According to a February 26, 2024 Phys.org article, researchers using pulsar measurements to study dark matter have found that the Milky Way galaxy is highly dynamic

Dark matter is a hypothetical form of matter that is not visible to conventional observation. It is believed to make up more than 80% of all matter in the cosmos. Dark matter is implied by gravitational effects that cannot be explained by general relativity. 

The EPTA collaboration has explored the possibility that pulsars can act as dark matter detectors. The researchers searched for ultralight dark matter, which is predicted to be distributed unevenly throughout the Milky Way. 

A pulsar is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation. The radiation can only be observed when a beam of emission is pointing toward Earth. The periods of pulsars make them useful tools for astronomers

Researchers using pulsarmeasurements to probe dark matter find Milky Way galaxy is highly dynamic. Dark matter comprises more than 80% of all matter in the cosmos but is invisible to conventional observation, because it seemingly does not interact with light or electromagnetic fields.

According to the February 26, 2024 Phys.org article, researchers using pulsar measurements to study dark matter have found that the Milky Way galaxy is highly dynamic. This finding suggests that dark matter may be more complex than previously thought, and could have implications for our understanding of the universe. 

Dark matter is a hypothetical type of matter that is thought to make up about 85% of the matter in the universe. It is invisible to light and other forms of electromagnetic radiation, but its presence can be inferred from its gravitational effects on visible matter. 

Pulsars are rapidly rotating neutron stars that emit beams of radiation. By studying the way that pulsars move, researchers can learn about the gravitational forces that are acting on them. In the recent study, researchers used pulsar measurements to map out the distribution of dark matter in the Milky Way galaxy. 

The researchers found that the dark matter distribution is not uniform, but rather is clumpy and filamentary. This suggests that the Milky Way galaxy is a highly dynamic system, with dark matter constantly moving and interacting. 

This finding is consistent with other recent studies that have suggested that dark matter may be more complex than previously thought. For example, some studies have suggested that dark matter may be made up of multiple types of particles, or that it may interact with itself in ways that are not yet understood. 

The new findings could have implications for our understanding of the universe. For example, they could help to explain why galaxies form and evolve in the way that they do. They could also help to shed light on the nature of dark matter itself. 

Overall, the new findings are a significant step forward in our understanding of dark matter. They suggest that dark matter is a complex and dynamic phenomenon, and that there is still much that we do not know about it.

Dark matter is a hypothetical form of matter that makes up more than 80% of the universe’s matter. It’s invisible and doesn’t interact with light or electromagnetic fields. Scientists can only infer its existence from its gravitational effects on visible matter

Dark matter is thought to give galaxies extra mass, which generates the extra gravity they need to stay intact. All galaxies are dominated by dark matter, and galaxies are thought to form inside immense halos of dark matter. 

Dark matter is difficult to detect in a laboratory because it doesn’t interact with ordinary baryonic matter and radiation except through gravity. It’s also about six times more abundant than ordinary visible matter

Dark matter is a substance that interacts with visible matter primarily through gravity. It’s called “dark matter” because it interacts with gravity like matter, but only through gravity

Dark matter is thought to add to the gravitation caused by visible matter. Astronomers know dark matter exists because visible matter doesn’t have enough gravitational force to hold galaxies together. Dark matter’s gravitational pull can bend light traveling from distant galaxies, causing their images to appear distorted when they reach our telescopes. 

Dark matter is thought to give galaxies extra mass, which generates the extra gravity they need to stay intact. Galaxies rotate so quickly that the gravity generated by their observable matter alone couldn’t possibly hold them together

We call it “dark” because we can’t see it. Unlike visible matter (matter we can see, including stars, planets, water, etc.), it doesn’t appear to release or absorb light, or interact with other matter except through gravity
