Gravity is not a force acting at a distance. It is mass gripping spacetime, telling it how to curve, and spacetime gripping mass, telling it how to move. According to preeminent physicist John Archibald Wheeler, gravity makes the closest connection between the world we see around us and the inner-most workings of the universe.

In this imaginative volume, Wheeler explores gravity and spacetime by applying Einstein's battle-tested theory to both familiar and exotic phomomena--everything from flying tennis balls, to hurling gravity waves from crashing stars, the motion of the planets, and the collapse of a star into a black hole. It's a provocative, revealing, fully engaging scientific journey led by a frontline participant in the most important work in physics in the last 50 years.
 

Great men, great ideas
from fall to float
interval - revelation that all of space is ours
boomerang through the Earth
tides - the grip of mass on spacetime
momenergy - the grip of spacetime on mass
the boundary of a boundary - where the action is
from potter's wheel to space geometry
picturing space and spacetime around a centre of mass
stones in flight and planets in orbit
gravity waves
black holes
a farewell look at gravity.

John Archibald Wheeler is Joseph Henry Professor Emeritus at Princeton University and was, until his retirement, Blumberg Professor of Physics and Director, Center for Theoretical Physics at the University of Texas at Austin. A past president of the American Physical Society, he is a recipient of the Enrico Fermi Award (1968), the National Medal of Science (1971), the Niels Bohr International Gold Medal (1982) and the Wolf Prize (1997).
