If the universe had boundaries, what would the outside look like?

The outside is the same as our universe, the universe comes from the big **, belongs to one entity, and it should also have another entity on the outside.

A void. Because before the universe was formed, there was nothingness, so if the universe had a boundary, there would be nothingness outside.

No one has ever seen the boundaries of the universe, but everything has a boundary, whether it is the macrocosm or the microcosm, because one flower is one world. And the world is still material. So outside of the universe, I'm afraid there is another universe.

The universe is infinite! Believe it or not, I've played more easily than put: the earth is me, and then what? The house I live in is the Earth's atmosphere, what is the room I leave from? It's the street, and it just keeps walking ......Who can argue with that?

According to the latest observations, the farthest galaxy that has been observed from us is 13.7 billion light-years. That is, if a beam of light is emitted from the galaxy at a speed of 300,000 kilometers per second, it will take 13.7 billion years to reach Earth. This distance of 13.7 billion light-years is the extent of the universe as we know it today.

To be clear, the extent of the universe as we know it today, or size, is a spherical space centered on the Earth with a radius of 13.7 billion light-years. Of course, the Earth is not really the center of the universe, and the universe is not necessarily a sphere, but we can only understand this extent due to our current observation capabilities.

Therefore, the universe has no boundaries, and our observation ability determines how far we can see, and our observation ability is developing, and the scope of observation is also increasing. However, according to the theory of the universe, the universe is still expanding.

The vast universe is boundless, and its depth is unimaginable, In April 1999, an astronomical research team at the State University of New York in the United States used"Hubble"The immense power of space telescopes. After more than 2 years of careful observation and scientific processing with electronic computers, more than 400 images of celestial objects overlapping in this direction were eliminated"Please"One of the oldest galaxies has emerged, and from the fact that it regresses and expands at the speed of light, it should be at the edge of the universe at 13.7 billion light-years!

The distance of 13.7 billion light-years is incomparable, and even the fastest light would have to travel 13.7 billion years to reach it. It can be seen that this farthest galaxy is also a celestial body shortly after the universe, and it is extremely precious and ancient"Cosmic fossils"Because in exploring the origin and evolution of the universe, the early history of the universe will be of immeasurable significance.

The universe is not infinite, or rather, the narrow universe we live in is not infinite. Its boundaries are still debated in what form they exist, but the idea that "our universe" is not infinite has been largely agreed.

Now there is an argument that space-time is distorted at the edge of the universe, meaning that you can get infinitely close to it, but you can't reach it.

As for the universe in a broad sense, that is, whether the universe outside "our universe" is infinite, this is not clear, just as it is impossible to talk to Xia Worm, the current human science and technology have no understanding of this, and the current research has not yet broken through the scope of our universe.

The universe is infinite, but it is bounded. Hawking's understanding of the universe is like a basketball, you can't find a beginning and an end on the surface, but it is bounded. It's like a lot of astronomy books are covered in it, if you look at Stephen.

Or it can be obtained from the big ** theory that our universe is still expanding, and galaxies are still regressing from each other, that is, the universe we know is still expanding, extending, and expanding, but it has not yet reached its end.

I don't know if there are borders.

If there is a boundary, then there is no "outside the boundary", because the universe includes everything, and if the so-called outside the boundary is discovered one day, then it can only mean that the boundary of the past is not a real boundary, and the newly discovered boundary becomes inside the boundary.

The universe in my mind is boundless, without beginning or end, and there is no distinction between inside and outside and always. It is in a cyclical, never-ending process.

In my possible answer, the universe has an edge, but for now, the farthest galaxy that scientists can observe is the edge of the universe, and since the universe occurs at a source point, then it will have a total point, and then rewind to the source point, or it will disappear without a trace, but anyway, since it is still purely at the edge, no matter how far away it is, and the theory of relativity also says that time, space, and matter are linked

No. The universe is all space, and the universe is all time. The universe is the sum of all time and space.

You can only ask questions, but you can't answer them, because we belong to one person in the universe.

In the end, the universe has no boundary, so it can't reach the end, but there is no boundary in the end, and outside the boundary is the universe, and the outside is still the universe.

For example, does dividing 1 by 0 have a result? What is the number of results if there is a result? How about dividing this result by 0?

You can ask this question, but it doesn't make sense to ask it.

The big ** view is that there is no time and space before the big ** (and therefore there is no concept of before the big **, let alone the concept of outside), so there is no "being" that can be defined by time and space. If anything, it has no size, no place, no age.

I suddenly remembered the Tao Te Ching.

