away from the GodForce, but surely Thor didn't need to exert himself like with the Celestials.
Marvel states full power Galactus is the physical equal of Eternity.Celestials proved to be at least on his level, it would require a direct fight like Big G VS Exitar to show what's the ranking, who is above who to me.Cause we got only general principles or not direct instances for judging.Alternate Earth's doesn't count, we talk about 616 universe.
It's been said the Celestials real ebsence reside in hyperspace, that's why IW force fields were able to injure them, but this still doesn't prove the ranking.Considering Galactus was able to absorb the energies from Hyperspace which Hyperstorm was feeding off, we may say that he could just slay the Celestials accessing to the Hyperspace, but to me, it could work with a sinlgle, maybe 2 of them.A host of 5/6 Celestials, considering Big G has his hunger, the biggest plot device after the mighty Batkick, the Supes jobber aura and so goes on, he will be down for the count in the end.
My 2 cents.
