Scientists are working on methods to date back the birth of our universe, even before the Big Bang. One way is through the cosmic microwave background radiation, the leftover glow from the early universe. By studying its fluctuations, scientists may be able to gain insights into the universe's initial conditions and possibly uncover evidence of events prior to the Big Bang. Additionally, astrophysicists are exploring the properties of gravitational waves, distortions in spacetime caused by massive objects, to potentially detect signals from the universe's earliest moments. These efforts aim to push the boundaries of our understanding and uncover the mysteries surrounding the origin and evolution of our cosmos.
