Data derived from a balloon-borne probe of the early Universe provides strong evidence that the Universe is flat and not open.  The data is also consistent with the idea that the theorized cosmological constant, a form of countergravitational "dark energy" thought to fill the universe, is helping drive the never-ending expansion of the Universe. Also, a sidebar explains how scientists are able to explore the enigma of the Universe's beginning and its ongoing evolution using "the message from the beginning of time."

Determining the origin of ancient artifacts helps define the  relationships and influences between old-world peoples. For instance, correlating pottery fragments found in excavations with where the pottery was made illuminates the trade and cultural contacts among ancient settlements. Unfortunately, in culturally complex areas where various settlements were making and trading similar wares, the standard methods of archaeology -- excavating and comparing decorative styles and materials -- are not always sufficient. This is where new archaeological tools borrowed from the world of nuclear physics come in.
