Unlike Steve, though, if the MCU ever decides to release a movie set decades or even centuries in the future, there’s the potential for Carol to appear and either still look the same or only slightly older.
Most aliens in the MCU have much longer lifespans than humans, and now we can count Carol among them.
She may not live as long as someone like Thor, but Carol could continue leaving a big impact on this superhero universe when most of the other heroes around now have passed.
Similar to when Steve Rogers was awakened after almost 70 years on ice, it will be interesting to see Carol back on Earth both reuniting with people from her past who are now much older and acclimating to how times have changed since she was last home, although I doubt this will be explored in-depth during Avengers: Endgame since that movie has a lot on its plate.
