Physics of the very small (high-energy particle physics) and the very large (cosmology) have come together to provide an amazingly unified view of the universe.

Our understanding has evolved to an unprecedented level of precision, but also leaves major unanswered questions, such as the nature of dark matter and dark energy.

In this lecture, Professor Volkas discusses astrophysics and particle physics and provides insight into astronomical observation and high-energy particle collider experiments.

This lecture is part of the July Lectures in Physics series which provides insight into fundamental questions in physics.
