    Universe’s Missing Matter Found by FRBs
    A landmark study led by the Center for Astrophysics | Harvard & Smithsonian (CfA) has pinpointed the Universe’s “missing” matter using Fast Radio Bursts (FRBs)— brief, bright radio signals from distant galaxies— as a guide. This artist’s conception depicts a bright pulse of radio waves (the FRB) on its journey through the fog between galaxies, known as the intergalactic medium. Long wavelengths, shown in red, are slowed down compared to shorter, bluer wavelengths, allowing astronomers to “weigh” the otherwise invisible ordinary matter.
