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.

Body of Water

There now seems “little doubt” that Saturn’s moon Enceladus holds a “large body of liquid water” beneath its icy surface after a probe returned yet more evidence. “The Cassini probe, which periodically sweeps past the little moon, has returned yet more data to back up the idea of a sub-surface sea. This time, it is the detection of negatively charged water molecules in the atmosphere of Enceladus. On Earth, such ions are often seen where liquid water is in motion, such as waterfalls or crashing ocean waves. There are no ‘rollers’ on the moon but it does have a very active region near its south pole where water vapour and ice particles shoot through cracks in the surface and rise high into the Enceladian sky. ‘We see water molecules that have additional electrons added,’ explained Andrew Coates from University College London's Mullard Space Science Laboratory. ‘There are two ways they could be added - from the ambient plasma environment, or it could be to do with friction as these water clusters come out of the jets, like rubbing a balloon and sticking it on the ceiling,’ he told BBC News.”
