Knowing that something may change, and believing strongly that right now there is no better answer than the accepted one, are not mutually exclusive points of view. David Milgaard was convicted of the 1969 rape and murder of Saskatoon nursing assistant Gail Miller. He was set free in 1992 after 23 years in jail, and exonerated in 1997 following DNA tests . In 1999, Larry Fisher was convicted of the murder . Here is an acceptable answer.
Scientific laws are the evidence used to support a conclusion.
Scientific hypotheses and theories are our best attempts at explaining the behavior of the world, in ways that can be tested by further experiment. That's most likely a good idea. When talking about scientific laws and theories, you probably should never use the word. Even if you understand it's correct meaning, someone you are speaking to will not. Maybe you know that scientific theories are proven to be supported by observations, but most people won't.
