One of the key concepts that make LENR go is dualism. Einstein first came up with the concept of dualism when he worked on the theory of special relativity. The Einstein March 1905 paper treated light as particles, but special relativity sees light as a continuous field of waves. Such a contradiction took a supremely confident mind to propose. Einstein, age 26, saw light as both waves and particles, picking the attribute he needed to confront each problem in turn. One thing behaved in two ways. Einstein wasn't finished yet. Later in 1905 came an extension of special relativity in which Einstein proved that energy and matter are linked in the most famous relationship in physics: E=mc2. (The energy content of a body is equal to the mass of the body times the speed of light squared). Here, mass and energy is the same thing, they are dual.
Then In 1907, Einstein confronted the problem of gravitation. Einstein began his work with one crucial insight: gravity and acceleration are equivalent, two facets of the same phenomenon. Two things can be treated identically. They share a duality.
There is a new duality that is emerging that is central to LENR. It seems the superconductivity and black holes behave in the same way and can be described by the same mathematics and demonstrate the same behavior.
Superconductivity is critical in the characterization of LENR. It provides some of the miracles that LENR demonstrates. This is due to the dualism that superconductivity shares with black holes. A superconductive Bose condensate is an effective black hole. The BEC acts like a black hole.
To justify this concept, I offer these two papers from the top man in black hole theory: Gary Horowitz. Prof Horowitz explains in some detail how superconductor/black hole dualism works.

Using general relativity to study superconductivity
BEC/Black hole dualism is a solid and universally accepted concept in science and has been demonstrated experimentally.
Horowitz shows in the GR presentation how general relativity theory and associated math can be used in superconductivity and therefore LENR to show how LENR works.
