My theory runs as follows:
Take two partcles, and measure the energy found in both if them and the space between them. It is my speculation that as they get closer, the energy in the space between them raises. It follows that with higher energy in a smaller area, the curvatureof spacetime would be warped, explaining the differance in expected values between quantum and relativity.
Basically im saying an oversight caused a math error.
I am not a quantum physicist and i only study it as a hobby, this is almost definitely not the actual solution
