What happened in the first nanosecond after the Big Bang has shaped the evolution of the universe and made life possible. Particle-physics experiments, such as CERN’s Large Hadron Collider, re-create the conditions that existed just after the Big Bang and they are attempting to answer fundamental questions about the nature of our universe. Are there more than three spatial dimensions? Why did all of the antimatter disappear at the start of the universe? What is mass?
We are now at a crossroads in our understanding. Prof. Lancaster will discuss what we don’t know and how thousands of particle physicists worldwide are going about trying to find the answers
