except the waste. I know how to get rid of that though - Send it all to the moon.

If we send that much mass to the moon, it's likely to upset the synchronicity between the moon's orbital and rotational speeds so that we will see those guys who live on the other side.

Without a proper introduction and establishment of diplomatic relations, they may not be inclined to view our spying on them as a friendly action - and who knows what they might do?

They obviously are not interested in contact with us, since they've been hiding from our limited "searches for life signs" on the other side.
