The Space Problem

Be careful when using time machines. You'll probably find yourself in deep space.

I’m a fan of time travel movies, but one problem never addressed by time travel stories is the space problem.

As described here,

  • The surface of the earth at the equator moves at roughly 1,000 miles per hour.
  • The earth moves around the sun at about 67,000 miles per hour.
  • The solar system moves around the center of our galaxy at about 490,000 miles per hour.
  • The galaxies in our neighborhood are also rushing at a speed of nearly 1,000 kilometers per second towards a structure called the Great Attractor.

Something to think about when you step into that time machine. You’ll most likely find yourself in deep space.
