Here is a hypothesis: QM probability shouldn't be written for 2d/3d spaces but 0d space using Pascal's Triangle
*note this would be useful in calculating Wavefunctions that last less than maybe 100,000 Planck lengths of time*
One trait of a Wavefunction (either position or momentum) would now be 2 Planck constants, in other words, the first row of Pascal's Triangle: 1 + 1 = 2 and how that trait changes over 1 Planck time is calculated as the 2nd row of the triangle, and so on for the 3rd, 4th and any number of rows.
This way, a Wavefunction no longer has infinite states before measurement because the act of measurement is no longer needed. You now only need a Pascal's Triangle to describe a finite amount possibilities for a single trait of a Wavefunction, and once you have a finite amount of possibilities listed for say position, you now just calculate each of those (position)possibilities with a new Pascal's Triangle representing the accompanying momentum, basically getting every possible position and speed combination there is for a short enough Wavefunction.
Not sure where this would be useful, since even the world's smallest double slit experiment takes 247 Zeptoseconds
