Physicists once again confirm that Einstein-Rosen bridges, the very wormholes that allow travel faster than light, exist. But they look like caterpillars writhing inside the quantum instability of black holes.
Problem of wormholes inside black holes
Nothing in space can move faster than light. But it is quite possible that there are passages in space that allow corners to be cut. And, according to a study recently published in the journal Physical Review Letters, these passages resemble caterpillars connecting black holes.
The authors of the study are scientists from Argentina and the United States. And indeed, they have returned to a fairly old problem. It is known that space contracts inside black holes. But there is a suggestion that at some point this contraction will be replaced by expansion. This concept is called a wormhole, or the Einstein–Rosen bridge.
No one knows where Einstein-Rosen’s bridge leads. It is quite possible that it leads to another time or another Universe. But in their work, scientists considered a much less exotic case, when they connect two black holes together.
Quantum Caterpillars
The researchers began by considering the simplest case, where a wormhole inside one black hole leads directly to another. They discovered that quantum uncertainty inside these objects prevents such a scenario from occurring.
But if the passage is curved in such a way as to bypass quantum uncertainties and at the same time has a lumpy structure, it can indeed exist. Such a tunnel resembles a caterpillar wriggling through quantum space.
This discovery revealed a direct mathematical connection between quantum chaos and wormhole size. The more random and chaotic the quantum state of black holes is, the more complex the physical wormhole connecting them becomes.
The discovery is extremely important, because until now it was believed that quantum instability on the surface of a black hole completely ruled out any movement. But now it seems that Einstein-Rosen bridges and quantum teleportation may be different manifestations of the same phenomenon, because researchers have been able to construct their theory only on the condition that black holes are in a state of quantum entanglement.
