The universe is expanding, and recent observations reveal that galaxies are moving away from us. This phenomenon is not static; instead, the pace of this expansion is increasing over time. This discovery challenges our understanding of cosmic dynamics and introduces the concept of dark energy, which is thought to drive this acceleration.

Bill Bryson, in his book "A Short History of Nearly Everything," presents these complex ideas in an accessible manner. He explores the implications of an expanding universe, reflecting on how our understanding of space and time continues to evolve as new evidence comes to light, reshaping our perception of existence.
