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 Gets More Mysterious

October 19, 2011, 1:30 PM

What's the Latest Development?

A recent study of two far off dwarf galaxies challenges the standard cosmological model by presenting contrary observations of dark energy. Rather than dark matter being concentrated at the center of the Fornax and Sculptor galaxies, as the standard model would predict, researchers at the Harvard-Smithsonian Center for Astrophysics found that it was distributed equally among the millions of stars they observed. "After completing this study, we know less about dark matter than we did before," said the lead author. 

What's the Big Idea?

With galaxies like our Milky Way rotating through space at incredible velocities, why don't their stars go flying off in all directions? The answer is dark matter. The gravitational force which keeps our feet on the ground, thanks to Earth's mass, is simply not strong enough to keep entire galaxies together. As a solution, scientists have concluded that another kind of matter, dark matter, keeps stars turning around the center of galaxies. Accordingly, dark matter should be concentrated at their centers.
