Abstract

Cosmology in the 21st Century

Revolutionary progress has been achieved in the science of cosmology over the past 30 years. Powerful experiments, made possible by new technologies, have transformed our understanding of the universe. We have unveiled the laws of physics that govern time and space on the grandest scales, from the big bang to present day.

The universe, we’ve learned, is full surprises. For instance, dark matter – the invisible gravitational glue that permeates the vast majority of the universe – remains one of the greatest unsolved puzzles of astrophysics. Nor do we yet fully understand the quantum mechanical nature of the big bang, or the universe’s current transition into a new stage of rapid expansion.

Perhaps most surprising is how remarkably simple these phenomena are to describe, yet so vexing to comprehensively explain.  But as the pace of discovery continues to accelerate, so too will our ability to decode these grandest of puzzles.

During his public lecture, Perimeter Institute cosmologist Kendrick Smith will take the audience on a journey of discovery through the expanding universe, from the big bang to our present-day understanding of dark matter and other cosmic phenomena. He will explore the yet-unsolved mysteries of the universe, and explain how new research aims to shed light on these deep questions.
