|So LAZY ! Except that the whole Earth is moving around the Sun
as well as rotating...
Then again, the entire Solar System is orbiting the center of the galaxy at about 138 miles every second. That would get you from London to Sydney in just over a minute, the Moon in half an hour, Mars in 3 days, Pluto in a little under a year. But it's still nowhere near enough to explore the galaxy. Even travelling at that speed for 70 years, you'd only travel about 1% of the distance to Alpha Centauri - actually reaching our nearest star would take about 6,000 years (in case you're wondering, Voyager I is currently moving at a paltry 17 km/s away from the Sun; bullets move at a pathetic 1 km/s).
Conclusion : space is big. As a wise man once said, really big. You just won't believe how vastly hugely mindbogglingly big it is... Also, everyone on Earth is moving much faster than a speeding bullet. I love science.
