If there's one thing that unites us all (literally, ALL of us) it's gravity. Gravity attracts every bit of matter in the universe to every other bit of matter in the universe, no exceptions! But for something (a warping of space-time, to be precise) so universally present, it remains one of the least understood forces in physics.
Physicists from Newton, to Einstein, to Hawking, to countless others have for centuries sought to understand the true nature of gravity. And now there are cutting-edge new theories which may yet solve some of its deepest mysteries. This hour we speak with physicists and science writers about the weird world of gravity.
