The most surprising discovery in cosmology since Edwin Hubble observed the expansion of the Universe is that the rate of this expansion is accelerating. This either signals that a mysterious Dark Energy dominates the energy density of the Universe, or that our understanding of gravity on large scales is incorrect. The implications for physics and astrophysics are profound, and refining our understanding requires new higher-quality measurements of the expansion rate of the Universe as a function of time.

自埃德温·哈勃观测到宇宙膨胀以来，宇宙学中最令人惊讶的发现是这种膨胀的速度正在加速。 这要么表明一种神秘的暗能量支配着宇宙的能量密度，要么表明我们对大尺度引力的理解是不正确的。 对物理学和天体物理学的影响是深远的，完善我们的理解需要新的更高质量的测量宇宙膨胀率作为时间的函数。
