How We Could Study the First Nanoseconds of the Universe

The video explains how telescopes act as time machines by observing light from the past. It introduces gravitational waves, predicted by Einstein, and their detection through events like black hole mergers. The video discusses primordial gravitational waves, their potential origins, and their significance in understanding the universe's birth. It explores methods for detecting these waves, including indirect methods like analyzing the cosmic microwave background and direct methods using interferometers and pulsars. Future projects like LISA aim to improve detection capabilities, offering insights into the universe's early moments.
