I have to agree here. I've been following celestial dynamics news for many
years now and the consensus seems to be moving away from a model of planets
forming where they sit (orbit) to a much more chaotic one where planets tend
That said, Velikovsky's theory is not wrong because it has planets moving
around, but because of the time scales involved (as mcsmith points out,
though a few 100K years is very quick when you think about it:) and also
because of his evidence, some of which includes myths such as Biblical
passages. Not that the Bible is to be totally discounted as evidence, but
it certainly is not what I would my base my theory of the formation of solar
system on.:) (If we were discussing religion or philology or Jewish
history, then the Bible might be a good piece of evidence.)
Back to the emerging model, it seems confirmed somewhat weakly by extrasolar
planets and also by Neptune's affect on transneptunian objects like Pluto.
(A issue of _American Scientist_ from last year covers the latter problem.)
The resonance orbits of the latter seemed best explained by this.
Other _additive_ lines of evidence, too, lend more credence to this idea --
some of which are detailed in the BBC article, such as that there just does
not seem to be that much stuff out there to form Uranus and Neptune
according to current estimates of what the early solar system was like.
