(CNN) -- Nearly two years after it was sent up to the International Space Station, a giant particle physics detector has provided its first results in the search for the mysterious \"dark matter\" believed to be a major component of the universe. <\/p>\n
The international team running the Alpha Magnetic Spectrometer released its initial findings Wednesday at the European Organization for Nuclear Research, known as CERN, in Switzerland. <\/p>\n
The scientists are studying flux in cosmic rays, the charged high-energy particles that permeate space, for evidence of the invisible dark matter particles colliding with each other, leading to what is termed \"annihilation.\" <\/p>\n
A result of this would be a higher presence of the charged particles known as positrons, the antimatter counterpart of electrons. <\/p>\n
According to a CERN statement, the results announced Wednesday \"are consistent with the positrons originating from the annihilation of dark matter particles in space, but not yet sufficiently conclusive to rule out other explanations.\" <\/p>\n
How particle smasher and telescopes relate <\/p>\n
Over the last few decades, scientists have come to the conclusion that the universe's composition is only about 5% atoms -- in other words, the stuff that we see and know around us. That means the rest is stuff we can't see. About 71% is something called \"dark energy,\" and another 24% is \"dark matter.\" <\/p>\n
Research is ongoing to figure out precisely what these \"dark\" components are, because they do not interact with ordinary matter and have never been directly detected. <\/p>\n
