Destroying a planet doesn't necessarily implies ripping it apart.
And you are wrong. It is stated in a DE source that Darth Sidious had limitations in use of Force Storm (Wormhole) power because he would loose control at a certain level.

So yeah, wrong on all accounts, try again.
Even if Luke Skywalker's opinion is taken at face value, it implies that the referred Force power can be produced on such a scale that it can consume an entire world. However, Darth Sidious never conjured a Force Storm (Wormhole) large enough to consume an entire planet, he did not had such potential.
