This theory could explain why 95% of the universe is missing



Scientists may have torn a decade-long puzzle around the fabric of the cosmos.

Up to 95 percent of the known universe is "missing", meaning it can not be explained by scientists and a newly discovered "dark liquid" could solve the puzzle.

The material scientists say that it has a negative mass, bringing together dark energy and dark matter in a single phenomenon.

It is widely believed that dark matter and dark energy – invisible substances that have never been observed by scientists – form parts of the Universe that modern physics can neither measure nor explain.

So far, however, scientists have failed to describe how the pair fits into the theoretical jigsaw of the cosmos. [1

9659002] DR. James Farnes, who led the University of Oxford team, said: "We now believe that both dark matter and dark energy can be combined to form a liquid that has some sort of 'negative gravity'." [19659002] It would suggest that the missing 95 percent of the cosmos had an aesthetic solution: we forgot to add a simple minus sign. The results were published in Astronomy & Astrophysics.

Our current model of the universe, called LambdaCDM, tells us nothing about how dark matter and dark energy look physical.

We only know about them because they have gravitational effects on other observable matter. [19659002] Scientists had previously suggested that the existence of negative matter could combine dark matter and energy into a single theory.

The idea was ruled out because it was thought that the material would become less dense with the expansion of the universe, which was not the case supported by observations of dark matter.

However, the Oxford team added another ingredient to the model: a "creation tensor" that allowed for the continued building of negative masses.

This meant that the universe expanded. The new material – the fluid with negative mass – was not diluted and was therefore included in calculations with dark matter.

Computer simulations of the team provided the first correct preparation diction of the behavior of dark matter halos that are supposed to hold together the tissues of galaxies.

Most galaxies rotate so fast that they should tear themselves apart, suggesting that an invisible "halo" of dark matter must be held together.

Simulations conducted as part of the new study predicted the formation of halos of dark matter similar to those detected by modern radio telescopes.

The theory of Farnes will come from tests conducted on innovative radio telescopes, including the Square Kilometer Array (SKA), which Oxford University is involved in building.
