A good theory should explain the observations or results of an experiment or phenomena, being understandable to a lay person while also being reasonable enough to allow for further testings. A good theory should also be frugal in their nature so others can test it, and they should also be predictive.Know More
They should encourage further testing and expansions of the hypothesis. Good theories mean that others should be able to test them and, if possible, disprove them. This doesn't mean that theories should be disprovable, but that they should be designed so that they are neither impossible to be proved or disproved. In this way, theories should be made to facilitate further research and insights, not discourage them.
Theories should be able to predict what will happen from a given experiment. This is what gives them a better standing because their basis is not on pure speculation but informed hypothesizing. Good theories focus on the effects, not the causes of a phenomena. They are also never regarded as statements of fact, but instead of likelihood. Theories aren't regarded as facts because they are frequently revised and rethought. To say a theory is a fact, is to take away the notion that they could ever be further tested and reformed, a practice highly important and regarded by the scientific community.Learn more about Logic & Reasoning

Gas exchange in the lungs allows oxygen to diffuse through the small air sacks or alveoli at the end of one's bronchial tubes into the blood, and it allows carbon dioxide to move from the blood into the alveoli to allow the individual to expel the waste. Fresh oxygen comes into the lungs when one inhales and is removed upon exhaling, according to WebMD.Full Answer >
The nebular theory of solar system formation suggests that stars and their planets form out of cooling interstellar clouds of molecular hydrogen. As the cloud contracts, it forms a disc of dense material that forms the star. As it forms, the star throws off material that coalesces into planets.Full Answer >
