Natalija [7]

Answer:

b. False

Explanation:

A scientific theory must have strong support from testable facts that are confirmed (or rejected) by observational and/or experimental procedures. The scientific method is a rigorous process that consists of arising a conjecture (hypothesis) which can be subsequently used to make predictions from its logical consequences, and finally to obtain information from empirical observations/experiments in order to obtain a conclusion about the veracity of the scientific claims (i.e., a hypothesis must be testable). In consequence, a scientific theory can not be based only on 'light' conjectures, but trustworthy observational data from the real world.
