Thanks to Einstein’s pesky relativity, time doesn’t play fair across planets—clocks on Mars tick faster because the Red Planet’s gravity is wimpy compared to Earth’s. Scientists just crunched the numbers: Martian days gain about 477 microseconds daily, with wobbles from planetary neighbors. This tiny speedup could mess with future rover sync-ups or Mars GPS, forcing us to create “Mars Standard Time” so our interplanetary Zoom calls don’t lag eternally.
