Difference Between Hypothesis And Theory

What is a Theory? 

A theory is a rational and contemplative type of conceptual thinking about a phenomenon or the results of such reasoning. The process of reflective and analytical thinking often is connected with methods like research or observational study. Theories may either be scientific or less to the extent to become scientific. For example, incorporate generalized information about how nature works, depending on the context. The term "Theory" has its origins in ancient Greek, but in everyday use, it has taken on several related meanings.

The theory is executed by assembling a large amount of data from different sources and examined individually and collectively to bring forth as several facts as possible. The theory is derived continuously in the end after all the tests are completed, and the research comes to one ultimate completion. The authenticity and efficacy of a theory are substantial, as it is supported by evidence of the proof that has been obtained through extensive research. A theory is generated through the details present in the existing circumstances.

Difference Between Theory and Law

The scientific method is devised and coordinated or logical way of discovering answers to questions or uncovering solutions to problems.One of the essential steps in the scientific method is formulating laws or theorising based on the experimental outcome.

Both theory and law should be rational, logical, scientifically testable concluded with existing experimental or observational proof. Valid scientific laws are more valuable than actual scientific theories. Theories explain how nature works and law explains whatever nature is doing under certain conditions. 

Difference Between Theory and Model

The descriptions of theory and model can be complicated. Learners may come up with both theories and models, after completing the step-by-step method of the scientific process; however, models and theories are presented in different stages and levels of the research. 

Models may be provided after the formulation of theories, but there can be situations where the models are assembled before the theories. There can also be instances when models create theories that in return, lead to the formation of another model for the confirmation of a theory.

What is the Hypothesis? 

A hypothesis is a suggested specification for a phenomenon. For a theory to be a scientific hypothesis, the scientific process demands that one can test it. Scientists usually base scientific assumptions on previous observations that cannot adequately be defined with the possible scientific theories. 

Even though the words "hypothesis" and "theory" are commonly used synonymously, a scientific hypothesis is not the equivalent as a scientific theory. 

A twitching hypothesis is a temporarily accepted hypothesis recommended for further research, in a method commencing with an educated opinion or idea. A hypothesis is a claim that can be tested or made and has falsifiability.

Theory vs Hypothesis

A hypothesis suggests an interim analysis or foresight. A scientist bases their hypothesis on an actual event, making an educated guess as to how or why that event happens. Their hypothesis may be demonstrated as true or false by experimentation and testing. A theory, on the other hand, is a confirmed information for an incident. Theories rely on certified and validated data, and scientists generally accepted theories to be accurate, though not irreproachable.

Let us glance at the difference between hypothesis and theory presented in a tabular column below.



A theory describes a natural phenomenon that is validated through observation and experimentation.

A hypothesis is an educated assumption based on specific data that serves as a basis for further investigation.

Theory is based on extensive data    

Hypothesis is based on limited data

Scientifically proven and tested is a theory

Scientifically not proven is Hypothesis

In a theory the results are certain    

In a hypothesis results are uncertain    

Theory relies on proof and verification 

Hypothesis relies on the probability

A theory is the verification of a common principle through experiments and multiple tests, and this system may apply to different explicit situations.

The Hypothesis is usually based on meticulous research and is limited to that instance.

FAQs on Difference Between Hypothesis And Theory

Q1. Define the Three Examples of Scientific Theories?

Answer: The three examples of Scientific Theories are : 

  • The Big Bang Theory: demands that the universe began as a small singularity 13.8 billion years ago and extended suddenly.

  • The Heliocentric Theory: Nicolaus Copernicus' theory illustrates that Earth travels around the Sun.

  • The Theory of General Relativity: Albert Einstein's theory claims that large objects (like the Earth) create a malformation in space-time, which is encountered as gravity. This theory replaced one of the most famous scientific laws, Newton's Law of Universal Gravitation.

 Q2. Define the Term Law.

Answer: Scientific laws are sweet, short and always accurate. They’re often displayed in an individual assertion and usually rely on a brief mathematical equation. Laws are affirmed as universal and are the support pillars of science, they can never be wrong, and for this reason, there are many theories but few laws. If a law is proved to be false, any science produced on that law would also be wrong. A scientific law is also known as the laws of nature. Some of the examples of scientific laws involve the thermodynamics law, the laws of gravitation and Boyle’s law of gasses.
