Scientists hear newborn black holes 'cry' – what does this cosmic sound reveal?
Scientists have detected gravitational waves. These waves are like cosmic whispers from newborn black holes. The sounds come from ripples in spacetime. Researchers are calling the phenomenon a "cry."
Two such events have been observed. One black hole's birth was highly unusual. It happened much sooner than expected. This suggests it might be a "second-generation" black hole.
This discovery confirms long-held theories. It provides direct evidence for Stephen Hawking's predictions. These sounds are the universe's way of singing.
This isn't the first time we've heard such cosmic events. Back in 2015, the LIGO experiment first detected gravitational waves. Those waves were from merging black holes. This new detection offers more insight into black hole formation. It opens new windows into the universe's past.
Future observatories aim to capture even fainter cosmic sounds. This could unlock more secrets of the early universe.
