What makes the universe tick? Can atoms cast shadows? The second night of Pint of Science will provide answers to these and other quantum physics questions as two researchers from Griffith's Centre for Quantum Dynamics present their work. Be sure to bring a friend, because on Tuesdays the kitchen at Parky puts on an awesome deal: buy one main meal, get the second for $7.
What makes the Universe tick?
I'll show how time as we know it can be traced to a particular quantum effect. If this effect was absent, the universe would be stuck at one time. Adding the effect makes the universe extend over all times into the present and beyond.
An atom's shadow
Shadows are a familiar sight. They are formed by the absence of light. Something dark in front of something bright. A child with a torch in the night can make shadow puppets with their hand. But what is the smallest thing that can cast a shadow?
