Research is proposed that can make an important contribution to the question: Do neutrinos have mass? The answer to this question is important to our understanding of our Sun and other stars, which are prolific emitters of neutrinos, to cosmological questions about the existence of dark matter, thought to make up must of the universe, and to particle physics in understanding the relationship of the neutrino to other elementary particles. If neutrinos have mass, the known three types of neutrinos can oscillate, one into another, given enough time- depending on their energy. In this case the produced neutrinos have sufficient time to oscillate, traveling 730 km. through the earth from Fermilab to a detector equipped mine (Soudan) in Minnesota.

有人提出研究可以对这个问题做出重要贡献：中微子有质量吗？ 这个问题的答案对于我们理解太阳和其他恒星（它们是中微子的大量发射体）、关于暗物质存在的宇宙学问题（被认为是宇宙的组成部分）以及粒子物理学中理解中微子与其他基本粒子的关系都很重要。 如果中微子有质量，已知的三种类型的中微子可以振荡，一个到另一个，给予足够的时间-取决于它们的能量。 在这种情况下，产生的中微子有足够的时间振荡，行程730公里。从费米实验室穿过地球到达明尼苏达州的一个装有探测器的矿井（苏丹）。
