Season 2 of "What If" takes you to an imaginary world where the laws of nature have been altered, changed.

INSH and ScienceNaturePage are proud to present Season 2 of “What If”, a Facebook Watch where we ask some of the most provocative hypothetical questions in science — and then try to answer them. In every episode we showcase one of these questions, and use the latest findings and research in modern science to look for answers.
