What does a wormhole look like and how does it differ from a black hole visually?

A wormhole is a theoretical tunnel-like structure that connects two separate points in spacetime. It is often depicted as a twisting, tube-like shape. A black hole, on the other hand, is a region of spacetime where gravity is so strong that nothing, not even light, can escape from it. Visually, a black hole appears as a dark, spherical object surrounded by a glowing accretion disk of matter being pulled into it. In contrast, a wormhole does not have a specific visual representation as it is a hypothetical concept.
