What two things must a theory do?

A theory must provide an explanation for an observation and be reinforced by observational data and experimentation.


What will not be valid with scientific theory?

Personal opinions, beliefs, or anecdotes that are not supported by empirical evidence will not be considered valid within a scientific theory. Theories must be testable, falsifiable, and based on systematic observation and data analysis. Emotional reasoning or cultural bias should also not influence the development or acceptance of a scientific theory.

What conditions must be satisfied for a scientific theory to be valid?

One of the conditions that must be satisfied is that it must match the evidence that is provided. Next it should be able to predict things. Lastly, it's statement must be able to be verified independently.

How do you define theory?

In the general, every day sense of the word a theory is a supposition, a hunch or a speculation. It is unproven.A Scientific Theory is completely different from an every day theory. A scientific theory summarizes a hypothesis that has been supported with repeated testing and with facts that can be observed and/or measured. With that support a hypothesis moves to the next step in the scientific method and becomes accepted as a valid explanation of a phenomenon. Facts are the framework for the scientific method and a Scientific Theory is supported by facts.


How is the validity of scientic theory tested?

Scientific Theory is tested by observations and experiments predicted by the theory. If the observations confirm the theory the theory is validated if not the theory is not validated. Experiments themselves need validation, often there are errors in the experiments or observations, e.g Michaelson and Morley Aether experiment and red shift observations.


What is a scientic theory?

A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. If enough evidence accumulates to support a hypothesis, it moves to the next step; known as a theory; in the scientific method and becomes accepted as a valid explanation of a phenomenon.


When must a scientific theory be changed?

Whenever new data shows that its wrong.
