Scott Douglas Jacobsen: We have been talking a lot about new forms of order on and off tape.
Rick Rosner: I addressed the fact that there are different forms of order that look vastly different, like the order of biological life versus the order in the universe. Where every point in the universe has an average redshift versus the rest of the universe, or versus other points in the universe, every point in the universe has an average redshift of the objects near that point.
The objects surrounding a point within 20, 30, 100, a million, light years of a point in the universe when observed from any other point in the universe have an average redshift from whatever point they’re being observed from.
That redshift is going to depend on what point that redshift is being observed from. But the objects, the large objects that are being observed tend to have velocities that are not too far off from the average apparent velocity of that region of the universe.
In other words, everything in the universe appears to be expanding with an expansion or an apparent expansion vector that isn’t too far off the expected expansion vector for that point in the universe. That is, there is a form in the universe.
The universe has largely sorted itself out. Where you can imagine a more compact universe in which stuff is flying every which way, but if you allow enough time to pass, and if you allow the expansion of the objects and their velocities will tend to organize the recessional vectors of every large object, so, you have fewer and fewer collisions over time.
Then everything will have a central explosion like a firework and everything will move in roughly straight lines from the central point. Within the initial bag of explosives, there could have been chaos within the initial deal, where things are burning and flying around with stuff crashing into other stuff.
It is only when you have the collision, the number of collision per unit time declining and then everything appears to be flying out in an orderly fashion. The collisions more early than late, that is a form of order. It is much different than the form of order that you would find in a possum.
They are both forms of order in the universe. I would suggest that all those forms of order fit under or can be fit under an umbrella of increasing order. There are stories to be told that we have not found out yet. We do not have any inkling about how these forms of order on large scales of space and time – how they interact with each other.
But we can look for evidence of local order, of the order that evolves, on planets, say. Maybe, it goes off a planet and starts re-engineering the nearby areas in the solar system or forming non-evolved order.
When evolved life starts making artificial intelligence, artificial intelligence is constructed order. You get another form of order. I believe all these forms of order are potentially important to the story of the overall universe.
We just don’t have an inkling of how far that stuff goes. But we can look for evidence or can, at least, imagine looking for evidence. It shouldn’t be that hard. According to IC, the universe is older than it appears to be.
So, it is easy to make a list of where to look and what to look for, for large objects that might be bigger than the apparent age of the universe. We still need to do that. It is also possible – and some science fiction writers have occasionally written about this on the most superficial level – to imagine a civilization trying to construct a galactic empire.
Star Trek has it. Star Wars has it. I didn’t watch enough Battlestar Galactica. You could imagine human-type galactic empires constructed with the help of a faster than light travel being possible. But it is also possible beyond the really simplistic idea of that kind of empire.
It is the idea that sufficiently advanced civilizations, for their own purposes and perhaps for greater purposes – even without faster than light drive, might take it upon themselves to travel across a galaxy and to develop powerful technologies to stella-form to mess with stars, to galacti-form or mess with galaxies, to cosmo-form or mess with the structure and stuff of the universe in order to raise the probability of its survival on some vastly huge time scale.
For instance, at various times, we have talked about parts of the universe like galaxies and galactic clusters fusing material and running out of material and then burning out, and then falling out of the active center of the universe to be reactivated later.
But let’s say there is some civilization that does not want to do that any longer, and wants to manipulate matter to reduce the possibility of a collapse, if a) IC or something like IC is more accurate than a Big Bang or a solely Big Bang type universe, and if we start to understand what galactic engineering might look like, we might look for indications of it or proof of it.
For example, is the universe more smoothly distributed in its apparent recessional velocities than the apparent history of the universe would indicate? Has there been intentional smoothing? I would assume that observers of the future will look for stuff like that.
That’s pretty much the end.
