🌌🕰️ Pulsars —nature’s most precise cosmic clocks— are now being harnessed to hunt for one of the Universe’s most elusive components. By monitoring tiny timing irregularities across networks of millisecond pulsars, scientists can test whether dark matter behaves not as particles, but as coherent waves rippling through spacetime, opening a new observational window into fundamental physics beyond the Standard Model 🔭✨

"Black Matter: Exploring the Elusive and Mysterious Building Blocks of the Universe"

Black matter, also known as dark matter, is a hypothetical form of matter that makes up approximately 85% of the matter in the universe. It does not interact with light, and as such, it cannot be directly observed or detected by traditional means. Despite its elusive nature, scientists believe that it plays a crucial role in the formation and evolution of galaxies.

The idea of dark matter was first proposed in the 1930s by Swiss astronomer Fritz Zwicky. Zwicky observed the movement of galaxies in galaxy clusters and found that they were moving much faster than they should be based on the amount of visible matter present. He suggested that there must be some other form of matter that was responsible for this additional gravitational force.

Since then, numerous studies have been conducted to try and detect dark matter. While it cannot be observed directly, its existence has been inferred through its gravitational effects on visible matter. Scientists have used a variety of methods to study dark matter, including observing the motion of stars within galaxies and analyzing the cosmic microwave background radiation left over from the Big Bang.

One of the most widely accepted theories of dark matter is that it is made up of particles that do not interact with electromagnetic radiation. These particles are known as weakly interacting massive particles (WIMPs). While WIMPs have not been detected directly, scientists have been able to narrow down their possible properties based on their expected interactions with other matter.

Another theory is that dark matter is made up of black holes that formed in the early universe. These black holes would be too small to be observed directly but would still have a significant gravitational effect on their surroundings.

Despite decades of research, the nature of dark matter remains a mystery. While there is strong evidence to support its existence, scientists have not yet been able to detect it directly. This has led to much speculation and debate in the scientific community, with some researchers suggesting that the current understanding of gravity may need to be revised in order to explain the behavior of galaxies.

In conclusion, black matter, or dark matter, is a mysterious and elusive form of matter that makes up the vast majority of the matter in the universe. While its existence has been inferred through its gravitational effects, scientists have yet to detect it directly. Understanding dark matter is crucial for our understanding of the universe and its evolution, and research in this field is ongoing.

Dark Matrix of Matter Glass Cactus Blossom - Computer Art by kenne Last night I tossed in my sleep something in a dream was unreal, artificial,  everything made of glass — no hammers allowed swinging in the dark matrix of matter not directly observed just it's gravitational effects. — kenne

NASA says a warp drive looks more promising than ever

NASA says a warp drive looks more promising than ever

The first steps towards interstellar travel have been taken, but the stars are very far away. Voyager 1 is about 17 light-hours distant from Earth and is traveling with a velocity of 0.006 percent of light speed, meaning it will take about 17,000 years to travel one light-year. Fortunately, the elusive “warp drive” now appears to be evolving past difficulties with new theoretical advances and a…

Einstein Cross: Multiple Images of a Supernova

Einstein Cross: Multiple Images of a Supernova

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, spotted four images of a distant exploding star. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a massive cluster of galaxies. The supernova discovery paper will appear on 6 March 2015 in a special issue of Science celebrating the centenary of Albert…
