What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

X-Rays Take Researchers Inside a Supernova

We are made of exploding stars: from the iron in our blood to the calcium in our bones. It all comes from supernova explosions, and now researchers can look inside the center of one. Cassiopeia A was once a star with a mass over eight times greater than our sun. Over 300 years ago, it died, creating an inferno, and NASA has been shifting through its radioactive ashes using the NuSTAR space telescope. The telescope array generated the first map of radioactivity; Nature published NASA's findings on Wednesday, as reported by CNN. To better understand how scientists study supernovas check out Big Think's interview with Ray Jayawardhana, an astrophysicist at the University of Toronto and the author of Neutrino Hunters: The Thrilling Chase for a Ghostly Particle to Unlock the Secrets of the Universe.
