People used to think that blood could flow in any direction in the veins. William Harvey came up with evidence used to show that blood moved only in one direction through veins. He discovered that the valves in the veins permit blood to flow in one direction only. He said that blood circulates in only one direction through the body and returns to the heart.
Einstein developed the theory of mass-energy equivalence, which is famously expressed as E=mc^2. This breakthrough was part of his theory of relativity and fundamentally changed our understanding of the relationship between mass and energy.
William Harvey first proposed the theory of blood circulation in his work "De Motu Cordis" published in 1628. Harvey's theory was subsequently supported by anatomical and physiological evidence gathered through his experiments and observations, which helped validate and establish the concept within the scientific community.
The theory of continental drift has changed over time. Initially proposed by Alfred Wegener in the early 20th century, it was met with skepticism. However, over the years with advancements in technology and research, the theory evolved into plate tectonics, which is widely accepted today.
The Theory of Special Relativity was published in 1905. General Relativity was published in 1915.
Albert Einstein was best known for his Theory of Relativity, which consists of two parts: the Special Theory of Relativity, published in 1905, and the General Theory of Relativity, published in 1915. These theories fundamentally changed our understanding of space, time, and gravity.

Atoms may not be changed into other atoms.
The theory of blood circulation changed significantly with the publication of William Harvey's book "De Motu Cordis" in 1628. Harvey proposed that blood circulates continuously around the body in a closed system, propelled by the heart. This replaced the older theory of blood being consumed by the body, and laid the foundation for modern understanding of the circulatory system.
The blood circulation in the Lungs, called the pulmonary circulation, is COMPLETELY a part of the general, systemic circulation of Blood.
The statement that all organisms were created in their current form and have not changed over time is not part of the modern theory of evolution. Evolutionary theory explains that organisms have changed and diversified over time through processes like natural selection and genetic variation.

science
whenever an experiment fails to confirm the theory it is no longer a theory ... it becomes a hypothesis
Yes, a scientific theory can be rejected if new evidence or observations contradict its predictions or if a more accurate theory is developed. The rejection of a theory is an essential part of the scientific process that helps refine our understanding of the natural world.
larger quantity of money in circulation
Galen's theory about blood circulation was based on the idea that blood was continuously produced in the liver, then absorbed by the body's tissues, and eventually consumed or used up. He did not have a correct understanding of the circulation system as we know it today, but his theories dominated Western medicine for over a thousand years.
