Space/Science » in reply to Re: Nick & ETI - Could another large planet in a nearby orbit -

Possible - but the case I am thinking about

is where the tectonic forces are generated by a large planet in the next orbit in or out from the primary star -

Of course, another element that hs to be examined when estimating the likelihood of ETI is accretion, in other words impact events. Despite the claims of some here, we do not have enough data to model that process even for our own solar system with any degree of accuracy - EP
