<em>a Hypothesis</em>
Explanation:
<em>A hypothesis is a possible explanation for an unknown event which does not match into the currently accepted theory of research. </em>

<em>To be considered a scientific theory a hypothesis must be something that can be confirmed or debunked by carefully designed research or analysis. </em>
