The Scientific method and its role in Astronomy

The scientific method is a research concept that was born along with the first foundations of modern science at some point during the 1600-1700s. It comprises a series of steps believed to be necessary in order to properly carry out a scientific discovery or theory.

Modern science and the scientific method are both based on empiricism: the idea that humans can only reach knowledge through experimentation, observation, and the data received by our senses.

The scientific method is a very general guideline that gives the scientific community an idea of how to develop accurate explanations for the behavior of the universe.

Through the development of his own magnifying telescopes, the Italian astronomer Galileo Galilei confirmed Copernicus's theory roughly 70 years after its formulation. He also accomplished this based on experimentation, on a combination of mathematical predictions and repeated observations of celestial bodies in our Solar System.

Isaac Newton finished polishing this new understanding of our universe thanks to his discoveries of gravitational forces, the properties of light and the principles of motion, something Galileo had also been working on. With these contributions, astronomy was completely reinvented.

So thanks to those three geniuses and several others, modern astronomy was born. And thanks to them, many of the foundations that compose the scientific method were also born.
