利用太阳系实验探测基本引力的机会
Opportunities for Probing Fundamental Gravity with Solar System Experiments
摘要:
最近“暗能量“的发现挑战了爱因斯坦的广义相对论作为我们宏观宇宙的完整模型。从理论的角度来看,挑战甚至更大:广义相对论显然没有延伸到量子力学占主导地位的非常小的地方。因此,基础物理模型需要进行一些重大的修改。我们必须进行更深入的探索,以约束和激发这一所需的新物理学。在太阳系领域,我们可以有效地探测与广义相对论预测的微小偏差:技术现在提供了广泛的机会,可以进行比以前更精确的实验。我们描述了相关的理论背景和更精确的太阳系实验的机会。
英文摘要:
The recent discovery of "dark energy" has challenged Einstein's general theory of relativity as a complete model for our macroscopic universe. From a theoretical view, the challenge is even stronger: general relativity clearly does not extend to the very small, where quantum mechanics holds sway. Fundamental physics models thus require some major revisions. We must explore deeper to both constrain and inspire this needed new physics. In the realm of the solar-system, we can effectively probe for small deviations from the predictions of general relativity: Technology now offers a wide range of opportunities to pursue experiments with accuracies orders of magnitude better than yet achieved. We describe both the relevant theoretical backgrounds and the opportunities for far more accurate solar system experiments.
