If they are mathematicians they can prove a theorem. In the physical sciences theories cannot be proved. The current theory is the one that fits the experimental evidence more closely than all alternative theories. When a new theory comes along that is more accurate, the old theory is superseded.
It is important to be able to test the hypothesis because testing your hypothesis is how you prove or disprove your theories. If it is disproved then you can change your hypothesis.
Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.
My source Ruth Czarneki tells us about this. The study of neurobiology has long involved the actions and interactions among neurons and their synapses. Changes in concentrations of various ions carry impulses to and from the central nervous system and are responsible for all the information processed by the nervous system as a whole. This has been the prominent theory for many years, but, now, there is a new one to be reckoned with; the Quantum Brain Theory (QBT). Like many new theories, the QBT has merits and flaws. Many people are wholeheartedly sold on it; however, this vigor might be uncalled for. Nevertheless, this could prove to be a valid and surprisingly accurate theory of brain function.
If we're in the realm of newtonian physics I would say that it couldn't be in motion relative to a reference point, of course quantum physics and seems to prove everything we believe wrong.
Postulating in mathematics is simply stating stating or assuming something, usually an equation, to be true without having to prove it. This aids in the development of new mathematical theories. Commonly used postulates are Einsteins theories and his laws of the physics.
An experiment can prove they are wrong or right ...:)
Steven Hawkings theories are not able to be proved, for they include quantum gravity, and subatomic particles and before and after the existence of our universe. That's why theories are theories, they are explanations for phenomenas that are observed. Some theories can be comfirmed, but quantum usually cannot be tested, such as time travel and just how 100ft waves are possible due to how large scale and how unpredictable energy can be transfered to from wave to wave resulting in radical amplitudes. One main reason is because his ideas about subatomic particles cannot be contained, they have no mass, nor electric energy.. They do however have energy when momentum is involved. No experiments can accurately explain these theories.

It will prove the existence of the Higgs Boson. So far it is only theory. This is a groundbreaking result as particle physics has been without new data for over a decade to decide what theories are correct.

Calculus was created to prove physics which defines the laws of nature.
In crossing over and random assortment.
If one has a theory, one can conduct research to prove or disprove the theory ... and if one conducts research, the knowledge gained can lead to formulation of new theories, which research can prove or disprove and lead to new theories which can be researched ... prove or disprove and lead to new theories which can be researched ... prove or disprove and lead to new theories which can be researched ...
Scientists have no imagination, that's why they have to PROVE theories to be facts.
