    Motion Time
AI Thread Summary
The discussion explores the relationship between time and motion in the context of an expanding universe. It questions whether time can be separated from motion, suggesting that time may be a potential for movement that expands ahead of measurable motion. The idea is proposed that the visible universe cannot be considered a single duration of time, as parts of time remain unfilled by motion. Additionally, the concept of dark energy is examined as a potential factor influencing the expansion rate of the universe, which exceeds the speed of light. Overall, the conversation seeks to understand the implications of time as a potential for motion on a universal scale.

Can we split time from motion? I would think not, Space as we measure it is still expanding at a rate that is faster than light; if this is correct then we need to at least have some understanding as to why and I would think that time in the sense of it being a potential for movement, is expanding ahead of all motion we measure as space. Would this be a fair statement?

Can we call our visible universe a single duration of time? I would think not, unless we take into account the part of time that motion has not yet filled.

Would the concept of time being potential movement, remembering that motion already fills part of that potential, fit on the universal scale? Can, this concept be used to explain why the universe could be expanding faster than light? Could dark energy be the potential, both larger and smaller, between that of motion with its speed limit of light, and time's expanding "potential for motion” because relative motion has not reached it yet?
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
