Even reading these lines, the universe is expanding at a rapid pace. You are not in the same place you were when you started reading this article. From this perspective The workings of the universe are truly fascinating.

This question naturally leads us to the next question: there are so many planets, stars and galaxies. What is the universe expanding into? After all, everything we see or know should extend to something else, right? It is not so easy to answer the question when it comes to the universe.

What is the universe expanding into?

It is really difficult to answer this question because we are talking about a question that our knowledge has a hard time answering. But of course science has an answer to that. If we give this answer as short as possible, the universe actually nothing expands in it we conclude.

The galaxies in the universe are actually extremely static. However, as time passes, the distances between galaxies increase. What is moving at this point is not the galaxies. The universe is expanding, opening up the existing space more. This shows that galaxies are moving away from each other in our 3D perspective. Maybe the outside of the universe really exists, but we have to go outside the 3rd dimension to observe it.

Imagine the universe as a constantly inflating balloon.

If we imagine the universe as a balloon, it is the result of all the stars and clusters of galaxies in it. dots on the inflatable balloon we see that it is. As the balloon inflates, these points move away from each other. What actually misleads people here lies in the use of the term “expansion” for objects to move away. In fact, the universe is not expanding completely. Instead, it bends like a balloon.

By this definition, the universe does not have to expand into anything. universe one yawn as a whole continues. However, we know that this answer also raises other questions and does not provide a complete answer.

As eyes in the universe, we cannot see beyond the universe.

Even if we assume in the beginning that the general size of the universe is infinite, even if we yawn. in an infinite measure We can say yes, but things can change if the universe has a finite dimension.

If the observable universe has a finite dimension, it may be correct to think that there is something “outside the universe”. Unfortunately, we are running out of answers at this point. We’re in It is impossible for us to perceive anything outside the universe. Because the laws we use apply to our universe. If there’s anything other than that, we can’t answer it with our own science.

Space is not just a vacuum.

We have to think of space, which performs movements such as bending and stretching, as a much more complex place. As we mentioned in the content, we wrote about where the big bang started, basically everything started at one point. The size that was at that first point was the entire universe, and the size that is now billions of light years away is also the entire universe. Our current science shows us that the universe doesn’t necessarily have to expand into something, but that we may be able to observe beyond the universe in the future.
