Falsifiability in physics

Falsifiability in physics means that a scientific idea must be testable in a way that could prove it wrong. If a theory makes predictions, experiments can be designed to check them. If results consistently contradict the predictions, the theory must be reconsidered. This concept helps distinguish scientific theories from beliefs or guesses—they are considered scientific only if they can be tested and potentially refuted by evidence. Falsifiability ensures that scientific progress relies on experiments and open questioning, maintaining the integrity and reliability of our understanding of the universe.
