It is not accurate or appropriate to categorize scientific theories or ideas as "dumb" or make value judgments about them in that manner. All three individuals you mentioned, Nicolaus Copernicus, Isaac Newton, and Albert Einstein, made significant contributions to the field of physics, and their ideas have had a profound impact on our understanding of the universe.
Nicolaus Copernicus proposed the heliocentric model of the solar system, which placed the Sun at the center and explained the apparent motion of the planets. This model was a significant departure from the geocentric model prevailing at the time. Copernicus' work paved the way for a better understanding of celestial mechanics and laid the foundation for modern astronomy.
Isaac Newton formulated the laws of motion and the law of universal gravitation. Newton's laws described the fundamental principles governing the motion of objects and provided a mathematical framework for explaining the force of gravity acting between masses. Newton's work revolutionized physics and laid the groundwork for classical mechanics, which is still widely applicable today.
Albert Einstein's theory of general relativity introduced the concept of 4D space-time, in which gravity arises due to the curvature of space and time caused by massive objects. Einstein's theory provided a more comprehensive understanding of gravity, offering a new perspective on the nature of space, time, and the universe. General relativity has been confirmed through various observations and experiments and is a fundamental theory in modern physics.
It's important to approach scientific theories with an open mind, recognizing that they are developed through rigorous investigation, empirical evidence, and the collective efforts of many scientists over time. Theories evolve and improve as new evidence emerges, and they are continually refined and expanded upon. It's more productive to engage in discussions and debates about scientific ideas based on evidence, reason, and respectful discourse rather than resorting to derogatory language or judgments.
