The universe may host a phenomenal number of wormholes: this theory that solves many mysteries

The universe is expanding at an increasing rate, a phenomenon that challenges our current understanding of physics.

What if this accelerated expansion was caused by tiny tunnels in space, invisible to the naked eye? Scientists are exploring the idea that micro-wormholes, born from the quantum vacuum, might hold the key to this cosmic mystery.


Wormholes, those hypothetical tunnels connecting distant points in the universe, could constantly emerge from the spatial vacuum due to subtle quantum effects. If proven, this theory would pave the way for quantum gravity, the long-sought unification of fundamental forces.

For decades, astronomers have observed an increasing expansion of the universe, contradicting Einstein's general relativity predictions. To explain this anomaly, the idea of mysterious dark energy, filling space and weakly interacting with matter, was proposed. Yet, this energy remains elusive.

A recent study, published in Physical Review D, offers a bold alternative to dark energy: continuously forming subatomic wormholes. These structures, distinct from classical quantum particles, could generate the energy necessary to explain the observed expansion.

The challenge lies in the complexity of calculations for these gravitational quantum phenomena. However, researchers have used an innovative approach, Euclidean quantum gravity, to estimate that roughly 10 billion wormholes created per cubic centimeter (0.06 cubic inches) per second could be sufficient for this task. Their model also suggests that dark energy could vary over time, in line with some recent observations.

Despite these theoretical advances, experimentation remains crucial to validate this hypothesis. Future space observations, increasingly precise, could test this intriguing and innovative theory.
