The Einstein-Rosen Bridge (theoretical concept)

The Einstein-Rosen Bridge, often referred to as a "wormhole," is a theoretical concept in physics suggesting a tunnel-like connection between two different points in space and time. Formulated by Albert Einstein and Nathan Rosen, it arises from the equations of general relativity, which describe gravity's effect on the fabric of spacetime. In theory, if these bridges exist, they could allow faster-than-light travel between distant regions of the universe or even different universes. However, no experimental evidence supports their existence, and there are significant challenges, such as stability and traversability, that remain unresolved in scientific discussions.
