Why time travel is a bad idea

Apart from the usual temporal paradox issues. Remember that our earth spins at ~1,600 km/hr while it travels around our sun at ~107,000 km/hr. If this is not fast enough, our whole solar system travels around our galaxy (The Milkyway) at ~828,000 km/hr and the Milkyway moves through the universe at an amazing 2.1 million km/hr. With all this, highspeed spinning and twirling moving 1 minute into the future or past will mean a trip into the vacuum of space or even inside a planet or a collision with an asteroid.
