    "abstract": "Einstein\u0027s dream of describing elementary particles as solutions of a\nclassical field theory is severely limited by our current understanding of\nNature. Quantum theory is inconsistent with any local realistic theory such as\nevolving topological structures in space. It is shown that allowing time\nreversal as an intrinsic part of the structure of elementary particles allows\ngeneral relativity to explain quantum theory in principle. Such structures may\nalso explain electric charge and spin-half.",
