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.

393 - The Unevenness of Space-Time Convergence

June 20, 2009, 10:03 AM


How long does it take to travel from London to elsewhere? The answer is provided by this map, showing a set of expanding circles centered on the British capital, each bigger one delineating two extra hours of travel time.

The familiar shape of the world is morphed into grotesque, contorted shapes as these isotemporal lines replace the usual lines of longitude and latitude for frame of reference. Not surprisingly, as different modes of transport must have been taken into account: fast transatlantic jet to New York, slower ground-based transport (car or train) to Penzance. This makes the difference in travel time to both cities from London less than 2.5 hours, while the actual distance between both is a formidable 3,264 miles (5,253 km).

This map predates the opening of the Eurotunnel, which has allowed faster connections between London and Paris (about 2 hours) than shown on this map. Travel time distances from London are:
