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.

Question: How is NASA’s shrinking budget affecting your work?


Heidi Hammel: Well, NASA’s budget has not really been declining. It’s been stable, and it’s been a very, very tiny but, you know, stable fraction of our government’s budget. I think that there’s a lot we can do with the NASA funding now. Certainly it could be more if we had more, but we’ve got a lot of things going on in our country. I don’t think I could advocate for increasing NASA’s budget by a factor of two or ten, because I want us to have good roads in our country. I want us to have good education in our country. And NASA’s budget is part of a discretionary budget, and we can’t make that bigger without taking away other things. And so I try to be pragmatic about that and, you know, we just have to do with what we’ve got. What that does mean is that those of us who are space scientists need to be very realistic about what our expectations are. We need to be very thoughtful about how we propose to spend the money that NASA does have for space exploration. And we need to be clear that there’s the human spaceflight part of NASA, and there’s the science space part of NASA, and there’s also aeronautics. Those are all very different things that NASA does. The space-science part of NASA, the part that’s launched the Hubble Space Telescope, and put the rovers on Mars, that’s about one-third of what NASA does. And it’s been a really productive one-third of what NASA does. Should it be a bigger part? Should it be half? I don’t know. Maybe the third is the right amount. But we need to be very thoughtful about what we propose to do and recognize we’ve got limited resources. We can’t do everything, so be careful.
