What is out there? The expected and unexpected matters

When you look up through a clear sky on a dark night you may wonder what is out there apart from the stars and the moon.  However, this is not an easy question to answer, even for a scientist.  So far, most scientists only study a small, known, part of the material universe.  So far, the scientists only study a small part of the universe.  The rest of the unknown universe they describe as ‘dark matter’ and ‘dark energy’.

How does knowledge of the “known” allow scientists to anticipate consequences of the “unknown”?

In one of series of the Global Catastrophic Risks Conference, Dr Michelangelo Mangano, senior theoretical physicist at CERN, the European Centre for Particle Physics, talks about this topic and explains, for example, why the chance of strangelets and black holes being created by the Large Hadron Collider are risks so very unlikely as to be practically impossible, and does the math behind this matter when there are issues with communicating the results to a public that often does not understand Newton’s laws?
