Popper's Falsifiability

Popper's falsifiability is a principle in scientific philosophy that suggests a theory is only valid if it can be tested and potentially disproven. In other words, for an idea to be scientific, there must be a way to show that it could be wrong through observation or experimentation. If a theory cannot be tested or could never be proven false, it doesn't qualify as scientific knowledge. This approach emphasizes that science progresses by eliminating false ideas rather than proving them right, leading to a more reliable understanding of the world.
