Do Black Holes Exist? Physicist 'Shocked' To Find No Evidence For Black Hole Formation

Black holes are thought to form when massive stars collapse in on themselves and create gravitational vacuums from which even light can't escape. However, if a collapsing star were to lose too much mass during its destruction, it would no longer have the density necessary to become a black hole. That's the crux of a new study from University of North Carolina at Chapel Hill physicist Laura Mersini-Houghton.
