So if only 8 percent of the habitable worlds have been created, then that may add a mathematical wrinkle in the Fermi Paradox

We are, in fact, that alien race that conquers the stars while other civilizations are in their infancy?

Or all the possible habitable worlds all currently have alien life living in them. It probably only looks barren for now because we are looking at light rays reflected from that planet that have been coming our way centuries ago. Perhaps, there are many civilizations like ours thinking they're alone when we are all here. Since the sun is about 4.22 light years away from us. Imagine how far back into the past we are seeing those other "habitable" planets.

SpectreX, the sun is not 4.22 light years away; it is 8.3 light *minutes* away. you're probably thinking of Alpha Centauri which is 4.37 light years away

Of course, the degenerate/black-hole era heath death vision of the future depends on a model of cosmology that hasn't yet been fully proven, and may be attributable to negative temperatures in inter-galactic voids distorting light to red-shift, which seems equally as plausible as dark energy expanding the universe.

Oh, my bad. Thanks for the correction Jacob.

That means we only have to wait 200 billion years to find out if their right.

Because we are finite beings with a beginning and an end, people are preoccupied with a 13.5 billion year universe that will end in 100 trillion more... instead of accepting that it has always been in existence.
If theoretically 92% of habitable worlds have yet to be created, that still means there are gazillions that are already in existence, in any number of stages of development.
We can't possibly be alone, and it's conceivable (to me) that beings that can travel through vast distances of space have a reality of time where a thousand of our years are just a blip of half a second...or less. I am becoming more convinced that we are someone's farm project/experiment, and therefore their property. They keep watch on us, and every now and then they come by to see what the silly primitive earthlings are doing, hoping we haven't annihilated ourselves yet.

No, it's not really an answer to the Fermi Paradox. The evidence suggests there's probably lots of Earth-like planets in the Milky Way. Earth-like includes old enough for the evolution of intelligent life. Anything happening in other galaxies is irrelevant. They're all too far away to detect other civilizations.

It seems the scientist of today knows all, when in fact their findings will keep changing until someone finally gets it right.
