Does a theory Need evidence?
” A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
Such fact-supported theories are not “guesses” but reliable accounts of the real world.”.

Are evidence and proof the same thing?
In some areas of epistemology and theology, the notion of justification plays approximately the role of proof, while in jurisprudence the corresponding term is evidence, with “burden of proof” as a concept common to both philosophy and law. In most disciplines, evidence is required to prove something.
Can a theory ever become a law?
A theory does not change into a scientific law with the accumulation of new or better evidence. A theory will always remain a theory; a law will always remain a law. Both theories and laws could potentially be falsified by countervailing evidence. Theories and laws are also distinct from hypotheses.

Is gravity a theory or a fact?
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass.
How does something become a fact?
In science, a fact is a repeatable careful observation or measurement (by experimentation or other means), also called empirical evidence. … In the most basic sense, a scientific fact is an objective and verifiable observation, in contrast with a hypothesis or theory, which is intended to explain or interpret facts.
What is theory of science?
A theory is a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses. … A scientist makes an observation of a natural phenomenon.
What makes a theory valid?
If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon. … Theories may change, or the way that they are interpreted may change, but the facts themselves don’t change.
What is the difference between a law and a theory?
In general, a scientific law is the description of an observed phenomenon. It doesn’t explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory.
What is proof in law of evidence?
