Does Dark Matter Have Energy – Today, scientists from the Dark Energy Survey published the results obtained over five years Researchers used the extensive catalog of dwarf galaxies around our Milky Way galaxy to investigate the nature of dark matter, the invisible form of matter that dominates the universe. These new measurements provide information about what can and cannot be done in dark matter
In particular, the new results constrain the minimum mass of dark matter particles, as well as the strength of the interaction between dark matter and normal matter.
Does Dark Matter Have Energy
According to this new result, a dark matter particle must be heavier than one zeptoelectronvolt, which is 10.

Electron-volt It is one trillionth of an electron mass The study also shows that the interaction of dark matter with normal matter should be about 1000 times weaker than the weak nuclear force. Of the known forces, only gravity is the weakest
This is illustrated by the results of two numerical simulations that predict the distribution of dark matter around a galaxy like our own Milky Way. The left panel indicates that dark matter particles move faster in the early universe (hot dark matter), while the right panel indicates that dark matter particles move slower (cooler dark matter). The hot dark matter model predicts that little dark matter surrounds our galaxy, and that this small amount of dark matter is inhabited by small satellite galaxies. By measuring the number of satellite galaxies, scientists can distinguish between these patterns of dark matter. Image: Bull and Baylen-Colchin (2017); Simulations by W. Robles, T. Kelly, and B.

The new measurements used data from the Dark Energy Study, a cosmological study of dark energy, the mysterious force that drives the universe’s accelerated expansion. In contrast, dark matter is gravitationally attracted, resisting the expansion of the universe and binding astronomical systems such as galaxies. The smallest “bride” galaxies may contain hundreds and thousands of times more dark matter than normal matter. Over the past five years, dark energy studies, combined with other studies, have doubled the known population of these small galaxies. Currently, their total number is more than 50
What Are Dark Matter And Dark Energy?
“The Dark Energy Survey’s analysis provides a new rigorous test of the standard cosmological paradigm and places strong constraints on many alternative models of dark matter,” said Dark Energy Survey spokesman Rich Krohn. “It’s a wonderful example of how large-scale cosmology can inform small-scale particle physics experiments.”
Dark matter makes up 85% of the matter in the universe, but we have yet to detect it directly in the laboratory. The gravitational effects of dark matter are indirect but evident in the motion of stars in galaxies, the dense distribution of galaxies in the Universe, and the abundance of light elements. Strong astrophysical evidence for the existence of dark matter has spurred many experimental searches on Earth, using instruments ranging from cryogenic detectors to powerful particle colliders buried deep in the Earth’s crust.
“Dark galaxies are some of the most valuable tools we have to study dark matter because they are sensitive to many of its fundamental properties at once,” said Ethan Nadler, lead author of the study and a graduate student at Stanford University and SLAC. . .
Can We See Dark Energy From Earth? New Experiments Offer Hope.
By combining the observed catalog of Milky Way galaxies with advanced cosmological models of the distribution of dark matter around the Milky Way, scientists were able to predict how the physical properties of dark matter would affect the number of small galaxies. Smaller galaxies form in regions where the density of dark matter in the early universe is slightly higher than average. Physical processes that flatten these high-density regions (if dark matter moves too fast or gain energy from interactions with normal matter) or prevent density fluctuations from forming galaxies (due to quantum interference effects) will reduce the number of observable galaxies. Survey on dark energy
“It’s amazing to see how the dark matter problem is being investigated from so many different experimental perspectives,” said Alex Drika-Wagner, a scientist at Fermilab and the University of Chicago, Dark Energy Research Fellow and one of the authors of the paper. “This is an important measurement for DES, and I really hope that future cosmological studies will help us understand what dark matter is.”
Dark energy research is a collaboration of more than 300 scientists from 25 institutions in six countries. For more information about the survey, visit the experiment’s website

We hope this guide will give you a good overview of the topic
In short, these features are needed to reconcile the geometry of space with the total observable matter in space—they explain the large-scale structure and observed expansion of the universe.
The Dark Side Of Cosmology: Dark Matter And Dark Energy
We have evidence of dark matter because we can see how it interacts gravitationally with visible matter and electromagnetic radiation. We know about dark energy from what we see in the accelerating expansion of the universe
To get a little more technical, observations of the cosmic microwave background (made by the Planck satellite and the Wilkenson Microwave Anisotropy Probe) show that the universe is geometric.
, or very close to it If the universe is geometrically flat, as observations and distributions suggest, complex densities of energy and matter.

But what is dark matter and dark energy? Dark matter is simply matter that neither emits nor absorbs electromagnetic radiation (light). And it is believed that the zero energy density of empty space is the main factor in the dark energy control process

A Coma Cluster of Galaxies In the 1930s, Fries Zucky studied a group of galaxies known as the “Coma Cluster of Galaxies”. He calculated mass, luminosity, distance
But he found that for such a movement to occur, it would need to be 400 times greater than the calculation He wondered why this discrepancy arose, so he did a lot of research
However, there is something driving this crowding that we cannot see And he called this unknown substance “dark matter”. He named it because it is something invisible to the human eye Dark matter is considered another hypothesis and was not widely accepted at the time Some other hypotheses about dark matter were also mentioned
