A revisit of the problems of Abhas Mitra's Eternally Collapsing Object

We critically review here the concepts which gave rise to the Eternally Collapsing Object (ECO) paradigm over
almost 22 years. All the mathematical analysis will be dealt here to conclude the proofs required for the ECO paradigm
to begin with is ad-hoc. First part in rejecting black holes always considers the possibility of formation of trapped
surfaces so we will begin our work by looking into “non-occurrence of trapped surfaces” then we analyze Dr. Mitra’s
indirect claim regarding how R = 0 (inside a black hole) could also be treated as another coordinate singularity!
After that, we review if indeed his another claim about “mass of Schwarzschild black hole being zero” is right or not.
Do black holes really exist or they are just a fairy tale made by physicists to elude us into fiction? And are these
so-called “Black Holes”, actually black hole or indeed as Mitra likes to call them “Eternally Collapsing Object” or
ECO. Are ECOs really a true alternative to Black Holes? The analysis presented here will show us, why ECOs are
baseless can not really a solution to black hole problem
