In braneworld gravity models with a finite anti-de Sitter space (AdS) curvature in the extra dimension, the AdS/conformal field theory correspondence leads to a prediction for the lifetime of astrophysical black holes that is significantly smaller than the Hubble time, for asymptotic curvatures that are consistent with current experiments. Using the recent measurements of the position, three-dimensional spatial velocity, and mass of the black hole XTE J1118+480, I calculate a lower limit on its kinematic age of > or =11 Myr (95% confidence). This translates into an upper limit for the asymptotic AdS curvature in the extra dimensions of <0.08 mm, which significantly improves the limit obtained by table top experiments of sub mm gravity.
在额外维度具有有限反德西特空间（AdS）曲率的膜世界引力模型中，对于与当前实验一致的渐近曲率，AdS/共形场论对应关系给出了一个关于天体物理黑洞寿命的预测，该预测显著小于哈勃时间。利用对黑洞XTE J1118 + 480的位置、三维空间速度和质量的最新测量结果，我计算出其运动学年龄的下限≥11 Myr（95%置信度）。这转化为额外维度中渐近AdS曲率的上限<0.08毫米，这显著改进了通过亚毫米引力桌面实验获得的极限。
