This is the demand that you prove that something highly unlikely is false. Thus the onus of proof is on the person claiming the existence of a weird thing. If someone says that she knows about unicorns, she needs demonstrate their existence. You do not need demonstrate their lack of existence. Science is a methodology and logical way of thinking verified through experimentation.
Science can momentarily go wrong as in the case of alleged cold fusion a few years ago.
However, in science there is peer review and repetition of valid experiments in different laboratories. When this could not be done in the above case, cold fusion was rejected. Thus science is not arbitrary but is an attempt at being objective. Please write to us about today's piece . This web site is as much yours as it is ours.
