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.

Chemical Afterlife

A beckoning light; a feeling of transcendence: these are two characteristics of a near-death experience that new research suggests may relate to amounts of certain chemicals in the blood. "The phenomenon known as 'near-death experience' is the stuff of hospital dramas, a dramatic conceit for movies about do-overs and for a (I guess lucky) few of us, a mysterious peephole to 'the other side.' The phenomenon is very real: By various estimates, 11% to 23% of those who had experienced cardiac arrest and lived to tell about it report some unique cognitive experience -- an overwhelming feeling of transcendence, doors opening, beckoning light, a thumbnail life-review -- that broadly fits the description. (The Internet yields a bounty of personal accounts as well, so it must be real!) But their observations are not very well explained -- not, at least, by standard earthly measures."
