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.

Supernova Smash

January 6, 2010, 6:00 AM
Planet Earth could soon be wiped out by an explosion of a star more than 3,000 light years away according to research by American scientists. “The star, called T Pyxidis, is set to self-destruct in an explosion called a supernova with the force of 20 billion billion billion megatons of TNT. Although the star is thought to be around 3,260 light-years away – a fairly short distance in galactic terms – the blast from the thermonuclear explosion could strip away the Earth's ozone layer, the scientists said. Astronomers from Villanova University, Philadelphia, in the US, said the International Ultraviolet Explorer satellite has shown them that T Pyxidis is really two stars, one called a white dwarf that is sucking in gas and steadily growing. When it reaches a critical mass it will blow itself to pieces. It will become as bright as all the other stars in the galaxy put together, they said. The Hubble space telescope has photographed the star preparing for its big bang with a series of smaller blasts or ‘burps’, called novas.”
