Scientists have been left baffled by a mysterious celestial object so bright that physics dictates it should have exploded.
As it's pulled by the object's intense gravity, the material heats up and radiates light. The more matter that falls toward the object, the brighter it is. But there's a catch.
At a certain point, so much matter is being pulled in that the radiation it's emitting should be able to overwhelm the power of the gravity from the massive object. That means at some point, the radiation from the matter should push it away, and it should stop falling in. But if it's not falling in, the matter shouldn't be radiating, which means the object shouldn't be that bright. Hence the Eddington limit.M82 X-2 is achieving the impossible
Because of the Eddington limit, scientists have questioned whether the ULX's brightness was indeed caused by enormous amounts of material falling into it. One theory, for instance, is that strong cosmic winds concentrated all the material into a cone. In this theory, the cone would be pointed toward Earth, which would create a beam of light that would look much brighter to us than if the material was scattered evenly around the ULX.in the Messier 82 galaxy, put the cone theory to rest.
