A finite universe would help me understand the nature of expansion of the universe. I have always had trouble understanding expansion other than
galaxies "moving" away from each other. I just couldnt use reason to understand an infinite universe expanding. I have never had a satifying answer.
Probably my own mental capacity but, how would the universe itself expand if it is everyrhing? It just seems like empty space would gain matter. The
empty space would have to be part of the universe or else we need a new definition I would think.
The fact that multiverses could exist without conscious observors also seems unimportant to conscious life. Pondering something unobservable seems
Foam theory I believe uses a background lower dimensional null space. Imagine the universe as a bubble, one of many probabilistic universes, expanding
into a pure "vacuum" of unknown properties. It would expand like a field, fields can move faster than light. Dependant on universe proximity to other
universes, our universe would probably expand for a finite period of time, but due to present expansion rates, we may not be able to see the edge as
it could be moving faster than light. That boundary we may never be able to get past, unless we understand the properties of the initial particle, in
which case we should be able to traverse the multiverse.
It's also possible in foam theory to travel through the weakest bridge point. Eventually, as the bubble-like universes expand to the point of touching
boundaries, if that can even happen, the bubbles would change geometry from bubbles to cubes. Once this happens, the weak points would be the areas
furthest distant from the cube centre, or the corners. The problem is that of statistical probabilities in regards to the makeup of adjoining
universes. If the laws that govern those universes are slightly different, one could end up in something extremely hostile.
Back to expansion and fields, if you have a 1000 Watt laser and move it in an arc pointed at the moon and your arc path is 6" moving at C, the speed
of the laser's red dot across the surface of the moon will be many many times C. This can also be done with magnetic fields, I have an adiabatic
reactor and the magnetic field can be rotated around the chamber at 1.25C, I've never taken it higher, not because I can't, but rather because of what
the math predicts. So, can the universe as a field expand faster than the speed of light? Yes it can, which would mean that like a singularity, the
escape velocity is greater than what physical law allows, at least until expansion stops, which it may never or may become a static construct abutted
against other universes of similar expansion "pressure."
On finding a way out, alive, I would look at temporal proxies as a stepping stone to understand and initial particle that produces all other
particles. You see, if you set laws governing one particle and replicate that particle, it is easier to test all probabilistic universes by slightly
altering the laws of all other initiating particles. There are 4 or 5 basic adjustments that involve the strong and weak forces, gravity, etc. I could
go a lot deeper into this, string theory, m theory, etc, but I think it would get away from trying to understand all of this.
So simply imagine that the universe is a sealed jar with a finite amount of particles. We have a sufficiently large computer outside the jar that can
measure every particle, their energy and interactions at any given time. Because the computer is sufficiently powerful, it can perform temporally
related backwards and forwards computations predicting the positions, characteristics and energy of all particles at any point in time with zero
uncertainty, after all the computer is outside the jar. Ergo, the computer can predict the entire "life" of the contents of the jar, this make the
contents of the jar predetermined. The system is deterministic, all future events within the jar are predictable.
If you substitute "jar" with "universe" we have literal equivalency. Scientists are beginning to gain some consensus on the deterministic nature of
the universe. If it is this way, there can be no free will. If there is no free will and everything can be predicted from "outside the system" then we
must be outside the system physically but operational within the system through some form of "tethering" which might be predicated on Bose Einstein
like technology. Which means, we are simply as I said before, riders in meat puppet buses, with no control, we follow a script from which we may never
I hope I wrote this properly, lol.
