Final answer:
Johannes Kepler asserted that there is a fundamental set of physical laws that govern the universe.
Step-by-step explanation:
The idea of a fundamental set of physical laws that govern the universe was asserted by Johannes Kepler. Kepler, a German astronomer, believed that the true model of the universe could be understood through mathematics and discovered three laws of planetary motion that explained how the planets moved in the heliocentric model of the universe. His belief in the power of mathematics to explain the physical world was shared by other scientists of his time, including Galileo Galilei.
The concept of a unified set of physical laws is consistent with the findings of modern physics. Physicists have discovered that a small set of fundamental laws can explain a wide range of phenomena in the universe. This idea has been further developed and refined by other scientists, such as Isaac Newton, who presented a comprehensive model of the workings of the universe based on scientific principles.
