We describe a simple approach for a possible connection between the exterior and interior of black-holes. According to our result, the Schwarzschild radius determines a [Formula: see text]-dimensional sphere that separates two worlds: the exterior, where ordinary matter moves with velocities less than the light velocity, and the interior, where tachyons move with velocities greater than the light velocity. Moreover, we find a geometric map in the complex plane that connects ordinary matter with faster than light particles. Motivated by these results, we also find that the exterior and the interior structures of black-holes can be unified in a world of [Formula: see text]-dimensions. Finally, we comment about the possibility that superluminal particles in the interior of a black-hole may provide an alternative solution of the rotation curves of spiral galaxies.

朝着黑洞的外部/内部对应

我们描述了一种简单的方法来建立黑洞外部和内部之间的可能联系。根据我们的结果，史瓦西半径决定了一个 [公式：见文本] 维球体，它将两个世界分开：外部，普通物质以低于光速的速度运动，而内部，速子以大于光速的速度运动。光速。此外，我们在复平面中发现了一张几何图，它将普通物质与比光速更快的粒子连接起来。受这些结果的启发，我们还发现黑洞的外部和内部结构可以统一在一个[公式：见文本]-维度的世界中。最后，
