Dark Energy, in contrast to Dark Matter, makes up 69.5% of all matter and is responsible for the expansion of our universe. For reference, all other visible matter makes up 0.5% of the universe.The interesting component of Dark Energy is that it behaves oppositely to that of Gravity. In other words, it exerts a repulsive force instead of an attractive force. This is the main reason why we can say that the universe is expanding. Without Dark Energy, the universe wouldn’t have the capability to expand at all.

Dark Matter, although in considerably less abundance than Dark Energy, still makes up 30% of our universe.Dark Matter is an attractive force, similar to that of gravity, which holds matter together.Dark Matter plays a vital role in the formation of galaxies. This is primarily because of the fact that Dark Matter acts as an Invisible Glue that can hold galaxies together.

Dark Matter

Over time, various astronomers have studied supernovae and distant galaxies in order to observe the expansion of the universe. While researching, these scientists still had a set of expectations. One of these expectations was that the universe expanded at a constant rate.Much to their surprise, they noticed that the universe was expanding exponentially. This is very significant because up until now, scientists were under the assumption that the universe was not able to expanding this rapidly.Dark Energy serves as the reason why the universe is expanding exponentially and not linearly.

Research

To conclude:Dark Matter is an attractive force that holds matter together while Dark Energy is a repulsive force that pushes matter outwards.They both are very difficult to detect because they don’t emit, absorb, or reflect light at all. Despite this, they are still very widely researched. Scientists we able to uncover that the universe is expanding exponentially instead of linearly due to the abundance of Dark Energy.Overall, Dark Matter and Dark Energy are some of the most interesting occurrences in our universe, and we still have much to learn about them.

Conclusion

Dark Energy and Dark Matter are two of the most interesting components of our universe. Although they may sound the same, they have some key differences which separate them from each other. Today, I will be showing and explaining these very important distinctions, as well as explaining a similarity that they share.

What is Dark Energy and Dark Matter?

Despite the fact that both Dark Energy and Dark Matter are opposite in nature, there is one thing that is common between them: invisibility. Neither Dark Matter nor Dark Energy reflect, emit, or absorb ANY sort of light. This is the main reason why they both are incredibly difficult to detect.What this means is that they are both completely hidden, and the only way that we, as humans, know of their presence is through their effect on the Gravity.

Similarity

Dark Energy and Dark Matter are two of the most interesting phenomena in the universe. Today we will be exploring what they are and how they are fundamentally different from one another.

All the atoms and light in the universe together make up less than five percent of the total contents of the cosmos. The rest is composed of dark matter and dark energy, which are invisible but dominate the structure and evolution of the universe. Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales. Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe. What these substances are and how they work are some of the major challenges facing modern astronomers.
