Wormholes: Theoretical Shortcuts Through Space-Time

Wormholes are hypothetical tunnels linking two distant points in space-time.
They are solutions to Einstein’s equations of general relativity.
A wormhole can be visualized as folding space so two faraway points touch.
If stable, they could allow faster-than-light travel across the cosmos.
Most theories suggest wormholes would collapse too quickly for use.
Exotic matter with negative energy might be needed to keep them open.
Wormholes could, in theory, connect not just places but also times.
No observational evidence for wormholes has ever been found.
They remain popular in science fiction as cosmic gateways.
Wormholes push physics to its limits, blending relativity and quantum theory.
