Science is based on the principle of the inference to the most plausible. When you have multiple theories explaining a phenomenon, the one which makes the most sense with regards to the gathered data is deemed THE explanation. That is, until another theory comes with more compelling data and evidences.

Example: the "static universe" cosmological model

Science is basically our best understanding of the world. Doesn't mean it's 100% true, but it's how far we got.

Sure, but as an example, time being a constant whose rate doesn't change is a thing that'd make sense.. except it's completely wrong.

Turns out time is malleable and objects can experience it at different rates relative to each other, while keeping everything consistent.

Reality is weird and sometimes very counterintuitive.
