Why does the antipodal tide happen?

Question

It makes sense to me why there is a tide facing the Sun and a sublunar tide, but why is there a tidal bulge on the opposite side of the Earth too?

Answer 1

The center of rotation of the Earth-Moon system is offset from the center of the Earth. It is still within the Earth but closer to the Moon.

So the oceans facing the Moon are gravitationally attracted to the Moon and the oceans opposite are furthest away from the gravitational center of the Earth-Moon system.
