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.

The Big Idea for Sunday, May 25, 2014

One day, in the not too distant future, space tourism will be as normal as packing up the family to see the Grand Canyon. The Moon may even well become a hot honeymoon destination. How can this be when the cost of sending fragile humans into space is immense?  

Michio Kaku, author of The Future of the Mind, says that the technology--robot surrogates--is already being advanced by the Honda Corporation. Us feeble humans will one day be able to experience the Moon and Mars through our robot surrogates--or robonauts--that travel to space on our behalf. The experience will feel just as real to us earthlings thanks to pods we enter or helmets we wear to see what our robonauts see.  

Today's big idea explores the future of space travel.
