From a review of Richard Panek’s The 4% Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality. Richard Panek:
The latest surveys of the universe indicate that only 4 percent of it is made of ordinary matter. Nearly 23 percent is made up of dark matter, which some physicists suspect consists of wispy subatomic particles that may someday be caught in a detector. And the remaining 73 percent is made up of something far more baffling: an energy that is causing the universe to expand at an ever-increasing rate. Scientists call it “dark energy,” and they have no idea what it is.

Maybe it’s God.
