| Popular Lecture: Our universe is expanding and galaxies move away from one another. In the nearly eighty years since Einstein and others first wrestled with this fact, we have learned much about the history of the cosmos, but we have also uncovered strange new puzzles. We will discuss recent results which indicate that most of the matter in the universe takes an exotic ghostly form of "dark matter." The nature of dark matter is unknown, but upcoming experiments at Fermilab and elsewhere may finally unlock its secrets. We will then discuss recent evidence that the universe is not only expanding but is accelerating. This unexpected result seems to imply that a "dark energy" exists which is repulsive and thus counteracts the cosmic effects of gravity. |
