Five amazing journeys will not only transport you to the end of the universe - and back - but also take you deep inside the human body and through the most complex organ imaginable - the brain.

Adventures in Science

Join Ben Silburn as he journeys through a black hole, experiences the creation of a long lasting memory and follows the travails of alcohol as it exerts its debilitating effects round the body. More than just a metaphor, these journeys take place all the time, many right under your nose, without you even realising it.

Journey One: Alcohol

Climb aboard a molecule of alcohol as it travels from the stomach and around the body, exacting revenge following a bout of excessive Christmas drinking.

Journey Two: Black Hole

Journey through the universe into the centre of one of the most dramatic events in the cosmos - a super massive black hole where the force of gravity is so great that not even light can escape and where, on the other side, time and space behave in unimaginable ways.

How do we hear what we want to hear and not what we don't? Follow the sound from an orchestra to your ear - and find out how you block out the coughing and sniffing of the person next to you.
