Kruskal-Szekeres Coordinates

Kruskal-Szekeres coordinates are a way to describe the space around a black hole, allowing us to visualize and understand its structure without the singularity affecting our predictions. Traditional coordinates can become unusable at the event horizon, but Kruskal-Szekeres coordinates extend smoothly through it. This method reveals that black holes have a rich geometry, connecting regions of spacetime that would otherwise seem isolated. By using these coordinates, scientists can explore how light and matter behave near and inside a black hole, enhancing our understanding of gravity and the universe’s limits.
