Question

What determines the validity of a theory?

a) The popularity of the theory
b) The number of equations in the theory
c) The ability of the theory to predict and explain observations
d) The length of time the theory has existed

Answer 1

The validity of a theory is determined by its ability to predict and explain observations.

Step-by-step explanation:

The validity of a theory is determined by its ability to predict and explain observations. It is not determined by the popularity of the theory, the number of equations in the theory, or the length of time it has existed.

For example, let's consider Newton's theory of gravity. This theory has been widely accepted for centuries because it successfully predicts and explains the motion of objects on Earth and in space. However, the theory of gravity proposed by Einstein, known as general relativity, provides a more accurate explanation of gravity in extreme conditions such as near black holes.

Therefore, the validity of a theory is based on its empirical support and its ability to stand up to rigorous testing and observation.
