There are many sound scientific theories that physicists choose to ignore in order to make their science cleaner and more tidy. Instead of expanding science by pursuing new ideas, they pretend that certain phenomena don’t exist. A proven theory should not be shunned and ignored in the name of simplicity.
The existence of Zero Point Energy, for example, is not contested in scientific circles, yet scientists generally ignore it in the mathematical equations that describe three dimensional reality. Zero Point Energy does not fit into linear equations, but when Quantum Mechanical math is used, it ties in beautifully, with elegance, harmony and grace.
