@bobokyo: What the... HELL! LOL! That's current Aizen..
@taichokage: But a casual wristflick from Ichigo was able to completely shatter it, and its pretty obvious that a full-powered swing from PS should be stronger than Ichigo's casual backhand (it destroyed two large mountains with air pressure alone).
As for having enough strength to warp space-time, I'd say that's not really a quantifiable aspect. Even characters like Frieza haven't shown enough strength to warp spacetime, however that doesn't mean Frieza can't break the hado.
