Speaking of the time chamber ... and I´m aware that I´m trying to bring the logic again ... how exactly did Thin Boo and SS3 Gotenks escape from it by blowing a whole in the space-time continuum, using a strong attack? Pretty sure Blue Goku´s Kamehameha is far strong than whatever Boo and Gotenks did back then. He should be ripping spacetime all the time :>
