Quantum mechanics proves that quantum mechanics is valid.

It is the mostly widely accepted interpretation but it is not the only one.

We’ve been confident before and spent centuries chasing literal ether.

The Copenhagen interpretation is just that, an interpretation.

We’ve chased it for decades and are no closer to resolving it with classical mechanics.

I’m sure future scientists to scoff our demand that there be an “observer”

It still cannot account for gravity.

The formulas pretend it doesn’t exist. It reminds me of a physicals 101 class pretending friction doesn’t exist.

Friction exists and so does gravity, therefore they are both pretend.
