You don't even know what a Planck length or time is. It's the only natural combination of G, h and c which give units of length and time. They aren't theories, they are new units of length and time. It's equivalent to you saying "Anyone who works in imperial units is wrong, you should work in metric units!" as if the answer "The distance is 30 centimeters" is more correct than "It's 12 inches".
Sorry I wasn't clear. Plank had doubts about the constant h which is used to derive his length and time units. Plank constant is used to calculate the energy of a photon (E=hf) of "visible" light. What about invisible light as it pertains to gravity as described in my book and theories. In my theory, all measurable "electromagnetic" light falls under a specific range of light frequency and "amplitude" which travel "roughly" around the speed of light (c). Together frequency and amplitude of light "vibration" in space-time substance would trully express the energy of that space-time vibration (photon). Current physics does not account for space-time vibrations (photons) of very low frequency and large amplitude or high frequency and very low amplitude. Current physics "locks" photons into it's own category and negates any relationship between a photon and say a ripple running through water. This locking of space-time vibration (space-time vibration is itself a theory too just to be clear) in current physics is assisted by Plank constant h. This "locking" of our understanding of light is wrong. We shouldn't be "blindly locking" natural effects we still don't truly understand by using constants. We should understand that constants are place holders for the true reason behind the effect. To truly understand the physics, in my opinion, Plank's constant has to be removed completely.
