Understanding Spacetime
The concept of spacetime merges space and time into a unified four-dimensional framework, essential for understanding relativity. By converting time into a spatial dimension using the speed of light, we achieve Lorentz invariance, allowing for meaningful comparisons between time and space intervals. This approach not only clarifies the nature of distances in the universe but also explains why light years serve as a natural unit of measurement in astronomy.In this clip
