The null hypothesis might be: There will be no difference in spin speed between a turbine with 6 versus 8 blades. The cell is the smallest unit of structure and function of all living organisms, all living organisms are made up of at least one cell, and living cells always come from other living cells. Though the findings confirm the hypothesis, there may be a tomato of that type somewhere in the world that isn't red. While speaking to a colleague, a scientist makes . The null hypothesis predicts that there will be no relationship between the variables tested, or no difference between the experimental groups. A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon.For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it.

In some instances, rather than rejecting a hypothesis because it has been falsified by new evidence, scientists simply adapt the existing idea to accommodate the new information. On the other hand, if results contradict a hypothesis, that hypothesis is probably not correct. Several examples include the idea that living organisms develop from nonliving matter, which formed the basis of spontaneous generation, a hypothesis that ultimately was disproved (first in 1668, with the experiments of Italian physician Francesco Redi, and later in 1859, with the experiments of French chemist and microbiologist Louis Pasteur); the concept proposed in the late 19th century that microorganisms cause certain diseases (now known as germ theory); and the notion that oceanic crust forms along submarine mountain zones and spreads laterally away from them (seafloor spreading hypothesis).

Whenever we have an unexplained scientific phenomenon, we crowd-source explanations for the phenomenon and each prospective scientific explanation that can be tested using scientific methods and each proposal is called a hypothesis.
