What if the universe hides shortcuts through space and time — and what if we’re not allowed to use them?

Wormholes appear naturally in Einstein’s equations: tunnels through spacetime that could connect distant stars, galaxies, or even different moments in time. They are mathematically beautiful… and physically cruel.

In this video, we take a slow, thoughtful journey through the physics of wormholes — from Einstein and Rosen’s original bridges, to black holes and white holes, to negative energy, the Casimir effect, and the deep problem of causality.

Could exotic energy stabilize a wormhole?
Could shortcuts through space become shortcuts through time?
And does the universe enforce a kind of “chronology protection” to stop paradoxes before they begin?

This is not science fiction hype. It’s a contemplation on what modern physics allows, what it forbids, and why mathematics is often more generous than reality.

Even if we never build a wormhole, they teach us something profound about spacetime, geometry, and the limits of knowledge itself.

The universe may have tunnels.
The real question is whether we’re allowed to use them.
