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.

A Black Hole Mystery Revealed

November 20, 2013, 12:49 PM

The image above is an artist's illustration of the 4U1630-47 star system featuring powerful jets emanating from a black hole candidate that is just a few times the mass of our sun.

So what type of matter is contained in these jets?

The jets have an overall positive charge, which means they must contain something other than electrons. And indeed, according to a study in the journal Nature, the jets were also composed of normal matter such as nickel and iron. The authors of the study therefore suggest the jets are carrying more energy away from the black hole than was previously known.
