Wavefunction; The Guided Energy of Wave

This paper expound the true nature of wavefunction and answered questions that arise from quantum foundation such as what is nature of wavefunction? Is mathematical formalism of wavefunction correct? Does wavefunction collapse during measurement? Do quantum physical entanglement and many world interpretations really exist? In addition, is there uncertainty in the physical reality of our nature as being concluded in the quantum foundation? The fundamental analysis presented in this work show that mathematical formalism of wavefunction was wrongly formulated. Because, we discovered that, wavefunction is the guided energy of wave by the reason that the universe and everything in it from large particle to the smallest tiny particle, physical and imaginary, visible and invisible, existing and non-existing has guided energy which is wavefunction.We further show that wavefunction is not collapse, only disengaged and engaged gradually. The gradual process of wavefunction disengagement display how the particle-like behavior return to wave-like behavior and the gradual process of wavefunction engagement also display how wave-like behavior return to the particle-like behavior. Convergence and divergence of wavefunction exhibit precise position of a particle and wave amplitude respectively.
