What does "Self-scattering" mean?

Table of Contents

Self-scattering refers to the way particles, like dark matter, interact with themselves. When dark matter particles collide or scatter off each other, it can influence how they group together and how structures in the universe, such as galaxies, form.

#Importance in the Universe

Self-scattering plays a key role in shaping the universe on a small scale. It helps to smooth out the distribution of dark matter, making it easier for normal matter to come together and form stars and galaxies. This interaction is essential for understanding the overall behavior of dark matter and its effects on cosmic structures.

#Connection to Dark Matter

Dark matter is a type of matter that does not emit light and is invisible, making it hard to detect directly. However, studying how it scatters can provide clues about its nature and properties. This understanding can lead to better models of how the universe evolves over time.
