The scientific method is the study of matter.
What? What?!!
Did you even read the paragraph you cited?
The scientific method isn't only the study of matter. At all.
To accurately summarize the paragraph you cited- the scientific method is concerned with gaining new knowledge and correcting old knowledge through evidence and reasoning.
So please explain to me how the scientific method is able to measure that which does not exist as matter or energy?
Dark Matter and Dark energy, please explain how that is measured with scientific instruments or observations?
I suggest you actually try a new method in your reasoning. Instead of being in opposition to whatever I say, which is a serious flaw in learning, try understanding what I am attempting to convey.
I could point out, that in your entire life, you have been so conditioned and brainwashed to do that when someone questions your current State sanctioned rubber stamped approved reality that it becomes a knee jerk reaction that is done at an unconscious level.
My goal here is not to talk to a parrot, but to reason with another individual that is capable of expanding your horizons beyond beliefs or institutional conditioning.
Dark energy is the most accepted hypothesis
It can't be seen or it can't be measured.
It is theoretical.
If more than 95% of matter in the universe is not considered in the scientific method, than the reality that exists that science deals with is less than 5%.
Studying less than 5% of what is, and proclaiming to be the machine of truth would be a serious flaw in Truth.
If it is your standpoint that studying less than 5% of the universe by a method is not flawed, than I would classify that as a statement of a narrow mind.
For example, most human beings even though they walk around conscious, have little consideration for what exactly consciousness is and how it occurs.
But in conclusion, the scientific method is flawed because it only studies what exists in our physical universe and by that it must contain mater or energy.
However it is already a consideration by theorist, that all the matter and energy in the universe that we can observe through the scientific method is less than 5%.
I would not trust any map in which the whole map was based on only knowing 5% of the actual information.
Would you?
