why are controlled experiments sometimes impossible?
the reason it is important to controll the variables in an experiment is because if the variables are not controlled in an experiment it will be impossible to reproduce the experiment. which also will make it impossible to prove the theory being tested
The hypothesis states what question you are studying. If there is no hypothesis, one wouldn't know what one is studying, so it's impossible to construct a controlled experiment.
sometimes it is because you might not know what is going to happen.

A controlled experiment might be impossible if there are too many variables that cannot be controlled or if it is unethical or impractical to manipulate certain variables. Additionally, external factors outside of the researchers' control can also make it difficult to ensure a controlled environment for the experiment.

It is impossible to perform controlled experiments on phenomena that are unpredictable, uncontrollable, or unethical to manipulate. For example, certain natural disasters, historical events, or intentional harm to individuals cannot be ethically or practically studied through controlled experiments.
A controlled experiment is better than a none controlled experiment because you can control one of them and the other you can't. Science is a really fun subject.
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group.
a controlled group is like an idea but an experiment that is controlled cannot be changed.
