For nearly a century, scientists have worked to unravel the mystery of dark matter an elusive substance that spreads through the universe and likely makes up much of its mass, but has so far proven impossible to detect in experiments. Now, a team of researchers have used an innovative technique called quantum squeezing to dramatically speed up the search for one candidate for dark matter in the lab.
The findings, published today in the journal
Nature, center on an incredibly lightweight and as-of-yet undiscovered particle called the axion. According to theory, axions are likely billions to trillions of times smaller than electrons and may have been created during the Big Bang in humungous numbers enough to potentially explain the existence of dark matter.
