Over the final decades of the 20th-century astronomers realised that most of the Universe is missing. When we look up into space with our most powerful telescopes we are only glimpsing a tiny fraction of what’s out there. In fact, every galaxy, every star, every planet, and every spec of dust in the night sky accounts for just 5% of the Universe.
The remaining 95% is completely unknown, dominated by enigmatic substances called dark matter and dark energy. Today, scientists from all over the world are trying to prize open a window into this hidden world, a scientific mission with the potential to transform how we think about the cosmos and our place in it.
In this fascinating talk, particle physicist Dr. Harry Cliff takes us on a tour of the Dark Universe, revealing how we came to realise that most of the Universe is missing, and telling the story of the ongoing quest to discover its true nature.
