I am wondering, if your time machine was also a spaceship, when you jumped back, say, 50 years: how far would you need to travel to make it back to Earth from where you are in space if you left tomorrow (May, 29th 2025)?

Considering the solar system is rotating around the center of the Milky Way at ~450,000 miles per hour, 50 years would have you some 197 billion miles from Earth. This is about 13x the current distance of Voyager 1 (15.6 billion miles).

Shiiiiiit.

Hope your time machine has an FTL drive. 😩
