A new paper proposes that the Universe started with two Big Bangs, linking the origins of the Universe and the nature of dark matter. The prevailing theory suggests that ordinary matter and dark matter were created simultaneously, but the new theory suggests that dark matter could have had a different origin. Testing this theory is challenging, as experiments currently depend on interactions beyond gravity, but the detection of gravitational waves offers hope for further investigation in the future. #Space • #Sciene • #BigBang
