The LHB (and its connection to the Nice model) goes quite far in explaining the size of Mars, the water content of Earth and Venus, the distribution of the asteroids ... what about all that evidence?
- cbkeller 7y agoNot my exact area of expertise, but my two cents would be that the model space is sufficiently vast and underconstrained that there are likely an infinitude of equally allowable models that could also explain these features without an LHB. Since the Nice model was specifically developed to explain the LHB [1], using it as evidence for the LHB seems a bit circular.
