Introduction
An introduction is typically the first section of a piece of writing, and its purpose is to introduce the topic or main idea of the text.
In an academic or scientific context, an introduction often includes a literature review,
which is a summary of previous research on the topic.
The introduction should provide enough background information to help the reader understand the context and significance of the topic,
and it should also clearly state the main purpose or research question that the text aims to address.
A strong introduction should be engaging and clearly outline the key points that will be covered in the rest of the text
What is dark matter?
Dark matter is a form of matter that scientists believe makes up approximately 85% of the mass of the universe.
It is called "dark" because it does not interact with light or other forms of electromagnetic radiation,
which means it is invisible to telescopes and other instruments that detect electromagnetic radiation.
Despite its name, dark matter is not actually "dark" in the sense of being completely devoid of light or energy.
Rather, it is called "dark" because it does not emit, absorb, or reflect light, making it difficult to detect.
Scientists believe that dark matter plays a crucial role in the evolution and structure of the universe.
For example, it is thought to be responsible for the gravitational force that holds galaxies and galaxy clusters together,
as well as the formation of large-scale structures in the universe such as galaxy clusters and cosmic filaments.
Despite the important role that dark matter is thought to play in the universe, its true nature is still a mystery.
Scientists are working to better understand the properties of dark matter and how it interacts with other forms of matter and energy.
There are several theoretical models that attempt to explain the nature of dark matter, but much is still unknown and more research is needed to fully understand this mysterious component of the universe.
What is dark energy?
Dark energy is a mysterious force that is thought to be responsible for the observed acceleration of the expansion of the universe.
It is thought to make up about 68% of the total energy in the universe.
Dark energy is called "dark" because it does not interact with light or other forms of electromagnetic radiation,
which means it is invisible to telescopes and other instruments that detect electromagnetic radiation.
Despite its name, dark energy is not actually "dark" in the sense of being completely devoid of light or energy.
Rather, it is called "dark" because it does not emit, absorb, or reflect light, making it difficult to detect.
The concept of dark energy was first proposed to explain the observed acceleration of the expansion of the universe,
which was discovered in the late 1990s through the study of supernovae. This acceleration cannot be explained by the known laws of physics, which led scientists to propose the existence of a new, unknown force that could be causing the expansion to accelerate.
There are several theoretical models that attempt to explain the nature of dark energy, but much is still unknown and more research is needed to fully understand this mysterious force. Scientists are working to develop new theories and test existing ones in order to better understand the properties and behavior of dark energy, and how it affects the evolution of the universe.
Current theories and outstanding questions:
There are several theoretical models that attempt to explain the nature of dark matter and dark energy, but much is still unknown.
Scientists are working to better understand these mysterious components of the universe and how they affect the evolution of the cosmos.
I hope this outline gives you a good overview of the nature of dark matter and dark energy!
