Posted November 19, 2008 Imagine if Earth was as big as Antares... There would probably be no way of communicating across such a vast space, you wouldn't be able to travel over much of the place. In fact there would probably be 50-100 worlds in one planet. Share this post Link to post Share on other sites

Posted November 20, 2008 I read somewhere (probably Wiki) that if the Milky Way galaxy was reduced to 130km in diameter, then our solar system would account for 2mm of it. Over 31 years ago, the Voyager 1 probe left Earth to fly past Pluto and try to reach interstellar space. As of late 2008, it has just reached the Heliosheath (so it's not actually out of our solar system yet) and has travelled a mere 1/600th of a light year. The closest star system to us is over 4 light years away. When you consider that it's estimated that the universe consists of hundreds of billions of galaxies, you get a rough idea of just how insignificant we are. We're not even a speck.

Well, I'm comfortable with the thought that, in time, those probes may reach other forms of life. And 31 years is not so bad for such a distance. I maybe would have gladly sacrificed my life to be on such a mission if only to just see the wonders. Share this post Link to post Share on other sites
Posted November 20, 2008 Voyager 1 isn't going that fast anyway. We can do much better. Share this post Link to post Share on other sites
Posted November 20, 2008 Is it such a good idea though? To announce our presence to an alien civilisation we know nothing about? Anyway, read this, good old copy and paste. The nearest known star to the Sun is Proxima Centauri, which is 4.23 light-years away. The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600th of a light-year in 30 years and is currently moving at 1/18000 the speed of light. At this rate, a journey to Proxima Centauri would take 72,000 years. Of course, this mission was not specifically intended to travel fast to the stars, and current technology could do much better. The travel time could be reduced to a few millennia using lightsails, or to a century or less using nuclear pulse propulsion (Orion). A better understanding of the vastness of the interstellar distance to one of the closest stars to the sun, Alpha Centauri A (a sun-like star), can be obtained by scaling down the earth-sun distance (150,000,000 km) to one meter. On this scale the distance to that star would be 271 kilometers or about 169 miles. No current technology can propel a craft fast enough to reach other stars in under 50 years' time. Current theories of physics indicate that it is impossible to travel faster than light within a flat region of space-time, and suggest that if it were possible, it might also be possible to build a time machine using similar methods. Additionally, given that information can travel no faster than the speed of light, it can take decades just to receive information from such a probe once it reaches its destination, and even longer if not automatically programmed to carry out actions upon arrival. However, special relativity offers the possibility of shortening the travel time: if a starship with sufficiently advanced engines could reach velocities approaching the speed of light, relativistic time dilation would make the voyage much shorter for the traveler. However, it would still take many years of elapsed time as viewed by the people remaining on Earth, and upon returning to Earth, the travelers would find that far more time had elapsed on Earth than had for them So basically, we'd never see anything in our lifetime anyway, but who knows what advances will be made in the future.

Posted November 20, 2008 But we advance technologically very quickly. So i would say every 10 years on Earth shaves away 10,000 years from that 72,000 long journey. Share this post Link to post Share on other sites
