Remember, along with orbiting around the Sun at 66,600 miles per hour., the Earth is also rotating on its axis at about 1,070 mph. On top of that, don’t forget our whole solar system is rocketing through space around the center of the Milky Way at around 560,000 mph. On top of that, our galaxy is hurtling through space at around 670,000 mph with respect to our local group of galaxies.
So, bottom line, even if you went back in time just a few seconds, you’re going to be in a VERY different place than when you first achieved 88 mph with your DeLorean. Go back several hundred years, and you are going to need an extremely fast space ship and some good star chart data to find your way back to Earth.
But let’s say you’ve figured all that out. After a quick stop to murder baby Hitler and a few of his top cronies (or at the least bring a wizened Mister Rogers back to give their parents some life lessons to instill in their children), how far back could you go and still be able to communicate effectively in the English speaking world?
