Hey cosmic enthusiasts! Buckle up because we're about to embark on a mind-bending journey into the cosmic mystery that's been keeping scientists up at night - dark matter!

Dark matter, a mysterious and elusive substance constituting about 27% of the universe, has intrigued scientists for decades. This invisible entity, which interacts solely through gravity, remains an enigma.

In this blog, we will delve into the complexities of dark matter, exploring its formation, recent advancements in research, detection methods, ongoing worldwide experiments, and the profound implications this cosmic puzzle holds for our understanding of the universe.

What is Dark Matter?

Dark matter is a hypothetical form of matter that does not emit, absorb, or reflect light, rendering it invisible to electromagnetic radiation. Its existence is deduced through gravitational effects on visible matter, such as galaxies and galaxy clusters. Despite its lack of interaction with electromagnetic forces, dark matter exerts gravitational influence, shaping the large-scale structure of the universe.

Formation of Dark Matter

The origins of dark matter are speculative and subject to ongoing research. The prevailing theories propose that dark matter particles emerged in the early stages of the universe during the Big Bang. These particles would have contributed to a primordial soup, evolving as the universe expanded and cooled, ultimately forming the cosmic web observed today.
