Astronomers in Germany have developed an artificial intelligence algorithm to help them map and explain the structure and dynamics of the universe around us up to a distance of 370 million light years with unprecedented precision
Astronomers in Germany have developed an artificial intelligence algorithm to help them map and explain the structure and dynamics of the universe around us with unprecedented precision. The team led by Francisco Kitaura from the Leibniz Institute for Astrophysics in Potsdam, reported findings in the journal Monthly Notices of the Royal Astronomical Society.
Scientists routinely use large telescopes to scan the sky, map the coordinates and estimate the distances to hundreds of thousands of galaxies, allowing them to create a large-scale map of the universe. However, the distribution that astronomers see is difficult to explain when the galaxies form complex cosmic networks containing clusters and fibers connecting them, and empty areas between them.
The driving force of this structure is gravity. These forces come mainly from two components, firstly the 5% of the visible universe that is made of 'normal' matter made up in the form of stars, planets, gas and dust that we can see and about 23% of invisible dark matter. Besides these, 72% of the universe is mainly made of mysterious 'dark energy', which manifests itself in gravitational push waves and is considered to be responsible for the accelerated expansion of the universe. Together, the three components are described in a model of the universe known as Lambda Cold Dark Matter (LCDM) which is the starting point for the Potsdam team's work.
Measurements of the residual heat of the Big Bang, or as it is more commonly known, the cosmic background radiation that was emitted 13.7 billion years ago, allow astronomers to determine the motion of the Local Group, the cluster of galaxies that includes the Milky Way. Astronomers tried to reconcile this movement with the predicted movement by the distribution of matter around us and therefore also with the help of gravitational forces, but were forced to compromise due to the difficulty in mapping the dark matter in that area.
"Finding the distribution of dark matter in relation to the catalog of galaxies is like building a geographical map of Europe from satellite images taken during the night that only show the lights coming from densely populated areas," said Dr. Kitaura.
To try to solve the problem he developed a new algorithm based on artificial intelligence. He started with fluctuations in the density of the universe seen in the cosmic background radiation map, and then they modeled the way matter crashed into galaxies as they are today 13 billion years after the Big Bang. The result was an algorithm that approximated the distribution and movement of the galaxies.
Dr. Kitaura comments: "Our exact calculations show that the direction of movement and 80% of the speed of the galaxies that make up the local group can be explained by the gravitational forces rising from the material up to a distance of 370 million light years from us. By comparison, the Andromeda Galaxy, the largest body in the Local Group is 2.5 million light-years away from us so we can measure the influence of distant galaxies on galaxies close to our home.
"Our results are also close to those predicted by the LCDM model. To explain the remaining 20% of the speed, we are required to consider the effect of matter at a distance of up to 460 million light years, but currently the data at these distances are less reliable.
"Despite these limitations, our model is a tremendous leap forward. With the help of artificial intelligence, we can model the universe around us with unprecedented precision and learn how the largest structures in the universe were formed."

The existing route is too long and winding for a train. In addition, there is a maximum angle at which a train can travel and therefore cannot use the section of the Sodom ramps adjacent to the existing road. In the other cases, it is adjacent to roads or sites that have already been damaged.

Sometimes with the universe is the laws of nature.
We won't always have to take distant telescopes and enter the bowels of the universe.
You can see legality in birth, life and end.
It can be understood that evolution is not only the animal growing.
The earth also has evolution and conditions that built it. And we have the laws of physics and atoms
And the butterfly effect also played a role, not to mention the big events.
Therefore, five billion years happened on the ball, every atom changed something that created a very special ball.
Despite the laws in nature and the universe, it is difficult to understand that there is another star that has passed through exactly such a path and absorbed an environment.
If we apply philosophy, we see that the legality of nature is reversed, is accidental, and has a finality.
that I think an inverted law I think about something we don't think about. Let's take Archimedes' law an equilateral triangle on a flat surface we have a law. Let's take the same law on a sphere, for example angles will be greater than 60 degrees. What does it mean that in XNUMXD the legality changes. If it changes in the sphere, let's look for an engineering structure in which the legality will change. All the time, the structure of DNA and genes changes over the years and creates evolution. Let's take the DNA structure and its shape similar to Bisley and see how the legality and power in such a field changes all the time.
From here he gave a scientific test.
First of all the structure of the star clusters visible in the picture. Like a picture of a human brain. Neuron and axon synapses and the second thing that needs to be checked is whether the structure of the universe is similar to Bisley.
Is it possible that the universe is expanding just like the human body is growing and the genes inside it are moving away from each other just like the stars are moving away from each other.
This means that the same space of the minus matter is the one that is enlarged. And when the space is enlarged, stars move away
Is it possible that the same space of the minus matter contains the same energies of the boson that we can hardly check the speed of their appearance and their size
These are all philosophical theories that science should try to test. And if it will help then for health.
All this is only because of a conclusion that the legality in nature is reversed, and the reason needs to be understood.
Greetings from friends Hillel Taub from all over
It means artificial intelligence. It is true that we are far from intelligent, but there are robots that have artificial intelligence that look quite natural. Watch the war robot bigdog, alphadog on YOUTUBE. It uses a trial and error algorithm called Q-LEARNING and its walking is very similar to that of a dog and its running to a horse. And regarding astronomy software, how can it contain elements of AI?.
Here are some examples
A. Pattern recognition = comparing a shape photographed in space to a reference shape in a database. Pattern recognition
B. Data mining = extracting elements from a database and identifying patterns in a place that looks like disorder.
data mining
third. Making a decision - after a comparison in identifying a pattern, which pattern is the most suitable, or what is the next step in assembling a picture puzzle, and more. Decision making
It is desirable to be precise that in the end, the neutrinos did not exceed the speed of light
Finished a good signature for everyone

Please do not mislead the readers, there is still no artificial intelligence.
There is a simulation of neural networks and different algorithms of different mathematical relatives.
There are also artificial evolution algorithms.
But if the researchers have indeed developed artificial intelligence, then this news is fundamentally important and overshadows even the previous groundbreaking news published here about netrins that are faster than the speed of light.
Correct a spelling mistake
Scientists routinely use large telescopes to scan the sky, map coordinates, and measure distances.
should be "appreciated"
A good signature for heretics

I'm just asking, actually 2.
1. Is it possible to conclude from this algorithm "where" the big bang was, that is, which way and in which direction did we move away from the starting point?
2. If 23% of the universe is dark matter and 72% is dark matter, how can you pretend and say that the universe is expanding forever? Isn't it more correct to say that we are missing most of the data - 95% of them to be precise.
A misleading title.
Today most models use all kinds of adaptive algorithms.
At all, there is no intelligence or reason in this. All in all number crunching.
I don't see where the royal intelligence comes in.
At what stage of the software?
Or is it simply the calculation method?
I really don't understand.
