ABSTRACT: Based on
general relativity, J. R. Oppenheimer proved that massive celestial bodies may
collapse into singular black holes with infinite densities. By analyzing the
original paper of Oppenheimer, this paper reveals that the calculations had a
series and serious of mistakes. The basic problem is that the calculation
supposes that the density of celestial body does not change with space-time coordinates.
The density is firstly assumed invariable with space coordinates and then it is
assumed invariable with time. But at last, the conclusion that the density of a
celestial body becomes infinity is deduced. The premise contradicts with conclusion.
In fact, there is no restriction on the initial density and radius for celestial
body in the calculation. According to the calculation results of Oppenheimer, a
cloud of thin gas may also collapse into singular black hole under the action
of gravity. The calculations neglect great rotating speeds of massive and high density
celestial bodies which would make them falling apart rather than collapsing
into singularities. Because we do not know the function relations that material
densities depend on space-time coordinates in advance, there exists the
rationality problem of procedure using the Einstein’s equation of gravity field
to calculate material collapse. Besides these physical problems, the
calculation of Oppenheimer also has some obvious mistakes in mathematics.
Another improved method to calculate massive celestial body’s collapse also has
similar problems. The results are also unreliable. The conclusion of this paper
is that up to now general relativity actually has not proved that massive
celestial bodies may collapse into singularity black holes.
