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 Explosion Discovered by Fluke

January 23, 2014, 3:14 PM

The light from an exploding star in the Messier 82 (aka "Cigar") galaxy was first photographed from Earth on January 22nd, 2013. The galaxy is ~12 million light years away so the explosion occurred about 12 million years ago.

A new supernova has not been observed so close to our solar system in over 20 years. This one was discovered by students and staff at the University of London Observatory. According to a press release, the discovery was a fluke

"The weather was closing in, with increasing cloud," explains Dr Steve Fossey, "so instead of the planned practical astronomy class, I gave the students an introductory demonstration of how to use the CCD camera on one of the observatory’s automated 0.35–metre telescopes."

The students happened to choose M 82, since it was in one of the shrinking patches of clear sky. "While adjusting the telescope’s position," the press release reads, "Fossey noticed a ‘star’ overlaid on the galaxy which he did not recognize."

According to the astronomer Ray Jayawardhana, the supernova was "too far *and* of the wrong type" for neutrino detection. 

Watch Jayawardhana explain how a supernova might be identified via neutrino detection in the video here:
