@eddz99: put goku inside a star. tell me what happens. oh that's right he gets owned.
EDIT goku's energy being felt across the universe proves nothing considering the dragon ball verse is made up of 4 small galaxies. also it could be felt only to those who knew KI. goku powering up barely shaked the earth.
Cell transforming made a earthquake more powerful than ssj3 goku did ( That shows that ssj3 was controlling it to buy time most probably ) , ssj3 goku was focusing all his energy inside him, the shaking earth thing was just a side effect also, http://www.animevice.com/dragon-ball/10-1/galaxies-that-exist-infinitely-a-break/97-340792/#2 , The galaxies of the mortal universe are infinite , and they are 12 universes, the realm of the supreme kai are outside that.
The put goku inside a star thing is a baseless statement, when goku went against frieza, he wasn't even affected by lava , frieza also tanked a planet explosion without ki, a planet explosion's energy > / = a star
I can also say that dbz chars can increase their resistance with ki to that kind of things but i guess i will do that later.
