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.

How Saturn Got Its Rings

December 13, 2010, 7:08 AM
A sophisticated computer model demonstrates how tidal forces on Saturn could have peeled away the icy outer layers of a large moon that occupied an unfortunate piece of real estate. After pulling off the ices, the gravity of Saturn would have doomed the moon's silicate core, tugging it closer and closer until it smashed into the planet, the simulation shows. The theory neatly accounts for why Saturn's rings are nearly pure ice, while most objects in that part of the solar system are more an ice-rock blend. Planetary scientist Aurélien Crida, with the Université de Nice Sophia-Antipolis, France, notes that the stripped-off ice would have swirled in rings about 1,000 times more massive than what exist today.
