Re: [Utah-astronomy] To call or not to call. That is the question.

Einstein's universal speed limit only applies if you pass through all points between your start and end point. We don't know if extra-dimensional travel is possible, but I wouldn't be arrogant enough to say that it's impossible. I also don't believe that extraterrestrial beings have visited our solar system... that kind of energy expenditure likely wouldn't be wasted on covert visits or joy rides that result in crash landings. As has been stated before, we're already sending out signals. More of them, no matter what the message, won't tip the scales either way. Rich Allen
