Hypotheses are ideas which are, as yet, unsupported by evidence. As a hypothesis becomes backed up by mathematical formulae and observational data, it may, if it is sound, become a theory. All scientific theories began life as hypotheses, it is merely a case of which hypotheses become theories, and which fall down by the wayside after being discredited or having lacked support.
A law cannot become a theory, as laws are higher in scientific hierarchy than theories. Theories may become laws when the evidence for their factuality proves that the theory meets all established requirements set forth by the theory. If at any point in the scientific method a theory is disproven for the criteria that it sets forth, it can never be considered a Law. The hierarchy is thusly: Hypothesis < Theory < Law.
because some scientific theories are not true for this advanced world. e.g. the early ideas about phlogiston.
People tend to say that scientific theories are "just" a theory because of a confusion between the common usage of "theory" and the scientific definition. (In everyday speech people often use the word "theory" in the sense of a "hunch" or "vague idea". This is not what the word means in a scientific context). A scientific theory is deduced from observations and is the simplest way of describing natural phenomena. It is testable, observable, predictable, and falsifiable. Scientific theories are not the same thing as hypotheses, which are explanations that haven't been demonstrated or verified. A scientific theory has evidence to back it up. The common usage of 'theory' suggests an explanation that someone hasn't proven, or isn't able to prove. It doesn't imply evidence that has been tested; it doesn't imply predictability. When someone hears, for example, "Big Bang theory" or "the theory of evolution", they may hear the word 'theory' and associate those scientific theories with someone's opinion or suggestion. In reality, these theories are the best scientific explanations for a myriad of phenomena across multiple scientific definitions. In science, "just a theory" is a very good place to be.
Scientific theories are explanations of natural phenomena based on observation and experiment. Current theories represent the best possible explanation given the most current information but are not meant to be the final explanation. The best, most reliable theories withstand the test of time and new discoveries, such as the Einstein's theory of general relativity or Darwin's theory of evolution. New discoveries may add to the detail of these theories or confirm their reliability in describing the phenomenal world, but no discovery so far has shown either of these theories to be false. The best theories also lead to testable predictions which either confirm or falsify the validity of the theory.General theory, or theory as used in every day language, more often describes a guess or conjecture and is closer to the scientific idea of a hypothesis.
A process in which scientists father facts through observations and formulate scientific hypotheses that may eventually become theories.
Theories can evolve and change over time as new evidence is discovered or different perspectives are considered. They may be refined, expanded upon, or even replaced by new theories that better explain a phenomenon. Additionally, theories may become widely accepted within a scientific community or society as a whole as they stand the test of time and scrutiny.
Hypotheses are ideas which are, as yet, unsupported by evidence. As a hypothesis becomes backed up by mathematical formulae and observational data, it may, if it is sound, become a theory. All scientific theories began life as hypotheses, it is merely a case of which hypotheses become theories, and which fall down by the wayside after being discredited or having lacked support.
Some scientific theories suggest that over EXTREMELY long time periods, protons themselves can decay. If so, then a few trillion years from now, the universe may eventually decay into a sea of free neutrons.
A law cannot become a theory, as laws are higher in scientific hierarchy than theories. Theories may become laws when the evidence for their factuality proves that the theory meets all established requirements set forth by the theory. If at any point in the scientific method a theory is disproven for the criteria that it sets forth, it can never be considered a Law. The hierarchy is thusly: Hypothesis < Theory < Law.

All scientific explanations of anything, if they are backed by substantial evidence, are classified as theories. If they have not been backed by substantial evidence then they are classified as merely hypotheses. No matter how good a theory may be, we can never be absolutely certain that someone will not eventually come up with an even better explanation, hence, theories remain theories, they are not Absolute Truth.
A Scientific Law is a discriptive generalization about how some aspect of the natural world behaves under specified circumstances. A Scientific Theory is a well substantiated explaination of some aspect of the natural world that incoporates facts, laws, and tested hypotheses. Scientific laws are descriptive. They do not seek to explain phenomena, whereas scientific theories do.
Yes, but it can always be proven wrong. Nothing in science is for sure right.
