IPARRAGUIRRE, Lorenzo M.. Black holes and the freezing of time. Rev. enseñ. fís. [online]. 2022, vol.34, n.1, pp.51-60. ISSN 0326-7091.  http://dx.doi.org/10.55767/2451.6007.v34.n1.37943.

In this work some very curious and little divulgated aspects of the hypothetical radial fall of a material particle in one of these objects are examined, making them available to Physics teachers with the elementary knowledge of Especial Relativity correspond ing to their standard training. For this the necessary concepts are presented, it is shown how to operate and reason with them, and it is exemplified with some basic calculations that allow the concepts to be anchored in concrete objects.

Keywords : Relativity; Black hole; Geodesic; Gravitation; Curved space time.
