New Horizons spacecraft 'alters theory of planet formation'

https://www.bbc.co.uk/news/science-environment-51295365

Scientists say they have "decisively" overturned the prevailing theory of how planets in our Solar System formed.

"The established view is that material violently crashed together to form ever larger clumps until they became worlds.

New results suggest the process was less catastrophic - with matter gently clumping together instead.
"


Always assuming the NASA people aren't "fakin' it" of course; for "the grant money" etc. ;)

My bold.

Can't say I like the unnecessary inclusion of politics in this.
The theory is at odds with how the earth's moon formed : https://en.wikipedia.org/wiki/Giant-impact_hypothesis

Not necessarily, the theory doesn't say that all 'large bodies' have to be formed like that.
