Story summary

Scientists have delved into the mysteries of the universe by analyzing gravitational waves from black-hole mergers. Their groundbreaking study, published in Physical Review Letters, reinforces the Cosmological Principle while revealing that one merger, GW200129, defied mirror symmetry. This suggests that precessing orbital planes are more common than thought, potentially unlocking new insights into quantum gravity and the universe's expansion.
