How is space growing?

Is space growing faster than light?

Where are you going to grow up?

What's out there?

Starting, the story of the growth of space. It is written in simple language, the real scenario is much more complex, I will write when the general relativity is fully understood.

1.

We’ve all seen graph paper. Suppose a 2D graph paper has one dot at a time. At one time that graph paper was small. Growing up now. Is growing in such a way that it is growing between any two points in a row. Before it was 1 mm, then it was two mm.

Space is just such a graph paper. It's 2D or, not even 3DO, it's 4D with time. This graph paper called Space was unimaginably small during the Big Bang. After a while it grows very fast, that time is called inflation. Still growing, but not as fast as inflation.

All places are equally but not getting bigger. Mass space tries to shorten time. And the dark energy of space time tries to pull it bigger. Then space cannot be large enough for the density of mass inside the solar system. Even within the same galaxy, the same galaxy cluster, space cannot be large. But the huge gap between the two galaxy clusters will allow Dark Energy to be able to expand the space. For the convenience of calculation, we assume that each cluster is the dot of our graph paper. They are moving away from each other.

A graph paper has no real center. I can draw a graph at any point along the origin. So is space. The center can be taken at any point of it. The distance between any two points equidistant from this graph paper is increasing at a fairly equal rate.

2.

Now hold, many points along the X axis. 1, 2, 3, 4, 5 6. Earlier the distance between 1 and 2 was 1 mm, the distance between 1 and 3 was 2 mm, like this.

1 second later. The distance between 1 and 2 is 2 mm, the distance between 2 and 3 is 2 mm. This means that the distance between 1 and 3 is 4 mm.

After 2 seconds, the distance between 1 and 2 will be 3 mm, the distance between 1 and 3 will be 8 mm.

That means,

Although the distances between two points are not increasing at a very high rate, but the farther the dots are, the higher the distance between them. If so, one day or another I will find a point that is moving away from me at a higher speed of light to expand the space.

Coming from here, space is getting bigger than light. That's not just the time for inflation, it's still happening. That is not the violation of relativity. According to relativity, no one can travel through space-time at the speed of light, but space-time itself can grow at any speed.

The Big Bang happened everywhere. It happened in this place too. Graph paper used to be small, now it is big. The farther we look in any direction, the more we see the past. Let's look at the Big Bang at some point. I don't really see that. The Universe was filled with opaque plasma material after the Big Bang, not seen on its side. Since millions of years after the Big Bang this screen became lighter, photons could come. Everywhere we look we see photons. This is called indirect evidence of the Big Bang. Named Cosmic Microwave Background Radiation. Arno Pangeas won the Nobel Prize for his discovery of this thing.

Since the farther we look, the farther we look at the past, there is a limit to what we can see. The Big Bang occurred approximately 13.6 billion years ago, and the last opaque plasma screen we see is also approximately this time. But we don't see it 13.7 billion light years away. Because the space is getting bigger. The current location of this place is actually 46 billion light years away, not 13.6. This sphere of 48 billion light years is called the Observable Universe. This is probably the smallest part of the total universe.

We do not know whether the total universe is infinite. The bright light of the searchlight later on the head of the dancer dancing on the stage. Its thick black darkness all around. So is our visible universe. That too is a very small part of the whole universe.

Somewhere farther away from this visible universe is moving away from us at a faster speed of light. We will not get any information from that place. The name of this place is Hubble Sphere. Its radius is 14.4 billion light years. We can see anything from this distance now, because at one time the light from there reached our eyes. The light that is coming out now will not come.

If the universe continues to grow at such a rate, we will never see light from any other galaxy. The existence of any other galaxy will be lost forever. Then if a crazy scientist looking at the night sky claims that there are many more galaxies besides this Milky Way we might call him crazy. Now the question may be, is it possible that something has moved away from us forever in the last three hundred and eighty million years? Maybe a distant multiverse, a strange structure? We do not know. We can only look at the starry black sky of the night and wonder, what is on the other side of the horizon! (Theory of Relativity)
