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.

Should We Contact Aliens?

"For five decades astronomers have searched the vast ocean of space in the hope of picking up some kind of radio message from the neighbours. That nothing has been found has not deterred the search for extraterrestrial intelligence, or SETI to the cognoscenti. Despite those years of effort, SETI has done little more than dip a glass into the cosmic ocean, having looked closely at only 750 of the Milky Way’s billion or so star systems. That will soon change. The Allen Telescope Array, a cluster of radio telescopes being built in California with SETI in mind, will dramatically speed up the rate at which such systems can be explored."
