This is How We’ll “See” the Universe’s First Second

The video explores the quest to understand the universe's origins by studying gravitational waves. It discusses how telescopes and observatories like LIGO have advanced our knowledge of cosmic events, confirming Einstein's theory of general relativity. The video delves into the concept of primordial gravitational waves, which could provide insights into the universe's inflationary period. It highlights the limitations of LIGO in detecting these waves and introduces the use of pulsar timing arrays, such as Nano Grav, to detect low-frequency gravitational waves. The video concludes with the potential of these discoveries to reshape our understanding of the universe's early moments.
