  We present here a very simple, short and new proof which shows that no
trapped surface is ever formed in spherical gravitational collapse of isolated
bodies. Although this derivation is of purely mathematical nature and without
any assumption, it is shown, in the Appendix, that, physically, trapped
surfaces do not form in order that the 3 speed of the fluid as measured by an
observer at a fixed circumference coordinate $R$ (a scalar), is less than the
speed of light $c$. The consequence of this result is that, mathematically,
even if there would be Schwarzschild Black Holes, they would have unique
gravitational mass M=0. Recall that Schwazschild BHs may be considered as a
special case of rotating Kerr BHs with rotation parameter a=0. If one would
derive the Boyer-Lindquist metric [1] in a straight forward manner by using the
Backlund transformation[2], one would obtain a= M sin phi where phi is the
azimuth angle. This relation demands that BHs have unique mass M=0 (along with
a=0) which in turn confirms that there cannot be any trapped surface in
realistic gravitational collapse where the fluid has real pressure and density.
Since there is no trapped surface and no horizon there is no Information
Paradox in the first place.
