What do you see at the edge of the universe?

In summary, if the universe is finite, it does not necessarily have an edge. Despite this, at the extreme edge of the observable universe, you would only be able to see as far as the age of the universe due to the finite speed of light. Therefore, there is no specific place where you would see stars in one direction and black emptiness in the other. The universe has no center or edge, as explained by Prof. Leonard Susskind in his lecture.

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.

1. What is the edge of the universe?

The edge of the universe is not a physical boundary or a visible line. It is the limit of the observable universe, which is the farthest distance from which light can reach us. Beyond this limit, the expansion of the universe is so rapid that light cannot travel fast enough to reach us.

2. Is the universe infinite?

The current scientific consensus is that the universe is infinite in size. However, due to the limitations of our technology and understanding, we can only observe a small portion of the universe. Therefore, it is possible that there could be more beyond what we can see.

3. What do we know about the edge of the universe?

Scientists have calculated the approximate distance to the edge of the observable universe to be around 46 billion light years away. This means that the light we receive from objects at the edge of the universe has been traveling for 46 billion years to reach us.

4. Can we ever reach the edge of the universe?

Due to the expansion of the universe and the limitations of our technology, it is highly unlikely that we will ever be able to physically reach the edge of the universe. However, it is possible that future advances in technology may allow us to observe and learn more about the edge of the universe.

5. What lies beyond the edge of the universe?

Since the edge of the universe is the limit of our observable universe, we do not know what lies beyond it. It could be more of the same universe, or it could be something completely different. This is still a topic of research and speculation in the scientific community.
