What Happen To Stars When They Die?

There are so many stories which are associated with researches. A recent study by the scientists has questioned Einstein’s equation.
Researchers have recently gone through some identification and corrected an error that was made while applying an Einstein's equations for modelling the growth of the universe.
Two Universities of Hawaii at Manoa researchers have recently identified and corrected this subtle error.
Physicists assume this usually that a cosmologically large system, for example the universe, is not sensitive to details of these small systems that are contained within it. Kevin Croker who is a postdoctoral research fellow in the Department of Physics and Astronomy, with Joel Weiner who is a faculty member in the Department of Mathematics, have now shown that this assumption can also fail for the small objects which remain after the collapse and explosion of large stars.
Croker said that for 80 years, they have generally operated under these assumptions that the universe, in broad strokes, was unaffected by the particular details of any small region. He also added that it is now known that general relativity can observably connect with collapsed stars and also to the behaviour of the universe as a whole.
Croker and Weiner have also demonstrated that the growth rate in the universe can in future become sensitive to the contribution of such compact objects. Likewise, it is found that the objects themselves have the ability to become linked with the growth of the universe, where gaining or losing energy depends on the objects' compositions. This result is essential since it reveals the unexpected connections that are between cosmological and compact object physics, which in turn results to many new and innovative observational predictions.
One consequence that is attached with this study is that growth rate of the universe delivers information regarding what happens to the stars after their lives end. Astronomers assume that large stars form the black holes after their death, but this is not the only outcome which is possible.
