Ripples in spacetime may have revealed the first evidence of tiny black holes born during the Big Bang. This discovery, if confirmed, could fundamentally reshape our understanding of the universe's earliest moments and the nature of its most elusive component.
Gravitational waves, the subtle distortions in the fabric of spacetime predicted by Einstein, appear to have provided this tantalizing clue. The signal suggests the existence of so-called primordial black holes, which would have formed not from collapsing stars but from density fluctuations in the hot, dense soup of the infant cosmos.
