The universe

As i said on the nanotech post we have alot to explore in this vast universe, but how you ask yourself well the only thing that comes to my head is a big transporter between worlds like a Stargate but its a little impossible, but, a spaceship it is not impossible infact cientists have been working on ships to explore the Solar system, there is only one problem: Gravity, on a spaceship so people can walk or do something normal like we do it in Earth, its called Artificial Gravity, but the only way to produce it is by building a spaceship spining so it could simulate gravity, butwhat if wanted to build a bigger spaceship it could not be a giant hovering disk, that is a bit ugly on my opinion well i hope over the years we could make a ship good enough to explore AT LEAST the galaxy, part of it, and of course find new beeings or aliens whatever you want to call them, but allways remember: Never alone...
