Mass Dispersion of Observable Universe

Click For Summary

Discussion Overview

The discussion revolves around the concept of mass dispersion in the observable universe and the implications of observing galaxies from different positions within it. Participants explore whether mass distribution is uniform across different sections of the observable universe and the effects of residing in a recently formed galaxy on the perception of the universe's edge.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions if the mass of equal 3-D sections of the observable universe would be equal when observed from Earth.
  • Another participant suggests that galaxies observed at the edge of the observable universe are not younger than the Milky Way, as they are seen from billions of years in the past.
  • A participant expresses interest in the dynamics of an expanding universe and whether the expansion or curvature makes every observed universe appear the same.
  • There is a claim that the most recently formed galaxies are at the center of the universe, with the assertion that everything is at its own center from its perspective.
  • One participant challenges the notion of an "edge" to the universe, stating that the Big Bang was not an explosion from a specific point in space.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the universe's edge and the implications of mass distribution. There is no consensus on whether the observable universe can be uniformly divided or if the concept of an edge is valid.

Contextual Notes

Participants reference concepts such as the expansion of the universe and the curvature of space, but these ideas remain underexplored and are not fully defined within the discussion.

Does anyone know of any data regarding mass dispersion around Earth?

That is to ask (more toward my interest), if the observable universe was broken into equal 3-D sections like "North to Northeast" "NE to E" "E to SE" and so on... would the mass of each section observed from Earth be equal, for all intents and purposes?

Does anyone have any theories as to what the affect would be of having the observed universe of a planet residing in the youngest (most recently formed) galaxy on the "edge" of the universe?

(1) yes
(2) I think you're confusing apparent age of galaxies with actual age. The galaxies that we see on the edge of our OU are just as old as ours is, it's just that we SEE them from 13+billion years in the past, so right now, if we could be instantaneously transported to those galaxies, we'd see a U that looks just like the one we see from Earth (other that local variations). To them the milky way looks like it's young.
 
Well, I have a problem with asking a question that isn't really my question, so for that I apologize. But actually I wasn't talking about galaxies at the edge of our observable universe, though that is interesting in itself because I'm curious to know our universal position.

My interest in asking that question was about the dynamic of an expanding universe and if the expansion of the universe is so fast or its curvature (something I don't understand, still) or some other phenomenon actually makes every observed universe the same.

Because in my mind if we transplanted one of our telescopes into orbit of a planet in the most recently formed galaxy and it could see objects that were billions of years old in all directions, then it seems plausible that it could see the edge of universe (whatever it may look like).

Of course that leads me to another interesting idea: whatever the expansion of the universe entails, how close to the edge can galaxies actually form?

The centre. As is everything else.

There is no such thing.

The most recently formed galaxies are in the center of the universe. As Dave said, EVERYTHING is (and what he means is "from it's own point of view") at the center of the universe. There is no edge.

You seem to be making THE fundamental mistake in cosmology of believing that the "big bang" was an explosion that happened at some point in space and moved out from there. It was not and did not. You need to read more VERY basic cosmology. I do not mean that to be rude, it's just an observation.
