His opinion is off the mark. That's plain to anyone.
It is impossible to stay in Black Hole.
Black Hole is not a hole.
Black Hole is the place where gravity is so powerful that even light can't escape.
The gravity is so powerful that particle compactions occur.
In accordance with Periodic table of the Elements, a matter changes to its next matter in Black Hole.
C (carbon)--->Si (silicon)--->Ge (germanium)--->Su (tin)--->Pb (lead)
At last, every matter will change to H(hydrogen).
A gravitational shock waves is the sound of the outflow of hydrogen from Black Hole.
Periodic table of the Elements expresses the contents of Black Hole.
The words of “If you feel you are in a black hole," is wrong.
A man or a machine can not exist in Black Hole.
They can not keep their bodies at the level of atomic element.
Then, the man cannot have a chance to feel "I'm in a black hole".
In Black Hole, adiabatic compressive heating occurs.
Then the inside of Black Hole has high temperature.
So a man will never go to the inside of Black Hole in the future.
