Spacetime Ripples From the Dawn of The Universe? #sciencetime #spacescience #astronomy

In 2023, astronomers detected faint spacetime ripples, sparking intrigue about their origins, possibly dating back to the universe's dawn. The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) suspects these waves stem from merging supermassive black holes. Yet, this isn't the only theory. Alternatives include cosmic strings, phase transitions, and domain walls from the early universe, potentially linked to the Big Bang's aftermath.

These phenomena could offer insights into dark matter and dark energy, comprising 95% of the universe. Unraveling these signals is challenging, necessitating advanced detectors like the upcoming Laser Interferometer Space Antenna (LISA) and the proposed Atomic Experiment for Dark Matter and Gravity Exploration (AEDGE). As scientists prepare for these missions, precise calculations are key to interpreting future data and unlocking the mysteries of our cosmic origins.
