The general theory of relativity showed that gravitation is equivalent to
distortion of space, and predicted the existence of black holes (BHs), from
which even light cannot escape. Time halts on the event horizon. And, space
and time exchanges their natures inside a BH.
On another front, according to the quantum field theory, the substance of an
elementary particle is considered to be a kind of local wave traveling in the
space where we live. Inside a BH, where nature of the space is fundamentally
different, it's unreasonable to consider that the quantum field theory
established outside the BH can be applied. (In the first place, it's
questionable whether the same kinds of elementary particles as those in the
space outside a BH can exist inside the BH.)
Consequently, the gravitation theory can be considered to be more universalistic
than the established quantum field theory.
Then, I wonder whether it really makes sense to construct a quantum gravitation
theory which is to build a gravitational extension on the base of the quantum
field theory.
Is there any crucial reasoning to believe that the gravitation is to be
quantized?
