Reply #158: I know where you're coming from and there isn't too much we can do about radio signals, but I view

the slab and radio signals as a package deal.

The slab can point them in the right direction, I also believe an intelligent, advanced species capable of interstellar space travel would have superior detection and probably superior linguistic skills to our own.

They wouldn't need to come as close in order to detect, distinguish and analyze natural background radio noise from artificial systematic radio signals.

As I posted elsewhere, I believe it's imperative that we do master space travel, I'm just not for hanging out neon signs as to our location, I would much rather for us to be the discoverers as opposed to the discoverees.
