Instead of making a new infinity gauntlet out of Stark nanotechnology, why didn’t they just venture back to Nidavellir and forge a second infinity gauntlet like the original one? That way, the gauntlet can absorb more of the radiation and Hulk wouldn’t be as damaged as we saw him in the movie.

Better yet, why not grab the original gauntlet off of Thanos’s dead body and repair it in Nidavellir before having Hulk use it again after the time heist?

Either way, Hulk would be better off and not as damaged.
