Infinite volume of noncommutative black hole wrapped by finite surface
/ Zhang, Baocheng ; You, Li
The volume of a black hole under noncommutative spacetime background is found to be infinite, in contradiction with the surface area of a black hole, or its Bekensteinâ€“Hawking (BH) entropy, which is wellknown to be finite. [...]
