In more detail: the scientific method involves making conjectures (hypothetical explanations), predicting the logical consequences of hypothesis, then carrying out experiments or empirical observations based on those predictions. [4] A hypothesis is a conjecture based on knowledge obtained while seeking answers to the question.
The use of a sequence of experiments, where the design of each may depend on the results of previous experiments, including the possible decision to stop experimenting, is within the scope of sequential analysis, a field that was pioneered [13] by Abraham Wald in the context of sequential tests of statistical hypotheses.

Wheeler's cosmic interferometer uses a distant quasar with two paths to equipment on Earth, one direct and one by gravitational lensing. After [2]. In an attempt to avoid destroying normal ideas of cause and effect, some theoreticians [who?] suggested that information about whether there was or was not a second beam-splitter installed could somehow be transmitted from the end point of the ...
A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence have been accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence. A theory will always remain a theory; a law will always remain a law.
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on ...
A thought experiment is a hypothetical situation in which a hypothesis, theory, [a] or principle is laid out for the purpose of thinking through its consequences. The concept is also referred to using the German-language term Gedankenexperiment within the work of the physicist Ernst Mach [ 2 ] and includes thoughts about what may have occurred ...
The hypothesis of Andreas Cellarius, showing the planetary motions in eccentric and epicyclical orbits. A hypothesis (pl.: hypotheses) is a proposed explanation for a phenomenon. A scientific hypothesis must be based on observations and make a testable and reproducible prediction about reality, in a process beginning with an educated guess or ...
This calls for a need to conceptually switch from hypothesis-driven studies to hypothesis-generating research which is discovery-based. [4] Normally, discovery-based approaches for research are initially hypothesis-free, however, hypothesis testing can be elevated to a new level that effectively supports traditional hypothesis-driven studies.
