Hello everybody, I was watching a documentary about black holes the other day and I noticed something odd. General Relativity is said to break down when you apply the mathematics on a singularity. In this case, the center of the black hole. The radius of a singularity would be 0. Now there was my problem. I was learned that the smallest possible length, is Planck's length (1.616199 × 10-35) meters. I guess that the radius of a singularity would have to be the shortest possible length. What is your opinion on this? And where did I (probably) make my mistake in my 'logic'? Thanks in advance!
