to observe a 1000year process in just one day
A scientist formulates a hypothesis or an educated guess, then researches the hypothesis and designs a controlled experiment or a series of controlled experiments to test the hypothesis. Then on the basis of experimentation, the researcher formulates a conclusion or solution of the problem.
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.

Scientists repeat their experiments because to make sure that their results are correct.

you might not get the experiment correct (:
Variables
because your adopted. nawh just kidding, but seriously one reason why a controlled experiment may not be possible is because...ok lets say you had an experiment of a cancer-causing chemical, they might exclude volunteers who have other serious health problems. by exerting great care in planning these kinds of investigations, scientists can discover reliable patters that add to scientific knowledge.
The reason they would is because it is a lot safer.
