The Hole Argument

The Hole Argument concerns how we understand spacetime in physics. It suggests that if the universe’s geometry can be changed inside a certain region ("the hole") without altering observable phenomena, then multiple different "solutions" could explain the same reality. This raises questions about whether spacetime points have an independent reality or if only the relationships between objects matter. Essentially, it challenges how we interpret the nature of spacetime: is it a fixed stage with points that exist independently, or just a network of relationships reflecting matter and energy?
