The map, based on data collected over 15 years from a telescope in the Atacama Desert in Chile, shows the distribution of dark matter in the southern sky region, and is the most accurate and detailed map of its kind ever created
Dark matter is a mysterious substance that makes up about 85% of the matter in the universe, but it does not interact with light, so it cannot be seen directly. Instead, scientists have to infer the existence of dark matter from its gravitational effects on visible matter, such as stars and galaxies.
The new map of dark matter was created through gravitational bending, a phenomenon that occurs when the gravity of a massive object, such as a galaxy or galaxy cluster, bends and distorts light from more distant objects. By analyzing how light is bent and distorted by the dark matter in the southern sky, the researchers were able to create a detailed map of the distribution of dark matter in the region.
The map is significant because it provides strong evidence that Einstein's theory of general relativity is correct. According to general relativity, the distribution of matter in the universe should determine the way space is curved, which in turn affects the way light travels through the universe. The new map of dark matter confirms that the curvature of space in the southern sky is consistent with the predictions of general relativity.
The map also has important implications for our understanding of the structure of the universe and its evolution. Dark matter is thought to play a key role in the formation of large-scale structures, such as galaxies and galaxy clusters, and the new map provides a detailed picture of the distribution of dark matter in the southern sky that can be used to test and refine theories about how these structures form.
Dr. Alex Darlicka-Wagner, a scientist at the Fermi National Accelerator Laboratory of the US Department of Energy and one of the authors of the study:
"This new map is a testament to the increased sensitivity of the dark energy camera and the hard work of the great collaboration of scientists from around the world who made this analysis possible. We are particularly excited because this analysis shows the full potential of the dark energy survey for studying the nature of dark matter."
The findings were made using the ACT scientific instrument, which operated for 15 years in Chile's Atacama Desert and was decommissioned in September 2022. However, additional papers presenting results from the final series of observations are expected to be submitted soon, and the Simmons Observatory will conduct future observations at the same site when a new telescope is expected to begin operating. in 2024. This new instrument will be able to map the sky almost 10 times faster than ACT.

Aber's hypothesis regarding the concept of dark matter.
In the neural universe the infinite space is full of passive time, which is absolute rest and absolute cold. The infinite space is also full of energy.
Since passive time and energy are ethereal concepts, cosmologists believed that infinite space was empty.
But the infinite space is filled with two "continuous quantitative things" which are passive time and energy.
The passive time is an absolute resting medium that transmits the sunlight, with the help of waves of passive time.
The infinite space is the place where stars are formed, according to the concept that by combining amounts of passive time and energy, physical forms such as gold, carbon, hydrogen, etc.
Hence the belief of invisible dark matter.
This belief rests on the Newtonian belief that matter is a quantitative concept
which fulfills the rule "a lot of matter a lot of gravity"
But matter is not a quantitative concept, and is a physical form.
If a geometric form is perceived by combining quantities of a closed line, and within it a quantity of space, then a physical form is perceived by combining quantities of passive time and energy.
It is the neural infinite space that creates the material of the stars, and when a star ceases to exist, it disintegrates into passive time and energy, and these are dispersed in the infinite space.
The universe is wonderful, but geometry has cracked this secret, according to a similarity between a physical shape and a geometric shape.

