We all know the universe is made of planets, starts and a bunch of other floating objects but what about the emptiness, the dark matter and the Higgs boson. Grab a beer before boarding on our spaceship!
The Dark Secret of the Universe
Kevin Graham (Professor Physics Department, Carleton University)
During the last 100 years, we have made progress in understanding the structure and composition of our universe. From the smallest length scales of subatomic particles, to the evolution of the cosmos over 13.8 billion years, an impressively detailed picture of our universe has emerged. But there are still mysteries to be solved. By the end of the 20 th century we discovered that most of the matter content of the universe, about 85%, is some completely unknown ‘Dark Matter’. In this talk, I will describe how this mystery was discovered and some of the ongoing efforts aimed at trying to solve it
The Higgs Boson and the Ground of Being
Heather Logan (Professor Physics Department, Carleton University)
Almost seven years ago particle physics was rocked by the discovery of the Higgs boson — the long-predicted “missing piece" of the Standard Model. People say the Higgs "gives mass", but what does that really mean? In this talk, I'll explain the role of the Higgs within our understanding of nature, and explain what the ongoing experiments are trying to find out about it.
