Many branches of science do not lend themselves to experiments. Cosmology or astrophysics are subjects where it is extremely difficult to conduct experiments. Theories are developed though thought experiments which are then used to make testable predictions. It is only at the later stage that experiments enter the picture.

Controls are required to have at least one group for comparison in an experiment. Typically, there is one control group that does not receive the treatment being tested, allowing researchers to compare the results of the treatment group to the control group.
