I'm not a comic book junkie (staying on top of comic books is probably the only thing more time consuming or demanding than staying on top of politics), but can Superman resist Force-based immobilization? What if Palpatine (or Luke or Yoda or anyone else sufficiently powerful) simply moves to hold Superman still with the Force?
Planets, stars, and black holes can't hold Superman still.
Again, the Respect thread should quickly put down the idea that anyone - or everyone, under most VF circumstances - in the SWU can do anything to Superman against his will.
This is not up for debate. Do not bring it up again, or I will be forced to actually post in your forum.
