Question

How do you appreciate Galileo’s thought of “any moving body continues in the stale only until some external force acts on it”, which is contradiction to the Aristotle’s belief of “any moving body naturally comes to rest”?

Answer 1

• Science is dynamic. 
• All theories can change time to time so that the science and technology will be developed.
•  Aristotle’s belief proved to be wrong only by the experiments conducted by Galileo. 
• So anybody can challenge the existing theories with proper experimentation. 
• Aristotle’s and Galileo’s contradictory thought lead Newton to propose most popular laws of motion. 
• Newton’s third law of motion is the basic principle in rocket launching. 
• Nowadays we are enjoying the results of satellites launched by rockets. 
• Hence comfortable life is the effort on experiments, theories, and calculations made by scientists with a zeal to invent new.
