Research: New Theory can & # 39; explain missing 95 percent of the cosmos –


Scientists at the University & # 39; Oxford may have solved one of the biggest questions in modern physics, b & # 39; new card combines the dark matter and dark energy in & # 39; one phenomenon: Fluid possesses a "negative mass". If you had to push negative mass, it will accelerate to you. This surprising new theory can & # 39; also try to forecast that Einstein did 100 years ago.

Our most current and recognized model of the Universe, called LambdaCDM, tells us nothing about what dark matter and dark energy are similar physically. We know them only because of the gravitational effects to other observable matter.

This new model, published today in Astronomy and Astrophysics, By Dr. Jamie FARNE from Oxford e-Research Center, Department of Science Engineering, offers a new explanation. Dr. FARNE says: "We now think that both dark matter and dark energy could join in & # 39; liquid possesses type & # 39; ' negative gravity ", to reproduce the other material of & # 39; around. Although this question is given to us, suggests that our Kosmos is symmetrical as in & # 39; positive capabilities as well as negative."

The existence of & # 39; negative material previously excluded because it was believed that this material will become less dense as the Universe expands, contrary to our observations show that dark energy does not diminish maż- time. However, the research & # 39; Dr. FARNE apply "creating tension", which allows negative masses are constantly being created. Demonstrate that more and more negative masses are continually translated, this negative fluid mass with jiddilwixxix during the expansion of the Kosmos. In fact, the fluid appears to be identical to dark energy.

The theory & # 39; Dr. FARNE also provide the first correct prediction of the halos of dark matter. The majority of galaxies rotate so quickly and be taken apart, suggesting that "halo" invisible & # 39; dark matter must be kept together. The new research published today contains a computer simulation of the properties of & # 39; negative mass, which predicts the formation of & # 39; halos of & # 39; dark material such as inferred by & # 39; observations using & # 39; Modern radio telescopes.

Einstein provided the first hint of & # 39; dark universe exactly 100 years ago, when he discovered in his equations parameter known as "constant kożmoloġiċi", which we now know to be synonymous with & # 39; dark energy. Einstein called his kosmoloġiku known as constituent his young bigger, although modern astrophysical observations show that it is a real phenomenon. F & # 39; notes dating back to 1918, Einstein described his kostimonjoloġika constant, and wrote that "it is necessary theory modification so that the space act as & # 39; gravity & # 39; negative masses which are distributed throughout interstellar space. " It is therefore possible to predict negative Einstein own stuffed mass universe.

Dr. FARNE says: "The previous approaches to combining dark energy and dark matter have tried to modify the theory & # 39; Einstein on general relativity, which turned out to be a & # 39; challenging incredibly. This -approċċ new takes two old ideas that are known to be compatible with the theory of & # 39; Einstein – negative masses and creating & # 39; matter – and connect them together.

"The result looks pretty nice: dark energy and dark matter can join in & # 39; one substance, b & # 39; two effects simply be explained by the positive bulk material sails at sea & # 39; negative masses. "

theory Proof & # 39; Dr. FARNE will come from tests carried out by & # 39; radjopkju of known advanced radio as Square Kilometer Array (SKA), an international effort to build the largest telescope in the world where the University & # 39; Oxford collaborating.

Dr. FARNE adds: "There are still many theoretical and computational simulations issues to work through & # 39 ;, and LambdaCDM must start & # 39; nearly 30 years, but I'm anxious to see if this new extended version & # 39 ; LambdaCDM can bring & # 39; other evidence of exactly & # 39; observing our Cosmology. If true, suggests that the missing 95% of Kosmos had aesthetic solution: we forget in including a simple minus sign. "
