In a carefully designed experiment, the reorganization of the environment will give new or previously unrecognized knowledge about something. So therefore an experiment, or science, is merely changing one's viewpoint to allow the human brain to accept or realize information through specific sensory neural pathways. As such, they are for the most part inseparable, both being abstract and inevitable processes of the mind. I think that we can't separete ethics question from science, because we don't find a science real and general ethic. This situation made the world what he is today, we are just loking for a science general ethic, without one we might have a unethic world.
Science is a branch of study concerned with facts, principles, and methods.
However, ethics is the moral science that governs what we do with it. It is the branch of philosophy that studies the principles of right and wrong in human conduct. The question of their individuality has been in existence for quite some time. I would argue that in theory they can exist separately but in practice they cannot. In Aristotle's structure of the soul, one can see that science takes precedence over ethics.
