(22,077 posts)are still unaware of. Although we've made giant leaps in knowing far more about the universe over the last 100 years (and especially accelerating during the last 25 years), we don't know everything. Even here on Earth, we don't even know more than a tiny fraction of our own oceans (in the depths). We only been to the Moon several times and never physically to any other planets within our own solar system. Hubble gave us an opening to the universe never before seen, and it's been wonderful.
Although we knowledgeable about the physics of how things are constructed, we are still babes in the woods, still. Medicine, and the art of constructing tailor-made medicines and / or devices, we just begun on this path and have made some headway.
Point being, we just touched the surface, and probably really truly searched a tiny, tiny, tiny fraction of the universe, for any kind of communications (mostly electromagnetic in nature), and the limited amount of ground-based satellite dishes available for such searches are limited, and as a matter of fact, funded by others outside the government (one of the founders of Apple or Microsoft, I think is heavily involved). Other methods of communications have been discussed, perhaps optical and / or quantum entanglement, etc.
I dream of the day when we finally communicate (communications to/from other intelligences), are we that naïve to believe that we're the only ones? I sometimes wonder, however, w/ the way our government has been in the past whether or not if communications has happened (seem to go berserk w/ denying UFOs and the like, perhaps too much so, why?). Do we really know for sure if not? I don't necessarily trust some elements of our government (need to know basis and all of that garbage).
Perhaps it could be a good thing if the government is hiding this, look at the history of how some cultures, when meeting for the first time, destroyed or absorbed the other culture entirely. Look at our own history of exploration, the Indians in 1492, being discovered by Columbus, eventually being absorbed or destroyed, the Mayans by the Spanish, etc.
