The premise behind the machine the scientist creates revolves around contacting people once they are dead. The machine constructed is an exact replica of Eric Dollard's Cosmic Induction Generator (CIG) that is used to harness the free flowing electrical induction that is all around us, known as Zero point energy, Orgone, Ether, etc.
In the movie the wound co-axial coils can clearly be seen on either side of the machine, with an magnetic rotary wheel in the middle where the induction is centralized. Replacing the wheel with a vacuum tube would create a galaxy like formation within the tube if placed within the coils.
All of this information is just now becoming popularized with the emergence of Electric Universe cosmology, to include people like "SuspicousObervers", Dollard, Arron of Energetic forums, and many more who are shining the light of the flaws of relativity brought to us by the plagiarism of Einstein even though he was well meaning. This is even discussed in the film at the local bar segment.
But, as the movie goes on to show, some things are not meant to be known, nor tampered with.
