The Quest For The Elusive Dark Matter

Dark matter is a mysterious and unidentified form of matter that is thought to be composed of exotic, non-atomic particles that do not interact with light or any other form of electromagnetic radiation. 

Indeed, dark matter's very name refers to the fact that, because it does not dance readily with light, it is transparent and invisible to the entire electromagnetic spectrum. You can also check and protect your lens with a sturdy Oculus lens adapter through various online sources.

The Axion Dark Matter eXperiment (ADMX) has been at the forefront of the quest to find a WIMP alternative–the axion. 

The true nature and identity of dark matter are one of the greatest mysteries in modern astrophysics.

Why the quest matters

Early calculations indicated that the axion should sport a mass of approximately 5 microelectronic volts-which would make it about 100 billion times lighter than the electron. As a result, ADMX was designed to be most sensitive to very light masses within that range.

A particular set of circumstances–the axion's mass is most likely to fall into the much more hefty range of between approximately 50 to 1,500 microelectronic volts. 

This would mean that every cubic centimeter of the Universe would have to harbor on average ten million such extremely lightweight particles. 

Dark matter is not spread out evenly throughout the Universe, however, but forms clumps and branches of a weblike network called the Cosmic Web. 

Because of this, the local region of our Galaxy should contain approximately one trillion axions per cubic centimeter.
