This paper considers the assumption that Planck time and length values increase in gravitational wells, an effect that becomes more extreme in a black hole event horizon. Obviously, this assumption considers the point of view of an observer who is far from the gravity well, as opposed to an observer in the well, will not feel the effects predicted by the Schwarzschild equation. Whereas the values of these Planck constants remain unchanged for the observer in the well.If physicists can accept that the Schwarzschild equation describes effects that are applicable to Planck time and Planck length, they will see that in a black hole´s event horizon the value of Planck length grows to the size of the event horizon. Thus, in terms of Planck length, every black hole (no matter its mass) has an event horizon radius that is always the same size, which is equal to one Planck length.These authors believes that these considerations are fundamental in the development of a new theory that can effectively unite quantum mechanics with general relativity. The first step in this direction is to break the basic paradigm that considers that Planck constant values (Planck time and Planck length) are always constant, regardless of the location of the observer, which comes into direct confrontation with the Schwarzschild equation. Keeping in mind that the time dilatation and space shrink effects, given by the Schwarzschild equation, depend on the observer´s position.
