"Straw_hat_goofy has addressed the unconventional passage of time on Sakaar, but I realized there's actually another major instance of timefoolery in Thor: Ragnarok. Doctor Strange incapacitates Loki by temporarily incarcerating him in an interdimensional pocket reality, and during that period, Loki falls for a total of three minutes and 38 seconds of screentime. If we take him at his word that he experienced thirty minutes of freefall from his perspective, then that time dilation works out to a Lorentz factor of 8.257. Interestingly, this is not all that different from the Time Cell technology that the Time Variance Authority uses to force Loki to relive a temporal loop of Lady Sif's retribution against him for cutting her hair in episode four of Loki. Full credit to @dreadpiratedad for the word 'timefoolery'."
