    Edge Universe
AI Thread Summary
The discussion centers on the concept of the universe's edge, questioning whether a finite universe implies a definitive boundary. It is argued that a finite universe does not necessarily have an edge, as explained by Prof. Leonard Susskind. At the observable universe's 'edge,' one would only see objects within the limits set by the universe's age and the finite speed of light. Thus, the observable universe's extent is always relative to the observer's position and time. Ultimately, the universe lacks a true center or edge, challenging traditional notions of boundaries in cosmology.

If the universe is finite then there must be some farthest object or farthest place at the extreme edge of the universe. If that is true and you are standing at that place what would you see? Would you see stars in one direction and black emptiness in the other?

Finite doesn't mean there must be an edge.

Prof. Leonard Susskind explains it well in this lecture:
Start around 1h20'.

 
You've asked these types of questions before. The answer hasn't changed: the universe has no center or edge.
 
At the 'edge' of our observable universe you would only be able to see as far as the age of the universe due to the finite speed of light. So, the distance to the 'edge' of the observable universe is always determined by its age wherever/whenever you happen to be observing it.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
