Here's a little bit of fun. Voyager 1 is about to leave our Solar System (ish). Here's a calculator designed to inform you of how long it would take to reach those outer limits using your vehicle of choice. 

Cool, that thing is moving so quick 

Not something you would want to use for a "quick trip" to the chemist, though.

I rather suspect you might be in danger of becoming chemistry if you tried to go at that speed Dave 

Voyager is only (he says) going at 19km/s. Light speed is nearly 300,000 km/s. It's the acceleration that makes you chemistry. And maybe the radiation.

Space, big isn't it.
