I would not say so, quantum physics and Relativity are both physical theories with strong experimental proof in their own domains, very small scales and very big scales. They are both extremely higher on the scale of trustworthy believes than any religion could be. I think most physicists believe quantum physics has solider proof than Relativity thanks to the enormous statistics from experiments that we can control like the LHC. For (General) Relativity, we kind of have to do with what the universe sends us.
They are both systems of beliefs, like religions are, but with a much higher level of proof, so physicists have some skeptical faith in both of those theories.

But even tested to the most extreme limits, it takes faith to even believe in the highest and most true results of scientific method.

So really it just boils down to how you use your time.

Much like a quarter in an arcade machine; from the 'Simpsons: Arcade Edition' times of lore.

Newton's laws were established science for centuries and they were proven to be not as good as Relativity some centuries later. Given that there is some incompatibility between quantum physics and Relativity, and the dark energy/matter mystery, it is likely that the current physics theories are also not completely correct. Even if we solve that, verification will always be limited to a certain degree of precision. So we will never be able to prove that a theory is fully correct, we can only try to prove that it is wrong indefinitely. But we can have a rational belief based on their degree of verification and make bridges, computers and medicine with them.

It requires belief in proven results. Those who are unwilling to learn won't learn, and there is nothing that can be done to change this.

Our understanding of it does, because that is how we choose to interprit the printed rules we think the universe is governed by.

How the universe actually works is anyones guess, but we can make an educated and informed attempt.
