Starting from a simple, one-parameter, symmetric wave function, we derive an attractive double Dirac delta potential with a centrifugal, angular-momentum-like tale, which has only one bound state, the energy of which can be set to zero.

This article discards the constant Planck-energy. This will be in service of a rotating vacuum-torus as a new building-stone in a variable vacuum for the benefit of a rotating hologram-universe. The new building-stone hosts all the sub-information for the quantum-information for each emerging not-fundamental Big Bang-universe. This leads to the presentation of a new formula for dimensional variable dark energy. Also a handwritten image shows the author’s velocity-tensor of rotating vacuum, which is combined with an energy of dark force emerged from a dark vacuum particle. He uses his tensor to explain the name of his theory, the Double Torus Theory (DTT) .

The Schrödinger eigenvalue problem with the purely exponential potential is investigated in this work. It is shown that exact and explicit discrete bound state solutions with negative eigenvalues may be computed for the attrative potential as well as for the repulsive potential in terms of elementary functions.

Development of the mathematical model of the elastic universe. The energy of the loks (3.0), (3.1), (3.2), and (3.3) is calculated. Assumptions are made regarding other loks. The first conclusions on the identification of elementary particles in a set of loks.

Newton's mechanics is simple. His equivalence principle is simple, as is the inverse square law of gravitational force. A simple theory should have simple solutions to simple models. A system of n particles, given their initial speed and positions along with their masses, is such a simple model. Yet, solving for n>2 is not simple. This paper discusses, why that is a difficult problem and what could be done to get around that problem.
