Many philosophers believe that our world can only be described accurately using mathematical equations. Mathematical equations allow a strictly defined interpretation that can serve as a reflection, or picture, of reality in the Universe, and it is supposed that this is the only possible and allowed view of our world. However, it is possible to find mathematical equations that allow the calculation of certain numerical values related to our physical world, not found, however, in physics or astrophysics books. These equations presumably allow for a new different interpretation of the reality of our Universe. But what should we think about it, if a single property, e.g. the gravitational force, could be calculated using different mathematical equations? Here a mathematical formula is presented from which it is possible to calculate the energy density of solar radiation on the surface of the Sun and thus the total power of the Sun and this without using the Solar Constant. There is as yet no theoretical model describing any physical phenomena from which this formula would follow. One possible conclusion from this formula is that physical constants like the Proton mass or the Gravitational Constant are not constants in the Universe and are not even constants in the Milky Way galaxy in which the Sun is located. I assume that the mathematical formulae presented here are understandable to most people interested in physics. At the same time it is one of the following three works "A Different Look at the Power of the Sun, "A Different Look at the Hydrogen Atom" and "A Different Look at Gravity" allowing to explain, with the help of simple mathematical equations of classical physics, the reality in our Universe more simply and comprehensibly, assuming that new models of physical phenomena will arise, from which the mathematical solutions presented here result.
