Let me just say that to argue that at a singularity (division by zero) some variables go to „infinity“ would cause considerable problems for a student in the first semester of mathematics.
Very terse and detailed explanation. However the diagram that depicts the Schwarzshild metric is not 100 % correct. The mass is represented by a point, but it should be represented by a vertical line. Indeed, it is not a 2 spatial dimensions diagram but a space-time diagram. The mass is a point mass, that is correct, but it is stationary and in the r-t diagram it should be drawn as a vertical line. It is easy indeed to fall in the trap: the mass is a point mass, so I draw it as a point.
The elucidation and understanding of theoretical mathematical expressions presented in these lectures are genuinely splendid.
Thank you again. I am finally in awe of the metric tensor. Einstein had a genius intuition.
Now, I have to agree this guy is an excellent EDUCATOR
Thank you! Your analysis is very good and accurate
Thank you sir. Excellent videos and voice over.
an object cannot go to r < Rs because it is outside of the spacetime. at r=Rs time could also be inverted.
isn’t there a misinterpretation of small r ? Schwarzschlid first article indicates (r3 + alpha3)^1/3

Muy bueno. Para enterarme de lo que dice, utilizo el traductor de Google.
