Does a wormhole have length?

Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.

What dimension is a wormhole?

Primordial wormholes are predicted to exist on microscopic levels, about 10–33 centimeters. However, as the universe expands, it is possible that some may have been stretched to larger sizes.

What is the equation for a wormhole?

But a Stanford theoretical physicist has just come up with a new equation that suggests the key to finally connecting the two could be found in bizarre spacetime tunnels called wormholes. The equation is deceptively simple: ER = EPR.

Why are wormholes unstable?

Wormholes are so unstable because, in essence, they consist of two black holes touching each other, connected at their singularities to form a tunnel. If you cross a black hole’s event horizon, you’ll never escape. In order to overcome this problem, the entrance to a wormhole must be outside of the event horizon.

What does a wormhole look like in real life?

Wormhole visualized in 2D For a simplified notion of a wormhole, space can be visualized as a two-dimensional surface. In this case, a wormhole would appear as a hole in that surface, lead into a 3D tube (the inside surface of a cylinder), then re-emerge at another location on the 2D surface with a hole similar to the entrance.

Is it possible to visualize a three-dimensional wormhole?

Although a three dimensional wormhole is impossible to fully visualize, a two dimensional analogue can be constructed to aid visualization. Imagine an intrinsically flat, two dimensional, space as a folded piece of paper embedded in a higher three dimensional space, where a tube connects two distant points, A and B, on the paper.

What is the shape of the mouth of a winwormhole?

Wormholes contain two mouths, with a throat connecting the two. The mouths would most likely be spheroidal. The throat might be a straight stretch, but it could also wind around, taking a longer path than a more conventional route might require.

How far can a wormhole connect two universes?

Theoretically, a wormhole might connect extremely long distances such as billion light years, or short distances such as a few meters, or different points in time, or even different universes. In 1995, Matt Visser suggested that there may be many wormholes in the universe if cosmic strings with negative mass were generated in the early universe.
