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.

First Radar Images Show Asteroid Passing Earth Has Its Own Moon

May 31, 2013, 10:39 AM

Asteroid 1998 QE2 will be passing Earth today at 4:59 p.m. Eastern, at a distance of 3.6 million miles, or about 15 times the distance between Earth and the moon. That is still much too close for comfort, as a collision would mean global extinction. This event has reignited the debate about whether we are doing enough to detect other potential cosmic collisions.

In the meantime, we are learning more about asteroid 1998 QE2 the closer it gets. In fact, the first radar images of the space rock were obtained on May 29 when the asteroid was about 3.75 million miles from Earth. These images revealed 1998 QE2 is a binary asteroid, meaning it has its own moon. In the images above, the moon is the small white dot at lower right.
