Question

After completing 10 years of experimentation, a scientist reports a new scientific law about the movement of sand on beaches. How do you know that this information cannot be valid?

Answer 1

Answer:

there are no previous laws to substantiate the information.

Explanation:

Scientific laws build upon each other. In other words, the laws complement each other. For instance, there are laws that are known as the fundamental laws. These laws lay down the foundation of all scientific beliefs and hypotheses. Without a satisfaction of these laws, the research will be null and void. In fact, it will be invalid unless the first principles of the physical laws are satisfied and proved.

Answer 2

Scientific laws are not proven, rather they are assumed to be true by the results of other experiments. Basically, this scientist is saying that he has proven a scientific law, which is not possible. He most likely has proven a scientific theory if he has proven something.
Hope that helps!
