Let's talk about wormholes, black holes, and white holes. According to Einstein's General Theory of Relativity, all three theoretically exist. However, of the three, humanity has only confirmed the existence of black holes with physical evidence.
Wormholes and white holes, on the other hand, remain theoretical—more science fiction than fact. But in hindsight, that's to be expected.
The theory suggests that black holes and white holes are connected via a wormhole, forming a bridge through spacetime. Matter falling into a black hole would theoretically pass through the wormhole's "throat" and emerge from a corresponding white hole.
The issue? To confirm the existence of a wormhole, we would have to send something through a black hole, make observations—and survive the journey.
This raises another important question:
"Why haven't we found white holes?"
