One variety of these, also known as Einstein-Rosen Bridges, can be modeled as vacuum solutions to the Einstein field equations, combining a black hole and a white hole, but are so unstable that they vanish even before light can pass through.
These entities' name was first coined by American theoretical physicist John Archibald Wheeler, though German mathematician Hermann Weyl had already proposed a theory about them, in connection with his mass analysis of electromagnetic field energy. One variety of these, also known as Einstein-Rosen Bridges, can be modeled as vacuum solutions to the Einstein field equations, combining a black hole and a white hole, but are so unstable that they vanish even before light can pass through. Those are named for Schwarzchild, and Kip Thorne and Mike Morris published the first report on traversable varieties of these structures. For 10 points, name these entities, generally thought of as shortcuts in space-time.
