Who knows what future physics holds (I’d love to know!) but our best theory of gravity (Einstein’s general relativity) is shown to be amazingly accurate in every experiment ever conducted for it.

Some form of only-detectable-via-gravity matter fits the math. Coming up with provable alternative math would be the greatest scientific breakthrough of the past century...or possibly of all time.

I’m sure people are working on it (along with quantum gravity). So either it’s wrong or it’s dark matter.
