The original "true" story is regarded as a hoax.
The science fiction adaptation makes use of elements of the story, namely, following some of Einstein's unified field theories. Unified field theory suggests that under certain conditions gravity and electro magnetism weak and strong forces can be interrelated. That is say electro magnetic fields could generate gravitational fields. Furthermore with Einstein's gravitational theory, the inter relation of gravity and mass and time implying that potentially a mechanism for bending space and time could come from electro magnetic fields. The problem with all of this the necessary requisite energetic, a singularity might be a good example, necessary to achieve all of these even supposing such were possible. Physicist notably have yet, while having some possible contenders, to model an adequate unified field theory. The
movie nonetheless adapts an otherwise thriller romance come future time travel. While panned by the critics in its day, it still is something of interesting time capsule in film history.
