Could the Universe Be Rotating Instead of Expanding?

Click For Summary

Discussion Overview

The discussion revolves around the concept of the universe's expansion and the hypothesis that it could be rotating instead. Participants explore the implications of this idea within the context of cosmology, questioning how rotation might affect observations of the universe.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant expresses curiosity about the universe's expansion and invites others to share their thoughts.
  • Another participant suggests that the field of cosmology is relevant and recommends reading the current standard model.
  • A participant questions whether the universe could be rotating, proposing that this might create the illusion of expansion.
  • One participant argues that a rotating universe would not match observations and expresses uncertainty about the concept.
  • Another participant counters the rotating universe hypothesis by stating that such rotation would violate isotropy, which is well established in cosmology.
  • A later reply challenges the initial questioner’s approach, suggesting that their ideas lack scientific basis and encouraging them to study established scientific concepts.

Areas of Agreement / Disagreement

Participants express differing views on the possibility of a rotating universe. Some support the idea of expansion while others argue against the feasibility of rotation based on observational evidence. The discussion remains unresolved with multiple competing views present.

Contextual Notes

Participants reference the isotropy of the universe and the need for a scientific basis for claims, indicating limitations in the initial hypotheses presented.

I was wondering because of my personal theories what others thought of the universe expansion.

please help

Cosmology is an entire field devoted to this and other related phenomena. Have you read up on the current standard model? If not I would hit up wikipedia or other online sites and grab a book on it from a local bookstore or from online.

But just about the expansion of space, see here: http://en.wikipedia.org/wiki/Metric_expansion_of_space
 
I've heard of this before, but I believe a rotating universe does not match observations. I'm not real sure about it.

No, if it were rotating, the effect would not produce identical results in all directions, thus violating isotropy, which is well established.

Wildwill, based on this and another post of yours I have to say that it seems that you are just throwing out random ideas with no basis in science. Please read up on real science ... there's a lot of fascinating stuff there and once you've got some basics under your belt you'll be able to ask more meaningful questions.
