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.

Dark Matter May Not Be That Mysterious After All

June 12, 2013, 10:30 AM

What's the Latest Development?

Vanderbilt University professor Robert Scherrer and post-doctoral fellow Chiu Man Ho have developed a hypothesis on the composition of dark matter that, unlike other attempts at explanation, can be readily tested using existing underground detectors. Their focus is on the Majorana fermion, a theoretical particle that exhibits a different kind of electromagnetism than most other particles and is undetectable unless it's moving very quickly. "If dark matter, which is thought to be moving much more slowly than it was at the dawn of the universe, is made of Majorana fermions, then that could explain why it's been so hard to spot."  

What's the Big Idea?

Scientists speculate that dark matter makes up about 85 percent of all matter in the universe. The current theory concerning its composition is that it's made of weakly interacting massive particles (WIMPs) left over after the Big Bang. However, nobody has been able to definitively detect a WIMP. Scherrer and Ho's paper, which appeared in a recent issue of Physics Letters B, predicts the rate at which Majorana fermions should appear in the underground detectors and indicates that their existence should soon be discovered or ruled out. Unlike WIMPs, Majorana fermions -- or at least their signatures -- have been detected in past research using crystalline wires.
