This is an essay on solving the issues concerning the Wheeler-deWitt equation and the main implication that is used to denote the many-worlds interpretation.  I will show that the issue lies in the interpretation of the equation itself, and can be solved by merely changing the perspective of the subject.


Wheeler-deWitt Equation

Problem:

This equation represents the solution to the wavefunction of the universe.  The answer to many scientists' protest is zero.  The reason for such protest is due to the fact that this solution means that there is no time evolution in our universe.  This means that time does not flow, but this contradicts observation (obviously).  We observe our universe with time, and we are not frozen in time.

Solution:

This can be solved by merely changing the viewpiont of the equation.  This equation describes the solution to the wave function.  However, the wavefunction is only present to an outside observer, and is in a seemingly collapsed state to an observer within the system.  This means that this zero time evolution only applies for observers outside the universe, but within time evolution is preserved.  The equation describes the wave function, not the collapsed state, and therefore does not divulge what is occuring within the system.

Conclussion:

Time evolution is preserved by taking into account that the solution represents only what is seen by an outside observer, and not an observer within the system.  Therefore, time evolution is preserved, and the problem is solved.
