Title: Spacetime "expansion" as an increase in underlying complexity Post by: M Benesi on June 13, 2017, 04:27:44 PM I was thinking about the whole fractal geometry of the path I was running yesterday- thinking that if I added in all the zigzags (using accurate GPS), I'd increase the total measured distance of the run by ~ 10%.
This led to me thinking about Spacetime expansion- that perhaps the geometry of spacetime increases complexity over time as more particles are added to it. This would mean there are more zigzags in any straight path, which would increase the total distance a "particle" or "quantum field" had to traverse to get from point A to point B. Are there any articles on this concept, what is the name of the concept, etc.... <-standard questions. Thanks!

I think we call this entanglement.

though I wouldn't say that there are more particles created and as far as I understand this is also what cosmology says: s. https://www.quora.com/How-many-particles-are-there-in-the-universe Quote "The commonly accepted answer for the number of particles in the observable universe is 10^80. This number would include the total of the number of protons, neutrons and electron Now most of the photons in our universe are the photons from the cosmic microwave background radiation and it is estimated that there are 10^9 photons for every particle in the universe so that would make 10^89photons in the universe." Particles are resused over and over. And if this happens in a fractal way, things become complex. I think the ultimate increase of complexity in spacetime is life, us, our brains... And doesn't time kind of fold as well as space? the world has been speeding up exponentially.

Nice sidefact: Statistically a few of the the atoms that make up your brain have been part of Sockrates brain 2500 years ago.

Nice sidefact: Statistically a few of the the atoms that make up your brain have been part of Sockrates brain 2500 years ago. I think that time only changes it's rate with big changes in gravity. It's possible that there is confusion between the rates of events with time itself changing it's rate. While we know that time is not the Newtonian "absolute" that it was once believed to be, I don't think it is changing inherently. Events of significance may be happening with greater frequency, but I think that is independent of time (space-time) itself. And what was that about my brain again? I knew I was old, but didn't think I was 2500 years old already! I could have sworn I was only two hundred and six! Maybe time *is* speeding up after all...

Geologs sayd that with development of rock types had increased twice. Of corse with development of humans it increased even more.

I was under the impression that neutrino production increases the particle count- so there is a steady increase in the amount of particles in the universe over time, which would increase the complexity of the underlying spacetime structure (if it is not completely smooth).
