A CYCLIC UNIVERSE?
What caused the Big Bang? Did it have a cause? Or did it begin time,
creating itself by its bootstraps? These philosophical puzzles have
bothered astronomers for decades. Now two cosmologists are proposing a
radical new theory in which the Big Bang resulted from the death of a
previous era of the cosmos, part of an infinitely old cycle of collapses
and rebirths.
The idea of a cyclic universe has been around ever since the Big Bang was
first proposed in the 1930s. But no one could find a way to make the "big
crunch" that ends one cycle of the universe "bounce" to become the big
bang of the next.
Now, using tools from the outer reaches of theoretical physics known as M
theory, along with concepts of spacetime "branes" moving through higher

new visible-light camera in nine years. Compared with the telescope's
workhorse, the Wide Field and Planetary Camera 2, the ACS covers more than
twice as much sky with sharper resolution and higher sensitivity. Its 17-m
egapixel detector array records a patch of sky 3.4 arcminutes square,
about one-ninth the apparent diameter of the Moon....
