Description:

The Time Vortex, also known as the Time and Space Vortex, the Space-Time Vortex, and simply The Vortex, was the plane/dimension through which all time travellers passed. Space-time machines were able to pass through the vortex, including TARDISes and vortex manipulators.
Time and space, according to Einstein's theories of relativity, are woven together, forming a four-dimensional fabric called "space-time." The tremendous mass of Earth dimples this fabric, much like a heavy person sitting in the middle of a trampoline. Gravity, says Einstein, is simply the motion of objects following the curvaceous lines of the dimple.
If Earth were stationary, that would be the end of the story. But Earth is not stationary. Our planet spins, and the spin should twist the dimple, slightly, pulling it around into a 4-dimensional swirl.
