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.

Theoretical Physics Doesn't Pass Monty Python Test: "Cut it Out. That's Silly."

Multiverse

What's the Latest?

A theoretical contradiction may lie at the heart of the multiverse theory, which says that our universe is but one in a series of potentially infinite universes. It's hard to believe that physics comes down to the sort of logic that follows, but here it is: "In the split second after the big bang, the universe is thought to have gone through an explosive growth spurt known as inflation...and every so often an inflaton would be randomly infused with extra energy, blowing a separate bubble universe into existence. That bubble would itself go through inflation and in turn blow more bubbles, leading to the idea of the bubble multiverse."

What's the Big Idea?

So by this thinking, once inflation starts it can never really end, and new universes are always being born--so this multiverse is infinite and endless. Now here's where it gets good. "In such an infinite multiverse, everything that has even a slight chance of happening is virtually certain to happen--you just need to wait long enough." Taken to its logical conclusion, that includes the spontaneous aggregation of matter so that it creates self-aware, disembodied brains. "The problem is that  the starting point for our understanding of the universe and its behaviour is that humans, not disembodied brains, are typical observers."
