Originally posted by StoicIf you look at those scans, there is no sign of blood or violent effects at all. That is because what is happening to him is more about the changing laws of reality he has to deal with each time he moves through another dimension. He isn't being destroyed, but he has to experience each.
It's funny because it was stated that when Thanos went through the Nexus of Realities that he was being dichotomized, which is indicative of being torn apart more on a mental level than a physical one, while having secondary physical implications, like the ones that happened to Xavier when the Shadow King crushed him on the astral plane making his legs break on the physical plane.
The realities are forcing him to exist in those different states and because he is Thanos, he was able to adapt to the experiences until he could pass through.
