October Learn how and when to remove this template message Typically for any theory to be accepted within most academia there is one simple criterion. The essential criterion is that the theory must be observable and repeatable. The aforementioned criterion is essential to prevent fraud and perpetuate science itself.
The tectonic plates of the world were mapped in the second half of the 20th century. Plate tectonic theory successfully explains numerous observations about the Earth, including the distribution of earthquakes, mountains, continents, and oceans.
The defining characteristic of all scientific knowledge, including theories, is the ability to make falsifiable or testable predictions. The relevance and specificity of those predictions determine how potentially useful the theory is.
A would-be theory that makes no observable predictions is not a scientific theory at all. Predictions not sufficiently specific to be tested are similarly not useful. In both cases, the term "theory" is not applicable. A body of descriptions of knowledge can be called a theory if it fulfills the following criteria: It makes falsifiable predictions with consistent accuracy across a broad area of scientific inquiry such as mechanics.
It is well-supported by many independent strands of evidence, rather than a single foundation. It is consistent with preexisting experimental results and at least as accurate in its predictions as are any preexisting theories.
Other criteria[ edit ] In addition, scientists prefer to work with a theory that meets the following qualities: It can be subjected to minor adaptations to account for new data that do not fit it perfectly, as they are discovered, thus increasing its predictive capability over time. This is because for each accepted explanation of a phenomenon, there may be an extremely large, perhaps even incomprehensible, number of possible and more complex alternatives, because one can always burden failing explanations with ad hoc hypotheses to prevent them from being falsified; therefore, simpler theories are preferable to more complex ones because they are more testable.
The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them substantially.
For example, no new evidence will demonstrate that the Earth does not orbit around the sun heliocentric theoryor that living things are not made of cells cell theorythat matter is not composed of atoms, or that the surface of the Earth is not divided into solid plates that have moved over geological timescales the theory of plate tectonics One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed.
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.Science and Scientific Theories • Science is not a set of scientific theories – Science is like philosophy (in fact, science grew out of.

While true scientific research for the benefit of life on Earth must be supported, endeavors that have little scientific evidence to support their validity should be given careful scrutiny.

What is Transhumanism? plombier-nemours.com Transhumanism is a way of thinking about the future that is based on the premise that the human species in its current form does not represent the end of our development but rather a comparatively early phase..
Transhumanism is a loosely defined movement that has developed gradually over the past two decades.
