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.

Is the James Webb Telescope Bankrupting NASA?

What's the Latest Development?

The space telescope which could peek into the origins of the universe continues to be built, despite having caused a major rift with Congress last year when some of its members tried to cut the telescope's funding. Estimated to cost $500 million, the price now stands at $8.8 billion. But there have been groundbreaking technical achievements along the way: the telescope's mirrors are six times larger than Hubble's, so they must be folded up for the launch; a tennis-court sized shade will extend in space to keep the sensors cool enough to detect faint light.

What's the Big Idea?

If successful, the James Webb Telescope would demonstrate America's technical superiority in space. The telescope's main purposes will be to examine the chemical makeup of exoplanets' atmospheres (water would be an interesting find) and to detect the universe's first rays of light, which by now have shifted to the infrared spectrum and exist at the limits of the known universe. The danger of the project is that its costs may encourage Congress to give NASA funding for a flagship project once a decade, rather than once every few years.
