what is a wormhole

A wormhole is a hypothetical structure connecting disparate points in spacetime. It is a tunnel-like connection through space-time that connects two distant points in space or time via a tunnel. Wormholes are predicted by the theory of general relativity. They are based on a special solution of the Einstein field equations. A wormhole can be visualized as a tunnel with two ends at separate points in spacetime. Wormholes contain two mouths, with a throat connecting the two. The mouths would most likely be spheroidal, and the throat might be a straight stretch or could wind around, taking a longer path than a more conventional route might require. While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Wormholes might occur naturally at microscopic scales in the quantum foam, the roiling nature of space-time at the very tiniest of scales due to those same quantum energies. In that case, wormholes might be popping in and out of existence constantly. However, its not clear how to "scale up" those wormholes to sizes big enough for humans to walk through and keep them stable. If a wormhole contained sufficient exotic matter, whether naturally occurring or artificially added, it could theoretically be used as a method of sending information or travelers through space.
