How does Einsteins theory of relativity effect us today?

Einstein's theory of relativity fundamentally changed our understanding of space, time, and gravity, influencing modern technology and scientific advancements. For example, GPS satellites account for relativistic effects to provide accurate positioning, as time moves differently for satellites compared to those on Earth. Additionally, relativity plays a crucial role in understanding phenomena in astrophysics, such as black holes and the expansion of the universe. Overall, it shapes both our technological landscape and our comprehension of the cosmos.
