Something to Consider Before Travelling in Time
Maybe Isaac Asimov can calm you down. An excerpt from his book, The End of Eternity:
He had not doubted precision pin-pointing in Time-travel since his Cubhood days. He remembered himself then, facing Educator Yarrow seriously, saying, “But Earth moves about the Sun, and the Sun moves about the Galactic Center and the Galaxy moves too. If you started from some point on Earth, and move downwhen a hundred years, you’ll be in empty space, because it will take a hundred years for Earth to reach that point.” (Those were the days when he still referred to a Century as a “hundred years.”)
And Educator Yarrow had snapped back, “You don’t separate Time from space. Moving through Time, you share Earth’s motions. Or do you believe that a bird flying through the air whiffs out into space because the Earth is hurrying around the Sun at eighteen miles a second and vanishes from under the creature?”
