Hi, just wanted to ask a question since there's loads of info spinning about in an empty universe,

If the Oort cloud is spherically symmetrical about the sun, does that mean that it did not take part in the rotational alignment of the planets etc, when the planets started to form and the kinetics settled a bit? And if it did, does this mean that loads of ice formed after the the stability apeared and became unconnected to the inner solar system, and alot of water could have been present in an earlier state of the solar system that subsequently boiled off into deep space since the gravitational force is so weak?
