A scientific theory is a well-tested, comprehensive explanation of an important feature of nature supported by evidence and facts gathered over time (Oregon State). These theories are typically proposed by one scientist or researcher and then retested and reexamined over time by other scientists and researchers, who will either agree with and add onto the original theory or will find evidence against it and eventually debunk it.
Debunked scientific theories are these theories that were once widely accepted within the mainstream scientific community but nowadays are considered to be inaccurate descriptions of nature. Often times, these debunked scientific theories are only disproven when scientists and researchers work to retest the original theory and another theory emerges from this research to replace it as the norm. In this anthology, a series of famous debunked scientific theories, such as the Flat Earth Theory or the idea of Geocentrism, are given an in-depth look.
