The theory of relativity, as presented by Albert Einstein, fundamentally changed our understanding of time and space, but it is crucial to clarify that it doesn’t imply that all truths are relative or subjective. Rather, it introduces a framework where measurements of time and distance can vary based on the observer's relative motion and gravitational field. This suggests that while perceptions may differ, there are still objective realities governed by the laws of physics.

In Walter Isaacson's "Einstein: His Life and Universe," he emphasizes that relativity challenges traditional notions of absolute measurements, yet it still rests on definitive scientific principles. Einstein's work illustrates that while our understanding of the universe may be influenced by perspective, it doesn't negate the existence of universal laws. Thus, the theory encourages a deeper appreciation for the complexities of reality rather than promoting a purely subjective view of the world.
