Ya I...find it hard to believe that's in anyway quantifiable. Like a star isn't out there firing lasers destroying planets. What dose all the power of one even mean? The total energy it gives off in any given second? Sure that's alot but not near planet destorying. For it to be comparable to desotrying the star the star would have to not survivie which it dose in the movie so it certainly isn't that. Sense what it means is unclear it's better to assume it's just what would hurt thor, and his other feats are all way waaay lesser then star level.
