>We can not measure the particle/ wave without changing the outcome.

I thought about this and came up with the idea that theoretically you could detect the gravitational wave(GW) emitted by the passing particle without manipulating the outcome. The GW would give you information about the position and velocity of the particle and therefore eliminating the quantum mechanical probabilistic nature.
This would make the double-slit experiment, and maybe any other quantum mechanical phenomena, deterministic.

Ignoring the technical feasibility of detecting GW of single particles, where did I go wrong?
