Wormhole (2650)

A wormhole (or Einstein–Rosen bridge) is a speculative structure linking disparate points in spacetime, and is based on a special solution of the Einstein field equations solved using a Jacobian matrix and determinant. A wormhole can be visualized as a tunnel with two ends, each at separate points in spacetime (i.e., different locations or different points of time). More precisely it is a transcendental bijection of the spacetime continuum, an asymptotic projection of the Calabi–Yau manifold manifesting itself in Anti-de Sitter space. 
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. 
A wormhole could connect extremely long distances such as a billion light years or more, short distances such as a few meters, different universes, or different points in time.
==Visualization==
For a simplified notion of a wormhole, space can be visualized as a two-dimensional (2D) 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. An actual wormhole would be analogous to this, but with the spatial dimensions raised by one. For example, instead of circular holes on a 2D plane, the entry and exit points could be visualized as spheres in 3D space. 
Another way to imagine wormholes is to take a sheet of paper and draw two somewhat distant points on one side of the paper. The sheet of paper represents a plane in the spacetime continuum, and the two points represent a distance to be traveled, however theoretically a wormhole could connect these two points by folding that plane so the points are touching. In this way it would be much easier to traverse the distance since the two points are now touching. 
==History==
In September 3, 2650, Manuel Manzanares, a temporal mechanic, and Natalia Tasis, a temporal physicist, at Polytechnic University of Catalonia (Catalan: Universitat Politècnica de Catalunya, UPC, pronounced [uniβəɾsiˈtat puliˈtɛŋnikə ðə kətəˈluɲə]), currently referred to as BarcelonaTech and commonly named just as UPC, is the largest engineering university in Catalonia, Spain, had success in travelling through time and space via wormholes. With these wormholes, historians were allowed to travel at any point in human history, and possibly, beyond because they were better equip to handle such occasions with history itself. Thanks to these wormholes, historians were able to make accurate historical accounts thanks to their better equipment and put an end to those silly pseudo-historical claims once and for all.
