Normal stars are formed when this reaction from nuclear fusion, in which hydrogen atoms become soft form of helium becomes a more hard. However, when the universe was young, there are many dark material is abundant, particles made of wimps (Weakly Interacting Massive particles). These particles then join together and eliminate one another before nuclear fusion stars beginning to change. The result, the first stars appear very different than other stars we can see at this time. According to the researchers, this change because there is a process of evolution. Theory in this publication in the journal Physical Review Letters. In the report it is shown that the dependence on particles that are not seen by experts astrology, but actually really happened and there. And the physicist can not detect it. However, indirectly, evidence of the presence of particles is real. "Content is a dark three-quarters of the universe," said Chairman of the Research Team, Katherine Freese from the University of Michigan, U.S..
