Sort of similar to the Great Filter theory, but applied to time travel technology.

You can use the cosmic microwave background as a universal reference frame. Relative to that we move at about 370 km/s, depending on the time of the year.

Now I'm hurting my head by thinking about traveling faster than 370 km/s in the opposite direction to Earth...

For reference: Voyager 1 is traveling at 17 km/s away from the sun. The Parker Solar Probe should reach 191 km/s but will be flying towards the sun.
