Question

1. What is the difference between science and pseudoscience?

Answer 1

A science is a body of hypothesis based upon observation and experiment. “Scientific facts” are not science; they are only the results of these observations and experiments. The hypotheses of science are subject to revision based upon what is observed in the world. A scientist makes observations using the current hypotheses trying to disprove (or falsify) one or more of these hypotheses. These hypotheses will, in the end, be revised or discarded if they fail to match reality. As such, science should be ultimately self-correcting. If repeated observations fail to disprove a hypothe¬sis, it is considered increasingly reliable as a guide and is referred to as a “theory” or as a “law.” A pseudosciences is a body of hypotheses treated at true, but without a consistent body of supporting experimental evidence. These hypotheses are not subject to revision. A pseudoscientist makes observations or experi¬ments designed to prove their original hypotheses. This attempt to prove rather than disprove is the major distinguishing feature between science and pseudoscience.

Answer 2

in short, science has predictive abilities while pseudoscience doesn't.

e.g. we can send rockets to the moon because we can predict the paths and velocities of the earth, the moon and the rocket.
