[QUOTE="Umbran, post: 5697005, member: 177"] You can get to any major hub in the matter of a day. Getting to a backwater town in a remote, difficult area (say, the Andes or Himalayas) will still take most normal folks quite a bit longer. For things off our planet, the scale ramps up to numbers that are meaningless to most folks really quickly. Well, let's see. If you can go 0.1c (one-tenth light speed - fast enough that relativistic effects start becoming noticeable, but still easily comprehensible), you can go from the Sun to Earth in about 80 minutes. You could go from the Earth to Mars in between 40 minutes and 2 hours (depending on orbital positions). You could go from the Earth to Saturn in something between 11 and 14 hours (again, depending on orbital positions). Getting out to Neptune from the inner solar system would take 40 hours or so. Getting out to Pluto from here might take up to 64 hours. The Milky Way has a diameter of roughly 100,000 light years. If you want to be able to get anywhere in the galaxy in a matter of a day or so, you need to be able to go... 30 million times the speed of light? That's 300 million times faster than you need to do the same thing in the solar system - that gives you an idea of the differences in scale. The nearest galaxy is 2.5 million light years away. To get there in a day, you need to be able to go 900 million times the speed of light or so? Call it a round billion times lightspeed. And that's just to reach the nearest galaxy. The visible universe has a radius of 46.5 billion light years. To reach the edge of it in one year, you need to be able to go 46.5 billion times the speed of light. To get to the edge of it in a day, you're talking 17 trillion times lightspeed. [/QUOTE]
