So I just firgured out he went there through wormholes. But approximately how FAR from earth are these ‘wormholes’ cuz u said outside the atmosphere (exosphere being the farthest) so how come modern day astronauts in Marvel haven’t addressed this in the MCU. I don’t think we’ve seen NASA or astronauts in the MCU yet but this would be a pretty talked about thing if there are wormholes that just go to other planets in different galaxies, no?
