Example text

Most of the universe is actually made of mysterious, invisible material of totally unknown origin. 03 percent of the universe. In some sense, science is being thrown back centuries into the past, before the rise of the atomic hypothesis, as physicists grapple with the fact that the universe is dominated by entirely new, unknown forms of matter and energy. qxd 10/27/04 7:07 AM Page 12 12 Michio Kaku According to the WMAP, 23 percent of the universe is made of a strange, undetermined substance called dark matter, which has weight, surrounds the galaxies in a gigantic halo, but is totally invisible.

Astronomers as early as Johannes Kepler realized that if the universe were uniform and infinite, then wherever you looked, you would see the light from an infinite number of stars. Gazing at any point in the night sky, our line of sight will eventually cross an uncountable number of stars and thus receive an infinite amount of starlight. Thus, the night sky should be on fire! The fact that the night sky is black, not white, has been a subtle but profound cosmic paradox for centuries. Olbers’ paradox, like Bentley’s paradox, is deceptively simple but has bedeviled many generations of philosophers and astronomers.

No one at the present time has any understanding of where this “energy of nothing” comes from. “Frankly, we just don’t understand it. We know what its effects are [but] we’re completely clueless . . everybody’s clueless about it,” admits Craig Hogan, an astronomer at the University of Washington at Seattle. If we take the latest theory of subatomic particles and try to compute the value of this dark energy, we find a number that is off by 10120 (that’s the number 1 followed by 120 zeros). This discrepancy between theory and experiment is far and away the largest gap ever found in the history of science.
