What scientific theory is no longer accepted?
Miasma theory of disease – the theory that diseases are caused by "bad air". No experimental support, and rendered obsolete by the germ theory of disease. Phrenology – a theory of highly localised brain function popular in 19th century medicine.
What is an example of a scientific idea from the past that has been changed?
The idea of a luminiferous aether was debunked as experiments in the diffraction and refraction of light, and later Einstein's special theory of relativity, came along and entirely revolutionized physics.
What is a famous theory?
Big Bang Theory. Hubble's Law of Cosmic Expansion. Kepler's Laws of Planetary Motion. Universal Law of Gravitation. Newton's Laws of Motion.
What is the most successful scientific theory?
Quantum mechanics is perhaps the most successful theory ever formulated. For almost 90 years, experimenters have subjected it to rigorous tests, none of which has called its foundations into question. It is one of the triumphs of twentieth-century science.

What are examples of scientific theory?
A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Examples of theories in physical science include Dalton's atomic theory, Einstein's theory of gravity, and the kinetic theory of matter.
What is scientific theory?
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.
What was the most important scientific breakthrough of the past 300 years?
Penicillin. Alexander Fleming discovered penicillin in 1928.
What was believed before the scientific revolution?
Previous to the scientific revolution, science regarding the placement of Earth in the universe was restricted by views held by the heavily religious society. The common held belief for a long time was that the Earth was the centre of the universe and that all the planets revolved around it.

What is the most famous theory?
Albert Einstein's theory of general relativity has held up pretty well after a century out in the world. The famous theory, which Einstein published in 1915, remains the bedrock upon which scientists' understanding of the origin and evolution of the universe rests.
What is the most accepted theory?
Throughout history, countless myths and scientific theories have tried to explain the universe's origins. The most widely accepted explanation is the big bang theory.
What are two scientific theories?
Some theories are so well-established that they are unlikely ever to be fundamentally changed (for example, scientific theories such as evolution, heliocentric theory, cell theory, theory of plate tectonics, germ theory of disease, etc.).
Which is an example of a scientific theory?
A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Examples of theories in physical science include Dalton's atomic theory, Einstein's theory of gravity, and the kinetic theory of matter.

What were the ideas of the Scientific Revolution?
The Scientific Revolution was characterized by an emphasis on abstract reasoning, quantitative thought, an understanding of how nature works, the view of nature as a machine, and the development of an experimental scientific method.
What is Scientific Revolution in history?
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
What is the accepted theory?

What is meant by Scientific Revolution?
Definition: In very generic terms, scientific revolution refers to the resurrection of modern-day science. This can be said to have happened when developments in various branches of studies, especially in chemistry, physics, math, astrophysics and biology, completely transformed the way of doing many things.
What century was the scientific revolution?
The developments in science during the 16th and 17th centuries have traditionally been called the “Scientific Revolution.” The era that began with Nicolaus Copernicus (b. 1473–d. 1543) and ended with Isaac Newton (b. 1642–d.
What launched the era of modern science in the 17th century?
The era of modern science in the 17th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature's behavior.
How is scientific theory accepted?
See if this sounds familiar: Scientists begin with a hypothesis, which is sort of a guess of what might happen. When the scientists investigate the hypothesis, they follow a line of reasoning and eventually formulate a theory. Once a theory has been tested thoroughly and is accepted, it becomes a scientific law.
