In this video, I'll talk about the most mysterious topic of the universe's dark matter and dark energy and some related questions like why is dark matter Important and why dark energy is important. well, first we have to know what is dark matter and dark energy.

So Dark matter is like a form of matter thought to account for approximately 20 to 25% of the matter in the universe and about a quarter of its total energy density. Its presence is implied in a variety of astrophysical observations, including gravitational effects which cannot be explained by accepted theories of gravity unless more matter is present than can be seen. For this reason, most experts think that dark matter is abundant in the universe and that it has had a strong influence on its structure and evolution.

Dark matter is called dark. this is because it does not appear to interact with observable electromagnetic radiation, such as light, and so it is undetectable by existing astronomical instruments.

On the other hand, dark energy In physical cosmology and astronomy, dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe.

Dark energy is the most accepted hypothesis to explain the observations since the 1990s indicating that the universe is expanding at an accelerating rate.
