Schwarzschild Naked Singularity Creation
In the Schwarzschild metrics (Plank units):
$$ds^2=-\left(1-\frac{2m}{r}\right)dt^2+\left(1-\frac{2m}{r}\right)^{-1}dr^2+r^2\left(d\theta^2+\sin^{2}\theta d\phi^{2}\right),$$ we can have a Black Hole (...

If the weak energy condition is violated, can the area of the event horizon decrease?
The second law of black hole mechanics asserts
$$\text{WCC} + \text{WEC}\Longrightarrow\delta A \geq 0 \tag{1}$$
where WCC = weak cosmic censorship, WEC = weak energy condition and A = event ...

Can BMS Supertranslations Make a Black Hole Naked?
I recently learned that the BMS supertranslations actually add hairs to black holes and physically change the metric. In such a scenario, I am very curious to know if the black hole can be overcharged ...

Why Do Extremal Black Holes Not Radiate?
This might be a "metaphysical" question with no actual physics content and if such is the case then I apologize. Actually, to figure out whether or not it is an actual physics question is one of the ...
