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.

Does Gravity Explain Physics' Mysteries?

What's the Latest Development? 

A new theory about gravity has been put forth that could tie the loose ends of contemporary physics. Edmund Schluessel of Cardiff University says that large waves of gravity which disrupt the space-time grid could still be rippling through the universe billions of years after the big bang set them in motion. Those ripples could be strong but subtle enough to warp our observations of the universe while simultaneously keeping us from detecting the waves directly. If the waves affect the refraction of light, many of our current observations could be thrown into doubt. 

What's the Big Idea?

Schluessel's hope is not to through us into more doubt but to resolve the apparent contradictions of contemporary physics. When physicists observed an expanding universe, for example, they were required to posit dark matter, yet this driving force of the cosmos has yet to be directly observed though it theoretically composes over 70 percent of everything we "know". Recent observations have also suggested that the universe may be expanding faster in some regions than in others contradicting the long-held cosmological principle which states physical laws are constant across the universe.
