At the start of Avengers: Endgame, Iron Man is at the brink of death and "thousands of light years from the nearest 7-11" when Captain Marvel shows up. It appears like Captain Marvel carries neither food nor oxygen, yet brings the spaceship to Earth before Iron Man dies.

Question: To rescue Iron Man (and Nebula), how long did it take Captain Marvel to travel to Earth?

Captain Marvel doesn't use the bifrost nor the space stone, she just carries the spaceship back to Earth. She would have to do this rather quickly to ensure Iron Man gets back in time to eat an "American cheeseburger".

1 Answer 1


Less than a day

Firstly, Tony says in his message to Pepper that it's Day 22 and that the oxygen will run out "tomorrow morning".

Then, when Captain Marvel rescues the ship and brings it to Earth, Rhodey explains that

...it's been 23 days since Thanos came to Earth".

This indicates that Captain Marvel made the trip in 12 to 24 hours.

  • Is the message to Pepper what alerted them that Tony was still alive? The message is never broadcast so I doubt it, as that would mean that the message somehow travels faster than lightspeed. May 6, 2019 at 8:17

    I don't understand how you came to the 12 to 24 hours conclusion. Is there any reason why it couldn't be 11 hours or 25 hours for example?

    Also, she has Kree tech on her suit - presumably it's capable of scanning a wide area of space for a disabled ship. (I mean, heck, it can turn a 90's era pager into an FTL communicator, what can't it do?) May 6, 2019 at 13:00

    She already had contact with the Avengers core team via the post-credit scene in her origin movie. It's likely she's been looking for any sign of known superheroes left. May 6, 2019 at 16:13