Theoretically, the universe is infinite. The universe is slowly expanding, expanding to a certain extent, shrinking, and then **, expanding again, and then in a cyclical cycle.

But in fact, depending on how big your heart is, how big your heart is (how big you understand), how big the universe is.

The universe also has boundaries. Outside the universe, we may see nothingness, or we may see another "anti-universe". We all know that the vast universe has always been one of the goals of our continuous exploration for human beings in tens of thousands of years of development.

There are no wonders in the universe;

Once upon a time, the ancients, who lacked various scientific detection tools, were using the perspective of mythology to understand the universe; Later, modern science came into being, and in the 21st century, we look at the universe from a scientific perspective.

How big is the observable universe? It's about 93 billion light-years in diameter. For humanity, this is, of course, an indisputably astronomical figure.

After all, we haven't even flown out of the solar system, which is only about a light-year in diameter. Compared to the vast universe, it is a drop in the ocean.

Of course, there are also many people who wonder what magnificent and fantastic scenes outside the universe cannot be explored. Some scholars believe that beyond the universe, there is nothingness, no time, and no space; Mr. Stephen Hawking, the great physicist of this century, is a staunch supporter of this view.

Hawking also gave this "nothingness" a scientific name, called "Hawking Chaos". There is no time and space, chaos; It sounds somewhat similar to the Buddhist "nirvana". Of course, there are also some fans of superstring theory, who believe that there are countless universes beyond the universe.

For example, Wayne, a professor in the Department of Astronomy at Columbia University in the United States. In his speech in 2017, he pointed out that the complete universe has 11 dimensions, and the world we live in is only a three-dimensional structure.

In the three-dimensional space, there are two universes, and beyond the boundaries of the existing universe, there is an "anti-universe" that is very different from our timeline; If we can travel through the wormhole to the high-dimensional space, we will see endless "parallel universes".

And in these "high-dimensional spaces", there are those extraterrestrial super civilizations that live.

The universe has no boundaries, and the complex universe is constantly expanding.

The shape of the universe is still unknown, and human beings are boldly imagining. Some people say that the universe is actually a small cell of such a creature similar to a human being, while others say that the universe is a program or a small original made by a computer creature with higher intelligence than humans.

There are also speculations that the universe is actually an electron, that the universe is something much smaller than an electron, that the universe does not exist at all, or that the universe is intangible.

There are also speculations that our universe lives in a large space called "hyperspace". In hyperspace, there are many universes, and the energy of hyperspace is conserved and very huge. Whenever the energy of one universe rises, the energy of his neighboring universe falls.

In every place in the universe, the energy is different, there is positive energy, there is dark energy, and there is no energy.

At present, the more popular is the big ** theory.

According to the big ** theory, the history of the universe can be represented as a closed surface body with an open right end, as shown in the figure on the right. At the center of the left is the singularity, which extends 13.7 billion light-years to the right. From left to right:

Singularity, 400,000 years of initial expansion, nearly 400 million years of dark periods, emergence of stars, galaxies and planetary developments, accelerated expansion of dark matter and dark energy.

What is it like outside the universe can only be relied on speculation and imagination. Human knowledge can only be confined to the universe.

Because nothing in the universe can escape.

DAO universe, so I can't understand what's going on outside the universe.

The universe is once great.

And still is.

** Said to form some of the matter that formed the planet.

Some formed galaxies.

Some evolved into stars.

Some planets have thrived with life.

The universe has no boundaries.

Because it's spreading.

The universe is just a process.

An act. What's happening.

Arguably. It was a great one.

Because in a moment.

She created the earth. Created human beings.

Although this ** is an instant.

But measure this moment in human time.

Probably hundreds of millions of years.

At least until now, in 2008, it shows no signs of stopping.

I don't think the galaxy will stop without him.

Because if you use Newton's brother's laws to demonstrate.

An object can have two conditions without any external force.

One is stillness. One is to do a uniform linear motion forever.

I think the universe belongs to the latter species.

If the distance of ** is measured in one unit.

That is"Light years"

The universe also has a boundary, because although the universe is very vast, it still has a boundary, and beyond the boundary there may be a space like a black hole, or it may be the next unknown universe.

At present, there is no boundary, because the universe that can be known to mankind is getting bigger and bigger, and there is evidence that the universe is still expanding, there is no end, and no one can know what is beyond the boundary of the universe, it may be dark matter.

The universe that has been discovered is 92 billion light-years, but the universe is much larger than that. Outside the universe may be empty space, without any matter, and the universe will gradually occupy this space as it expands, but this is only a theory.
