The universe doesn't have volume from outside?

The Universe encompasses all of space and time, so there is no space outside of it. Therefore, it is impossible to view the universe from the outside. As for the shape of the universe, current scientific theories suggest that it is either flat or curved, but it is still infinite in size. Therefore, neither you nor your friend is correct in this discussion. In summary, there is no way to view the universe from the outside and its shape does not determine its size.

A friend and I have been debating a topic for the last few days and I would really like a more informed opinion on the discussion.

My friend says that IF you could, some how, see the universe from the outside and it appears that the universe is a finite flat, spherical shape, or other shape then it obviously isn't infinite.

I say, because the universe is space itself, its apparent volume outside of space is irrelevant because it's not taking up any space. For all we know, it could look like a tiny sparkle to us on the outside and be the giant infinite universe we know on the inside. It may look finite on the outside but could never stop getting smaller.

Who is closer to correct, here? The information you give us is invaluable and highly treasured.

Your discussion has no scientific basis. It is unclear what you would even mean by "viewing the universe from outside". You cannot go outside the universe.

By definition there is no outside of the Universe.

What does it mean when scientists say that the universe has no volume from outside?

When scientists say that the universe has no volume from outside, they mean that the universe has no boundary or edge. This concept is based on the idea that the universe is infinite and has no end or edge that can be measured. It is also referred to as the "boundary problem" in cosmology.

How do scientists measure the volume of the universe?

Currently, scientists do not have a way to accurately measure the volume of the entire universe. Due to the concept of the universe having no boundary, it is impossible to determine its exact size. However, scientists use techniques such as observing the expansion of the universe and studying the distribution of matter to estimate its size.

Does the lack of volume from outside mean that the universe is empty?

No, the lack of volume from outside does not mean that the universe is empty. In fact, the universe is filled with various forms of matter and energy, such as galaxies, stars, and dark matter. It is just that the universe has no edge or boundary that can be measured or observed.

If the universe has no edge, does that mean it goes on forever?

It is currently unknown whether the universe goes on forever or has an end. The concept of the universe having no edge does suggest that it could be infinite, but this is still a topic of debate among scientists. Future advancements in technology and research may provide more insights into the size and structure of the universe.

Does the lack of volume from outside have any implications for the beginning of the universe?

The lack of volume from outside does not have any direct implications for the beginning of the universe. However, it does raise questions about the concept of a "Big Bang" or the singularity that is believed to have started the expansion of the universe. It also challenges traditional ideas about the nature of space and time. Further research and understanding of the universe may shed more light on these topics.
