Atheists and Agnostics risk infinite loss for no gain

But why would we not be getting radio waves?
Most civilizations would be emitting them for at least 100 years.

This should answer Grace's question (assuming she takes the time to read this.)

"While it’s interesting to imagine how far our radio signals have traveled into space, it’s extremely unlikely that an alien will be able to catch the latest episode of ‘I Love Lucy’. This is thanks to the inverse square law. In Layman’s term, it’s a form of signal degradation.

As radio signals leave earth, they propagate out in a wave form. Just like dropping a stone in a lake, the waves diffuse or “spread out” over distance thanks to the exponentially larger area they must encompass. The area can be calculated by multiplying length times width which is why we measure it in square units – square centimeters, square miles, etc. This means that the further away from the source, the more square units of area a signal has to ‘illuminate’.inverse square law

Another way to think of it, is that the strength of a radio signal will be only 1/4 as great once you are twice the distance from the source. At ten times the distance, the strength of the signal would only be one hundredth as great.

Because of this inverse square law, all of our radio signals become indistinguishable from background noise at around a few light-years from earth. For a civilization only a couple hundred light-years away, trying to listen to our broadcasts would be like trying to detect the small ripple from a pebble dropped in the pacific ocean off the coast of California – from Japan."

So there you go, Grace, why we'll never hear a radio signal from space.

Do a little research before you ask a question, please.
