What would happen if Alpha Centauri A, B and Promixa Centauri were cubes?
Hmm, that makes sense. Do you think the Earth's magnetosphere could be affected if these stars suddenly turned into cubes?
It's unlikely that the Earth's magnetosphere would be directly affected, as these objects are still many light years away. However, if the stars were to suddenly disappear, there could be some indirect effects on the magnetosphere and on planetary systems that orbit them.
