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.

Scientists Announce They've Found the Higgs Particle

July 4, 2012, 7:42 AM

What's the Latest Development?

This morning, scientists at the CERN laboratories in Geneva, Switzerland, announced they have found the Higgs boson, the world's most sought-after particle. "Higgs boson with a mass of around 125 to 126 gigaelectronvolts (GeV) was seen separately by the twin CMS and ATLAS detectors at the Large Hadron Collider, each with a confidence level of 5 sigma, or standard deviations, the heads of the experiments announced today at CERN." The level of 5 sigma is a rigorous statistical benchmark meaning that the evidence of the Higgs particle has just a 5-in-10 million chance of being a fluke.

What's the Big Idea?

The Higgs boson is the last remaining particle predicted by the Standard Model, the set of equations which describe how the Universe functions on a subatomic level. Many see the discovery of the Higgs as a triumph of contemporary physics and a confirmation of our ability, as a species, to grasp the strange mechanics of the Universe. Still, the results from CERN are preliminary and whether the new particle exactly fits the Standard Model's predictions remain unknown. Since the Model does not account for either gravity or dark matter, scientists will continue to gather data on the Higgs to determine the accuracy of the Standard Model.
