Discussion Overview

The discussion revolves around the question of why objects like a computer do not appear to move away from an observer in the context of an expanding universe. It touches on concepts related to cosmology, the nature of expansion, and the implications of redshift observed in distant galaxies.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant, Andy, questions why his computer does not seem to be moving away from him despite the universe's expansion, expressing uncertainty about his understanding of the concept.
  • Andy wonders if the computer is moving away very slowly or if he has misunderstood the concept of an expanding universe.
  • Another participant points out that there are prior discussions on this topic, suggesting that Andy look at previous threads for more information.
  • Andy acknowledges the help he received and expresses regret for not searching for existing discussions before posting.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as it primarily consists of a question and responses without a detailed exploration of the underlying physics involved.

Contextual Notes

There may be limitations in Andy's understanding of the expanding universe and how it applies to local objects, as well as the implications of cosmic expansion versus local gravitational effects.

Hi

Im new here so please be kind :smile: .
I just wondered, since we live in an "expanding" universe, why is my computer not moving away from me as i type this message? Light from most of the stars/galaxies in the sky is redshifted so they are moving away from me (or so I am told), why not my computer? Is it because my computer is actually moving away from me, but just very slowly or have a completely missed the point and not understood the concept of an expanding universe (i think this is probably the case).
Just so you know how to gauge your response, I am an A Level student (UK) and I am going to University this year to study Physics.

Thanks for any help you can give me and remember I am new so don't be too harsh when you tell me i don't have a clue about Physics :smile: .

Thankyou that has helped me loads.
Sorry, i really should have searched before posting.

Thanks for your response anyway :smile:
 
No prob. :smile:
