Accelerating expansion of the universe, expansion of the partial universe, contraction of the partial universe, neither expansion nor contraction of the partial universe, Hubble's law, black hole
One of the reasons for 2011 Nobel Prize for physics is "for the discovery
of the accelerating expansion of the universe through observations of distant
supernovae". But "the accelerating expansion of the universe" is debatable.
Through mathematical derivation, according to Hubble's law, the values of far away
distance, far away speed, far away acceleration of a galaxy, and the force acted on
this galaxy are all the exponential functions of time, these reach the unreasonable
conclusions: as time tends to infinity, all of these values will tend to infinity too.
Due to the observation of distance is limited, at most we can say: "partial universe
is in the state of expansion (including accelerating expansion)." In addition, partial
universe (such as the area nearby a black hole) is in the state of contraction.
Therefore the correct conclusion is that there exist at least seven states of
accelerating expansion and contraction and the like in the universe, namely "partial
universe is in the state of accelerating expansion, partial universe is accelerating
contraction, partial universe is uniform expansion, partial universe is uniform
contraction, partial universe is decelerating expansion, partial universe is
decelerating contraction, and partial universe is neither expansion nor
