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.

Can Atom-Sized Black Holes Pass Through Earth?

What's the Latest Development?

A team of astrophysicists have recently simulated the extraordinary event of an atom-sized black hole passing through planet Earth. The scientists theorize that such tiny black holes, called primordial black holes, were created when early galaxies breached a density threshold and underwent gravitational collapse. It is believed that these black holes, if they exist, would be composed partly of dark matter. Thus the scientists' priority is now to prove the existence of these black holes beyond current theories, helping to make the case for dark matter's existence.

What's the Big Idea?

To prove the existence of these atom-sized black holes, scientists would look for evidence that they had passed through the Earth in the past. The famous Tunguska impact in Siberia in 1908, where no comet ash has ever been found, could be the location where a tiny black hole entered its path through the center of the planet (though leaving open the question about where it exited). Astrophysicists say the black holes present no existential danger to Earth and that if one were to pass through the planet, it would feel like a minor earthquake in every part of the globe.
