A scientist from University of North Carolina states she has mathematical proof that black holes (illustrated) can’t exist. She said it is impossible for stars to collapse and form a singularity. Previously, scientists thought stars larger than the sun collapsed under their own gravity and formed black holes as they died. When a huge star many times the mass of the sun comes to the end of its...
