There are two questions in Questionland right now that don't have a (good) answer. Can you help?

Can anyone recommend a better quality costume shop?

How long would it take something man made to travel 20 light years with existing technology?

Edit: Actually, there was a good answer to the latter question. Kip Waddle said: "'From A Distance' by Bette Midler, traveled 20 light years since its release in 1991. So the the answer is; 20 years."

I thought he was kidding. But, as he pointed out after I implied his answer wasn't good, "The fact is, radio waves are man made and our transmissions have already reached the newly found planet. Valid answer."

I stand corrected. I got a C in science. I'm sorry.
