Been looking at a bit of nuclear and electro-magnetic propulsion technology lately and been thinking about designing concepts for a interstellar spacecraft designed for long-term travel and large populations. 

What are everyone else's opinions on the concept of one day shooting across the stars in search of a habitable exoplanet?

It sounds fun, but in the long long long term the light cone plays into effect...

That would be awesome dude! Just imagine The feeling when the pilot says: "hang on to your hats, this baby is about to go over the light-speed!"

Pheeew! I'd shit gold right there.