The big bang theory makes no sense.
If there was a big bang and all the material would be thrown at once in a fraction of a second explosion.
About 14 billion years ago, when all the matter in the visible universe was arranged around the perimeter of the universe like a hollow balloon with an empty center.
But matter is more or less evenly distributed throughout the universe so this shows two things.
a) That the material continues to be created all the time and fills the space.
b) that somewhere beyond our observation range outside the observable universe there are huge black holes that attract the galaxies and cause them to accelerate and move away
There is a lot of nonsense here. Current physics succeeds in explaining most of cosmology, in a surprising way.
So dark matter is not understood, and there is an alternative theory. It still uses general relations only with a cosmological constant.
What do you even see in this picture? Absolute gibberish
It's amazing what knowledge Einstein had.
It is a gift from God.
I don't understand it. But the article implies that they used the theory of relativity to calculate the disappearances. So it is strange that the conclusion from this is that the theory is true. Because the calculations will probably match..
What did I miss?
It means that the growth rate of the universe corresponds to a. A combination of the theory of relativity b. and the presence of dark matter.
Indeed the debate of dark matter or modified gravitation theory remains open. In my opinion, there is no proof in the article that dark matter exists, but there is an illustration in it that in order for the outdated equations of relativity to work, they require dark matter.
It is possible otherwise. There is an update to the theory of relativity with a serious theoretical basis from a Spinoza prize winner. There were criticisms of the theory and the researcher answered them in a second article.
I am in favor of the theory of gravitational entropy by Verlind Erik, but this is my personal opinion. Without the assumptions of gravity behaving as if it were dark matter, suitable for calculating force arising from entropy of particles and anti de Sitter quantum entangled space where the space itself is entangled even in the absence of matter at all but dark matter is not needed. Physics takes time to update perceptions.
As such the article described here does not make sense on the contrary. Published in The Astrophysical Journal Letters.

Dark matter is a force, or rather a force of repulsion, it is the material invisible to the devices known now that repels the matter from meeting with other matter and disperses the matter in the universe exactly opposite to the force of attraction that binds matter to matter and thus in fact stars and planets and asteroids, meteors, and all galaxies are created. Matter has an attraction to dark matter. An invisible force of repulsion and therefore the universe expands but in groups (galaxies) and perhaps also in groups of universes but the great mystery is not all this a matrix controlled by the hands of the creator or creators
Sorry for the ignorance, but to perform an experiment using tools that work on the basis of gravitational theory and come to the conclusion that the gravitational theory is correct is not a tautology.
exciting
Sorry for the ignorance, but using the theory of gravitational curvature in observations (which is a product of the theory of relativity) and then creating a map and claiming that it attacks the theory of relativity is not a tautology and a research error?
Does not verify but contradicts the lie of relativity.
The mere assertion of the existence of dark matter or dark energy, and not measuring them experimentally, completely contradicts the theory of relativity.
It is important to note that this is not a measurement map, but a calculation from the dynamics of galaxies how much mass/energy needs to be added to them so that the Einstein equation fits the astronomical observations.
Not surprisingly at all, here too we see that the universe is neither isotropic nor homogeneous, but I am sure that no one will be in a hurry to throw away the cosmological principle.
In relation to gravitational repulsion, even if the phenomenon occurs due to gravitational phenomena, this does not mean that Einstein's theory of gravity is correct. This is given that it is indeed a gravitational effect in general and not an optical contamination from refraction of light in particle dust, an optical distortion of the measuring device or an incorrect analysis of the data.
Reminds what happens with redshift that there are several effects such as Accept Compton, gravitational effects, effects of energy loss as the interaction of light and matter, and more that can explain the phenomenon, and modern astrophysics relies on the Doppler effect even though Hubble himself was not at all sure of the exact source and the purity of the conclusion that the scientific consensus went towards
The use of the pair of words (dark matter) is based on a naive Newtonian idea, that the actual matter that can be held in the hands - has gravity.
And the scientists say - if real matter has gravity, then dark matter also has gravity.
The word substance is related to Newton who stated -
Material is a quantitative thing, and a lot of material has a lot of gravity.
But Newton was wrong, and matter is not a quantitative concept, and has no gravity.
There are only 5 continuous quantitative things in the world, and they are length, area, volume,
Passive time and energy.
Passive time and energy are two ethereal quantitative things, and a combination
Amounts of passive time and energy - the tangible material familiar to us is created.
Infinite space is full of passive time and full of energy.
This concept creates a new physics, completely different from the physics of Newton and Einstein.
This physics appears in the book "Esbar's Magical Journey on the Wings of Natural Knowledge"
