Quantum Mechanics does not explain the three most mysterious phenomena.
1) Single Particle Interference. (2) Correlations between particles that are separated by arbitrarily large distances. (3) Presence or tunneling of particles in classically forbidden regions.
Quantum Mechanics is inconsistent
Quantum Mechanics assumes a collapse of the wavefunction upon a measurement. However, the wavefunction’s unitary evolution is inconsistent with the nonlinear collapse.
Wavefunction can spread over arbitrarily large distances. However, experiments detect only localized whole particles. An extended wavefunction cannot collapse to a microscopically localized particle instantly.
Linear superposition encodes multiple particle states in a single wavefunction. However, experiments detect only a single particle. Empty states disappear after a measurement. Quantum Mechanics does not explain why and how they are there or how they disappear.
Quantum Mechanics suggests that (1) Einstein’s spooky-action-at-distance is real and (2) nature can communicate at superluminal speeds, but humans cannot. Laws of nature cannot depend on the existence of humans or their conscience. Multiple norms of applicability contradict the essence of science.
The uncertainty principle prohibits simultaneous measurement of the speed and location of a particle. Quantum Mechanics implies that uncertainty is an inherent aspect of nature, and we will never be able to measure momentum and position with better precision. A fundamental limit to our ability to understand nature contradicts the history of science.
