Light reflection from edge of universe

Click For Summary

Discussion Overview

The discussion revolves around the concept of light reflection in relation to the hypothetical boundary of the universe. Participants explore ideas about the universe's structure, the nature of light, and the implications of gravitational effects on light behavior, including redshift. The scope includes theoretical considerations and speculative reasoning.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that if the universe has a boundary due to gravity, light could slow down and return, raising questions about the redshift of light from stars moving away.
  • Another participant asserts that there is no boundary to the universe.
  • Some participants argue that the universe lacks an edge or center, challenging the initial premise.
  • A different viewpoint introduces the idea of an event horizon as a potential "edge," though this remains speculative.
  • One participant expresses concern that the discussion is becoming overly speculative without grounding in established concepts.

Areas of Agreement / Disagreement

Participants do not reach a consensus; multiple competing views regarding the existence of a boundary or edge to the universe remain unresolved.

Contextual Notes

Limitations include the speculative nature of the claims, dependence on definitions of boundaries and edges, and unresolved implications of gravitational effects on light.

Who May Find This Useful

Individuals interested in cosmology, theoretical physics, and the nature of light and gravity may find this discussion relevant.

tif we presume that our finite universe has a boundary. This boundary is due to the pull of gravity. Light will slow down and then come back to us. 'i may be absolutely wrong in this'. My question is that the light we see will be from the stars surface that doesn't face us and star moving away from us as it hasnt reached the boundary yet. What will be the red shift value of this light.

There is no boundary!
 
The universe has no edge or "center".
 
i guess it has event horizon that is like an edge
 
This is turning into speculation piling on more speculation.
