For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter—atoms—accounts for only 4% of the weight of the cosmos. The rest—dark matter and dark energy—is invisible to our telescopes.

Getting old is an unavoidable truth of life. And yet, for most of modern history this mortal coil has baffled scientists.

From diseases and disasters to the miracles wrought by evolution, the environmental forces that shape our lives are the inspiration for countless science writers. This event featured five award-winning authors whose best-selling books explore the complicated interplay of science, ethics, history and social responsibility.

Extra dimensions of space — the idea that we are immersed in hyperspace — may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still — but ultimately hit a dead end.

Looking millions of light-years into deep space requires a special kind of glass telescope. Prior to the 1980s telescopes were limited in size and too heavy to follow the motion …
