论文摘要
我们表明，超紧凑对象sgr a*阴影的观察到的角直径有利于存在额外的空间尺寸。这不论超紧凑物体的性质，即是虫洞还是黑洞模仿，但具有共同的特征，即它们俩都具有额外的维度。该结果适用于使用KECK和重力协作的质量和距离测量值，以及我们是使用观察到的图像还是观察到的阴影直径。特别是，观察到的阴影的中心值或观察到的图像直径预测了从额外尺寸继承的非零头发。
We show that the observed angular diameter of the shadow of the ultra compact object Sgr A*, favours the existence of an extra spatial dimension. This holds irrespective of the nature of the ultra compact object, i.e., whether it is a wormhole or, a black hole mimicker, but with the common feature that both of them have an extra dimensional origin. This result holds true for the mass and the distance measurements of Sgr A* using both Keck and the Gravity collaborations and whether we use the observed image or, the observed shadow diameter. In particular, the central value of the observed shadow or, the observed image diameter predicts non-zero hairs inherited from the extra dimensions.
