CBC IDEAS at Perimeter
The Numbers That Shape Our Universe
Wednesday, May 6, [2026[ at 7:00 pm ET
From π to the speed of light, from Planck’s constant to a physicist’s personal “favourite number”, some numbers do far more than describe the universe – they help define it. But what do these numbers actually mean? Why do they matter? And what would the universe look like if they were even slightly different?
Join us for a special episode recording of CBC IDEAS, featuring three Perimeter Institute researchers exploring the fundamental numbers behind reality. Through a mix of fast-paced lightning rounds and deeper reflections, the conversation will bring together vivid explanations, surprising stories, humour, and those unforgettable moments of awe that reveal just how strange – and beautiful – our universe really is.
If you’re unable to attend in person, a recording will be available on our YouTube channel.
Please note that a limited number of tickets are available to the public for this special event.

About the Host
Nahlah Ayed has been the host of CBC IDEAS since 2019. Since then, she has conducted dozens of interviews on-stage and off with some of Canada’s – and the world’s – most prominent thinkers.
A bestselling author and award-winning veteran of foreign reporting, Nahlah was previously based in the Middle East where she spent nearly a decade covering the region’s many conflicts. And later, while based in London, she covered some of the biggest stories of our time: the rise of authoritarianism, the return of war to Europe, and the worldwide refugee crisis.
A former parliamentary reporter for The Canadian Press, Nahlah is a graduate of Carleton University’s Master of Journalism program. She also holds a Master’s degree in interdisciplinary studies (Philosophy, English and Science) and a Bachelor of Science in genetics from the University of Manitoba.
About CBC IDEAS
IDEAS is a deep-dive into contemporary thought and intellectual history. Anchored in a powerful legacy and expansive archive spanning over five decades, its topics are boundless. The nature of consciousness. The history of toilets. The roots and rise of authoritarianism. Near death experiences. No idea is off-limits.
Each episode cracks open a concept to see how it’s played out over place and time – and uncovers why it still matters today.
Tickets
