy clusters in cosmic strings are held there by this Dark Matter but the more likely cause is Birkeland Currents. It is interesting that on the many popular science programs that plasma is rarely present. Birkeland Currents and Marklund Convection are never mentioned at all, though they've been confirmed by experiment.
Thank you @mscharen, it is a great comment.
a very useful post about dark energy, it really needs special research to prove the existence and absence of dark energy
Sir, Its seem to me their is no dark energy in the world.
