Well, I'm saying that science is the only way to get knowledge that is objective. (won't change depending on who seeks the knowledge)
What you mean by objective?
Thus making the scientific method, the only way, that I know of, for an individual to determine the accuracy of a claim.
A claim? Like any claim? Or just "objective" claims?
You clearly are confusing the restrict scientific method with general philosophy.
Philosophy is the only human activity that can verify any claim.
In fact the scientific method is philosophy applied to the physical world.
Additionally, I would argue your assertion that the scientific method can only be applied to the physical world is flawed.
So you don't understand the scientific method. The scientific method is only applicable to the physical world.
After all the scientific method is simply a question to which someone applies systematic observation, measurement, and experimentation and then formulates, tests, and modifies a hypothesis to that question.
Right.
In principle, the scientific method can be applied to study things that aren't directly perceivable, energy for example.
Energy is physical.
I will grant that the scientific method is better with some subjects than it is with other subjects, and there are some questions it can't answer,
There are subjects that the scientific method is not applicable at all.
but anything that has an impact on the physical world can be measured, and directly or indirectly observed.
This is positivism. How do you scientifically measure the potential of an idea before it's execution? Even dreams have an impact on the physical world.
The scientific method says nothing about it being a universal tool. Giving the universal application to it is a positivist idea (which is a metaphysical assertion BTW).
The scientific method only was possible inside the Abrahamic tradition (especially Christianity, thank you William of Ockham). Actually the scientific method was born entirely inside the Abrahamic tradition, you can't change this fact. Because it was the only system that didn't consider the physical world as equal to God (like Chaos in Greek mythology). Any other philosophical system considered the physical world being a god, or a limb of a god, etc. In this worldview you don't study the physical world but you worship it just like every pagan really did.
