How fast is the growing speed of the Universe?

The shape of the universe.

What is the shape of the universe? (1) This is a very good question because that speed can explain, why we cannot see the location of the big bang. In somewhere past the cosmologists got a fascinating idea that galaxies would be in the layer of the ball, what is called as the universe, and then by searching the directions of the galaxies, the researchers could define the point, where the big bang happened, and then the telescopes would be turned to the "south pole" of the galaxy.

One of the things is that I'm talking here the direction of the galaxy, what is to the direction of the point, where the big bang happened as the "south pole", and in fact, the black holes might have polar like planets and stars. The idea was simply the position of the galaxy is telling, where the big bang was, and then the telescopes would easily find that point.

And then the astronomers were looking at the stars more and more effective telescopes, and they noticed that there were many galaxies in location, what supposed to be in the direction of the big bang. But as you see the scientists must sometimes adjust their theories, because observations are chancing our knowledge.

The idea of a two-dimensional ball-layer changed to the combination of the multiple models, and the thing, what kind of model of the universe is used depends on the scale. as you might know, the Universe is very big, and if we would look at things by using the very large scale model, we would think that the universe is the straight layer, and that model could be suitable in the local galaxy group.

But then the thing, what is called "U-shaped" or saddle from would turn to dominate, if the scale is smaller, and the observed area, of the universe, is getting bigger. Then the universe is turning to the ball, if the area, what observer sees is big enough. And here I must say, that the observer is always hypothetical. I have thought the universe as the 3D ball-layer, where the galaxies are in the different locations and positions, and the width of this layer is extremely large.

Why the expansion speed of the Universe is slower than it should (2)

By using the most modern telescopes, we can see the distances of billions of light-years. That means that we can see objects from that distance. The distance of a farthest known galaxy is 13 billion light-years and the size of the universe is 46 billion light-years. So we see things, what is happening in the 13 billion years ago.

But when we are thinking that we cannot see the big bang, there is one very interesting theory, and that thing is that the beginning of the existence of the expanding speed of the universe was near the speed of light. And then it started to slow. There should be something, that slows that speed, and that would mean that there is a massive black hole in the place, where the big bang has happened.

The real number of expanding the speed of expanding the universe is about 67 meters per second, and that means that there is something, that would break the expansion speed. That thing could be the mutual gravity of the galaxies, the dark material, and the last hypothesis is that in the center of the universe is the giant black hole, what is larger than any galaxy, and that thing would pull the galaxies to it. This thing makes science very nice before we can create and confirm the models of everything, we must realize, that everything is possible in the world, where black holes are dominating their environment, and massive eruptions are disturbing the harmony.

Even Einstein was human

Even Einstein was human

The problem with Albert Einstein is that he and his ideas are so fantastic and the same time so massive, that we cannot question them. So when we are thinking about Einstein's theories, what was fundamental in his lifetime, or when he introduced them to the world, we must remember two things. 

Einstein didn't have supercomputers, and when he introduced the Theory of Special Relativity in 1905 and Theory of Common Relativity in 1915, those theories became two of the most awesome and well-known formulas. But we don't know why Einstein created those formulas? Who ordered that man make those theories, and what was hypothesis when that job was given to Einstein? 

So there is another thing, what we are many times forget to ask, and that thing is "what were the values, what Einstein used? Did he use the theoretical speed of light, what is 300 000 m/s or did he used the value, what was metered by Michelson, and what is approximately 299 792 458 m/s? The thing is that there are differences with those numbers. And when we are thinking about the time, what Einstein used for creating those formulas, he made excellent work. But he 'forgot that the space is never straight. 

When we are calculating things by using extremely long decimal numbers, we can say that Einstein's formulas are not matching with reality. That means that those famous formulas are working in the common and enough large scale, but when we are going to the very small areas there are mistakes. So Einstein's theories work with entirety, but unique details are problems. This is the problem with physics and every other formula in the world. 

Those formulas are made in the time, there were no supercomputers and float number algorithms, which can handle extremely long decimal numbers, which gives enough accuracy for calculations. Sometimes people have asked, what if the value for the speed of light, what was reported by Michelson was wrong? In that case, every single laser ranger in the world would show the wrong numbers. 

This would open the route for very interesting philosophical discussions about things, what might be wrong, but commonly thought to be right. And if we would someday meter the different value for the speed of light, what would we do? Would we replace the speed of light and other meterings, where were used the laser meter again?
