Despite what you may think, the universe is not necessarily a friendly place. Sure, things here on Earth have been pretty stable over the past few millennia, allowing human civilization to gain a foothold. But that could change at any time. Disaster lurks everywhere, from the deepest reaches of space to the very bowels of our planet. We’ve recruited nine prominent Canadian scientists (and one science fiction writer) and asked them to imagine how they think the world might end.

Catch a Wave — Let there be light. Otherwise we couldn’t watch a sunset or YouTube. Yet what your eye sees is but a narrow band in the electromagnetic spectrum. Shorten those light waves and you get invisible gamma radiation. Lengthen them and tune into a radio broadcast. Discover what’s revealed about our universe as you travel along the electromagnetic spectrum. There’s the long of it: an ambitious goal to construct the world’s largest radio telescope array … and the short: a telescope that images high-energy gamma rays from black holes. Also, the structure of the universe as seen through X-ray eyes and a physicist sings the praises of infrared light. Literally. And, while gravity waves are not in the electromagnetic club, these ripples in spacetime could explain some of the biggest mysteries of the cosmos.
