Smallest known blackhole found

NASA recently found the smallest known blackhole in our universe. The diameter is 15 miles and has a mass of 3.8 times that of the sun. The finding answers the many times asked question of what the smallest possible size of a black hole is. The discovery was made using NASA's Rossi X-Ray Timing Explorer satellite. Although tiny, small black holes exert a force beyond that of larger black holes. This finding is crucial for understanding how matter behaves under extraordinarily high density.
