The fabric of spacetime might be woven by wormholes connecting virtual particle pairs, revealing that the vacuum of space is not truly empty due to quantum fluctuations. The Casimir force demonstrates the existence of virtual particle pairs, influencing the movement of metal plates in a vacuum. This force arises from the imbalance of uncertainty fluctuations inside and outside of the plates. Quantum entanglement suggests that the vacuum of space is interconnected by threads of entanglement, akin to a quantum net holding the universe together. Cutting these entanglement threads mathematically results in the discretization and disappearance of space, highlighting the crucial role of quantum entanglement in the structure of the universe.
