The study of cosmology is theoretical astrophysics at the largest scales.
Because it is a very broad subject, astrophysicists typically apply many disciplines of physics including, but not limited to, mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.
They use a wide variety of tools which include analytical models (for example, polytropes to approximate the behaviors of a star) and computational numerical simulations.
Mottola and Pawel Mazur, an astrophysicist at the University of South Carolina, have their own theory about what fl holes are, and it has nothing to do with infinite energy.
While no astronomer or astrophysicist can say for sure what dark energy is, mathematical calculations and theoretical data have shown it to be a real concept, and it is generally accepted by the scientific community, Mottola said.
As a gravistar is created, the phase shift would discharge energy in the form of big quantities of gamma rays, which would explain the phenomenon of gamma ray bursts, something astrophysicists haven't been able to explain with the standard models.
