Comment Pit Stop... (Score 1) 1015
I have said this for years! Imagine you've been on a very long cross-country drive. You come across a small town. What are your priorities? Get gas, Get food, go to the bathroom and dump your trash. A basic pit stop.
Well this is exactly the case with interstellar travel. It isn't easy! You're limited by the speed of light. To get from one system to the next takes a long time. And when they get here they're gonna do the same thing... To get "gas" they're gonna drain of the sun of all its hydrogen. Food... Us. All of it. All the plants, all the animals all the humans... It's a very, very long trip to the next system; gonna need more than a snack to tie them over. The only thing they're gonna leave behind is their trash.
We do not want to meet an alien race because all it is going to mean to them is a pit stop.
