The article under reviewing by its spectra of problems put into discussion try to represent a very actual research. The topics includes also dark energy, negative black holes pressure (recently discussed by Xavier Calmet and Folkert Kuiper), naked singularities and causality principle, tachions. For this the authors modify the Heisenberg’s Uncertainty principle( HUP), into the so called Generalized Uncertainty principle (GUP). Similar modifications were predicted previously by J. Magueijo and L. Smolin in [“String theories with deformed energy-momentum relations, and a possible nontachyonic bosonic string”, Phys. Rev D 71, No. 2, Article ID 026010, 6 p. (2005; doi:10.1103/PhysRevD.71.026010)] which were concretized by authors by the Linear and Quadratic Generalized Uncertainty Principle ( LQGUP). Being provoqued by new findings in a series of previous papers by authors of the actual paper and by the existence of massless charged particle and of a naked singularity in a Reissner-Nordstrom-de Sitter solution with a null mass ( massless RNDS solution), the authors are interested now in studying tunneling phenomena through the cosmological horizon of the RNDS spacetime. The authors mention the connection between massless black holes and tachionic fields. As an argument to application of this approach to massless supersymmetric black holes (diholes) serves the unaplicabillity of the Penrose’s cosmic censorship principle to microscopic objects. The authors concludes, that massless Reissner-Nordstrom-De-Sitter metric in the the context of minimal length scenarios might be interacting with Dirac sea and in this case they will appear outside of the cosmological horizon in the context of DS/CFT holography. The main conclussion of the authors is that a spacetime Big Crunch may occur. The article contains a number of pictures illustrating tunneling of bosonic and fermionic massless fields. Reviewer is mentioning that some of concepts authors refer to in the article ( such as tachions, naked singularities ) have a much older history in the literature than the authors cite at the finish of the article.
