Light reflection from edge of universe

In summary, the conversation discusses the concept of a boundary in the universe due to the pull of gravity. The speaker suggests that light will slow down and return to us, but acknowledges that this may be incorrect. The question is raised about the red shift value of light from stars that have not yet reached the boundary. The conversation ends with a statement that the universe has no boundary or center, and that the idea of an event horizon is speculative.

tif we presume that our finite universe has a boundry. This boundry 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 boundry 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.
 

Related to Light reflection from edge of universe

1. What is light reflection from the edge of the universe?

Light reflection from the edge of the universe refers to the phenomenon of light bouncing off of objects that are located at the very edge of the observable universe. This light has traveled a tremendous distance and can provide valuable information about the early stages of the universe's formation.

2. How far is the edge of the universe?

The edge of the observable universe is estimated to be around 46.5 billion light years away. However, it is important to note that the universe itself may be infinite and therefore does not have a physical edge.

3. Can we see light from the edge of the universe?

Yes, we can see light from the edge of the universe. However, the light that we observe has been traveling for billions of years and may have changed or been distorted along the way. This makes it difficult to accurately determine the exact conditions at the edge of the universe.

4. What can we learn from studying light reflection from the edge of the universe?

Studying light reflection from the edge of the universe can provide valuable insights into the early stages of the universe's formation, including the distribution of matter and the expansion of the universe. It can also help us better understand the properties of light and the laws of physics.

5. How does light reflection from the edge of the universe impact our understanding of the universe?

Light reflection from the edge of the universe is crucial in expanding our knowledge and understanding of the universe. By studying this light, we can gain a better understanding of the history and evolution of the universe and potentially uncover new insights and discoveries about the nature of our universe.
