Belief is important in science. In science we only disprove a hypothesis (falsifiability). If we repeatedly fail to disprove it we begin to believe it true.

Belief is important in science. In science we only disprove a hypothesis (falsifiability). If we repeatedly fail to disprove it we begin to believe it true. Yet we can never rule out that one data the data may exist to disprove our strongly held hypothesis. We never prove it true we simply believe it true based on the continual failure of disproof.
