On the Possible Zero Value of the Spatial Curvature Constant

Authors: Fernando Salmon Iza

The value of curvature k that appears in the Friedman's equation of the FLRW metric is the subject of controversy. Of its three possible values (+1, -1, 0), determining whether it is zero or not is an important problem in physics. The experimental results existing today do not allow us to resolve it. In this report we have studied this problem by carrying out a theoretical calculation of the parameters, curvature density Ωk and matter density Ωm. To do this we have obtained an equation that relates the spatial curvature constant to the energy density and through it and the Friedman's equation we have calculated Ωk and Ωm. The ratio between the two will determine whether the curvature k is zero or non-zero. The result obtained in this report leads us to think that the curvature constant that appears in the Friedman's equation is zero.
