Abbas Kashani > "In fact, the first solution to Einstein's field equations implies the existence of black holes".

Einstein himself never accepted the notion of "black hole"; nor gravitational wave. These are the concoctions by official science to big-up Einstein's false theories of relativity.

On the question of "Black Hole", Albert Einstein (in whose name this big fraud is promoted) himself in a published paper (link Below) emphatically dismissed the possibility of "Back Holes" even in theory! The following is a copy of his conclusion at the end of this mathematically rich and lengthy publication: "The essential result of this investigation is a clear understanding as to why the "Schwarzschild singularities" do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does not seem to be subject to reasonable doubt that more general cases will have analogous results. The "Schwarzschild singularity" does not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light.

This investigation arose out of discussions the author conducted with Professor H. P. Robertson and with Drs. V. Bargmann and P. Bergmann on the mathematical and physical significance of the Schwarzschild singularity. The problem quite naturally leads to the question, answered by this paper in the negative, as to whether physical models are capable of exhibiting such a singularity." Albert Einstein. A. Einstein, The Annals of Mathematics, Second Series, Vol. 40, No. 4 (Oct., 1939), pp. 922-936

Einstein's theories of relativity and the dark/black cosmic Monsters are Fairy Tales, which have with no relevance to objective reality. Please see the following:

Preliminary results of the dark energy survey, DESI, indicate that dark energy was more prevalent in the early universe, implying a time varying cosmological constant. Placing this variable on the right of general relativity and treating it as a driver of gravitation instead of a constant structural element, it can be shown that gravitational collapse singularities might be avoided.
