The Snazster writes: Dark matter remains one of the universe’s greatest mysteries, with no one quite certain what it is or where it came from, even though it may comprise as much as 80% of the universe (if ignoring the still hypothetical dark energy). A recent study at John Hopkins University is now suggesting that it may be older than the Big Bang itself, which would actually help explain why our previous searches for it have failed thus far. Although this is not a new idea, this is the first time the possibility has been described with calculations that seem to support it. “Using a new, simple mathematical framework, the study shows that dark matter may have been produced before the Big Bang during an era known as the cosmic inflation when space was expanding very rapidly,” reports ScienceDaily. “The rapid expansion is believed to lead to copious production of certain types of particles called scalars. So far, only one scalar particle has been discovered, the famous Higgs boson.”
“The new study also suggests a way to test the origin of dark matter by observing the signatures dark matter leaves on the distribution of matter in the universe,” the report adds. The study has been published in the journal Physical Review Letters.
