![]() ![]() One method is to use the gravitational lensing of the background radiation from the dark matter to estimate the amount of dark matter present. There are several gravitational methods to detect and estimate the amount of dark matter in a system. For now, it is only through the gravitational effects the presence of dark matter can be predicted. If some forms of matter do not emit, scatter, or reflect light and other electromagnetic wave, those forms of matter are classified as dark matter. What telescopes see is the emitted, reflected or scattered light or other forms of electromagnetic waves. ![]() In cosmology and astronomy, dark matter means any form of matter that is not detectable through optical or radio telescopes. In this article, we are going to discuss what dark matter and antimatter are, their similarities, the definitions of dark matter and antimatter, and finally the difference between dark matter and antimatter. It is vital to have a very good understanding in these concepts in order to excel in such fields. Both of these concepts play very important roles in fields such as astronomy, astrophysics, particle physics, cosmology and even energy generation. Antimatter is a form of matter, which is the “negative”, or the “opposite” of matter. Dark matter is a form of matter, which is not observable through the electromagnetic spectrum but only observable through the gravitational interactions. Dark matter and antimatter are two forms of matter, which are least, understood.
