Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore -- there are huge yawning voids in our basic notions of how the world works.

And although the universe is full of weird things that don't make any sense, Cham and Whiteson make a case that the questions we can't answer are as interesting as the ones we can, and they invite...

Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor. Although these membranes were leaky, the environment within them became different from the raging maelstrom beyond. These havens of order slowly refined the generation of energy, using it to...
