“the moon gets knocked out of orbit just a smidge, its gonna play hell on our ocean’s tides...”
Oh much more than that... Our Barycenter could change. That could affect gravity influences on Tectonic plates and could eventually even affect our own orbit and axial pitch. It could affect the Magnetosphere and in turn Atmospheric Cells and weather. It could literally even change how we keep time... there are a whole slue of things that could happen if the Moon was changed from it’s normal...
