# Unlimited Universe: Can We Explain It?

• aceace
In summary: For instance, we can't understand how a natural number can keep growing forever, but we can understand that 12 is bigger than 11. But when we try to extend that to an infinite number, we run into problems.

Somebody say if you are not there, you don't understand what's happending there.
Is that the same reason that we can't explain why this universe is unlimited just because we can NOT get to the limit of the universe if it does exist.
Anyway, I can't understand something is unlimited, just like a natural number can grow up forever.

As I've said before, there's no such thing as a dumb question if you're really seeking an answer. In this case, I don't think that the human brain is capable of comprehending something like that as a physical structure. Mathematics is the only way to get a handle on it. You can build all of the hypercube models you want to, and still not be able to 'see' the time dimension. Same for a finite, yet unbounded, entity such as the universe. There are too many dimensions to be dealt with by a brain that can only detect 4 of them and see 3.

Do you also have the same problem with linear algebra and infinite series expansion?

That's basically correct. Current physics suggests that the finite speed of light limits what we can say about the universe. That's why we have to make the distinction between an "observable universe" and the entire thing (there are a variety of terms in use).

Practically speaking, I think theorists tend to have the same discomfort with infinities. They make for a nice mathematical tool, but we get worried whenever they seem to show up in real life.

## 1. What is the "Unlimited Universe" theory?

The "Unlimited Universe" theory proposes that the universe is infinite and has no boundaries or edges. This means that the universe extends infinitely in all directions and there is no center or end to it.

## 2. How is the "Unlimited Universe" theory different from the Big Bang theory?

The Big Bang theory suggests that the universe had a beginning and has been expanding since then. The "Unlimited Universe" theory, on the other hand, argues that the universe has always existed and will continue to exist forever. It also does not support the idea of a singularity or single point of origin.

## 3. What evidence supports the "Unlimited Universe" theory?

There are several pieces of evidence that support the idea of an unlimited universe. One is the observation that the universe appears to be homogeneous and isotropic on a large scale, meaning that it looks the same in all directions and locations. Additionally, studies of the cosmic microwave background radiation and the distribution of galaxies also suggest that the universe is infinite.

## 4. Can we ever fully understand the "Unlimited Universe"?

As scientists, our understanding of the universe is constantly evolving as we make new discoveries and advancements. While we may never have a complete and perfect understanding of the "Unlimited Universe", we can continue to expand our knowledge and theories through scientific research and experimentation.

## 5. How does the concept of infinity play a role in the "Unlimited Universe" theory?

The idea of infinity is central to the "Unlimited Universe" theory, as it suggests that the universe has no boundaries or limitations. The concept of infinity can be difficult for our minds to comprehend, but it is essential in understanding the infinite nature of the universe according to this theory.
