As I see it, there are 3 types of civilizations that humans might recognize as intelligent. Anything above #3 is by its very nature,
1. Pre-radio. Any civilization incapable of at least radio transmission is essentially invisible. In the near future humans will be able to image
Earth sized planets and get a sense of what sort of chemistry is going on there. That might betray hydrocarbon industrialization that was typical on
Earth just before the 20th century, but it's a long shot. The Milky Way galaxy could be overflowing with such planets and humans would not know
2. Earth clones. An exact clone of Earth as it is now, literally in every detail, would be invisible to humans here, even if orbiting a neighboring
star. Even if through some magic human beings knew exactly where to look, SETI's Allen Telescope Array would not see another clone of Earth on its
interstellar doorstep. The Milky Way galaxy could have billions of exact clones of Earth and humans would not know it. The detection technology is not
quite there yet.
3. Humans x^y. An advanced civilization goes silent in its communication event horizon. Electronics get faster and use less power as they progress.
Such a civilization goes dark to human attempts at detection.
White Elephant Physics
It is obvious that physics is missing a great deal of understanding. Over 90% of the observable universe is simply missing. Dark energy, dark matter,
and the White Elephant that is the singularity of the Big Bang should be a clue in the Fermi Paradox. If string or M theory are correct, there are
several unseen physical dimensions to the universe. In principle, the birth of this universe was a one-way event, according to current human
understanding. If a truly advanced civilization is able to engineer its own universe, such a process might be a one-way migration. Super civilizations
may simply drop out of our universe, never able to return.
Meaning of Life
Biology is 100% fatal. No matter what advancement is made, nothing beats entropy and thermodynamics. This universe is running down and is going to die
a cold dark death. If a civilization jumps from one planet to another, it is only delaying the inevitable. If such a civilization takes over an entire
galaxy, replacing indigenous populations, eventually that civilization has to fight itself for diminishing returns. Again, the inevitable conclusion
is fatal. The only way out is to ditch biology and leave this dying universe behind.
Advanced civilizations that hang around are not detectable by human beings. The physics that they employ is far beyond human understanding. They are
mature enough to know that every living thing takes its own path, like a biologist that watches a predator kill its prey, and possibly even die out.
If a race dies out, it is meant to do so, and something else will take its place. Such civilizations engage those that attain their peer status, with
some luck and a lot of work, humans may get there someday. I would not expect the gift of a black monolith or some sort of cosmic Rosetta Stone.
Rather, like obtaining a cell phone allows communication with another person with a cell phone, inventing advanced communication technology using
presently unknown physics will open a channel in itself.
Meaning of Everything
Ask not what the universe can do for you; ask what you are to the universe. Nature can not build an iPod or a Corvette without a biological entity as
intermediary. Intelligent biological beings are transient structures in what may be a system of energy evolution. It may be that certain types of
universes can only come to be through extreme forms of pandimensional intelligence, far beyond the capability of mere biochemical life. Universes
external to this one may employ structures that have no analog here. Gravity, electromagnetism, etc., may not exist and reality there may have no
correlation to experience here. ET may simply change context.
