What Is Dark Matter?

  • Dark matter makes up for 80% of the universe around us.
  • Einstein believed that the empty space has the ability to store energy.
  • Two different types of dark matter are WIMPS and MACHOS.

The dark matter, the invisible, yet the most present matter that fills the space around us. Although many of the explanations around the dark matter are still theoretical, this deceptive mass influences everything, stars, planets, or even whole galaxies. 

Dark Matter Is (Still) Undetectable

The dark matter stays invisible to electromagnetic radiation, which renders it impossible to detect. At least when it comes to the measuring devices, we currently have. The thing about dark matter is that it does not seem to affect other matter in space like a black hole would do with not letting the light escape. It neither absorbs nor emits photons, hence the name ''dark'' matter. The scientists working in the fields of theoretical and experimental physics are estimating that the dark matter is making for a whopping 80% of the mass of the whole universe. It is all around, yet we still can not see it. 

Space Shaping Force

Even though it is invisible, dark matter plays an important role when it comes to the shape and form of our universe. Dark matter is something that provides gravity in the first place. Galaxies and other space objects we can see in space, their shape and movement, can not be explained when looking at the specific objects alone. Since galaxies and other different space formations tend to move away from each other, the dark matter is probably the responsible force for those space migrations. 

Einstein was the first scientist that postulated that all that vast emptiness around us is more than ‘’nothing’’. Nothing contains dark energy, which Einstein explained as a distinctive feature of space. From his perspective, there is a cosmological constant that the empty space has. It has the ability to contain energy, and it is that feature that enables the universe to expand. Einstein believed that, when it comes to the expansion of the universe, this dark energy would not be lost in the creation of new areas. The dark energy would not lose its potential as the universe would expand.  

WIMPS And MACHOS

So far, the scientists have speculated of two different dark matter types. The first category is called WIMPS, meaning Weakly Interacting Massive Particles. This type of dark matter explains how heavy particles we find in space could interact with ‘’normal’’ matter through a frail nuclear field. This theory suggests the overall abundance of dark matter in space. The other type is known as MACHOS, which stands for Massive Astrophysical Compact Halo Object. From this perspective, dark matter is viewed as a supermassive body that is like a star but simply does not glow enough. 

Whatever it is, it seems that dark matter and dark energy are still a mystery when it comes to collecting real and quantifiable data. Some theories have gone far and beyond when trying to work within Einstein’s theoretical framework, that they explain how dark energy found in space is very dynamic and that it acts as an inverse force of ‘’normal’’ matter.
