Is science 100% right?

No, science is not 100% accurate because it's a process of continuous learning and refinement, relying on the best available evidence, but always open to new discoveries that might revise current understanding, meaning scientific knowledge involves varying degrees of certainty, not absolute proof. While theories can be incredibly reliable and predictive (like gravity), science acknowledges potential limitations in observation and interpretation, aiming to become "less wrong" over time rather than achieving perfect, final truth.
