No, you actually don't get any energy out of this process. The nature of antimatter is somewhat better understood than the nature of dark matter.Could dark energy be coming from the constant creation and annihilation of matter-anti matter pairs that form spontaneously in the vacuum of deep space?.Antimatter annihilates when collided with normal matter but dark matter does not display such behavior.Dark matter does not interact with the electromagnetic spectrum therefore, it is not detectable with any electromagnetic wave detecting method (ex: telescopes, radio receivers, etc.). Antimatter can be detected via the electromagnetic spectrum.What is the difference between Dark Matter and Antimatter? For an example, an antihydrogen atom can be formed by the combination of an antiproton and an antielectron (also known as the positron). Antimatter is the matter made up of antiparticles. For the annihilation to occur, both the particle and the antiparticle must be in the appropriate quantum states. If a particle and an antiparticle contacts, they will annihilate to produce energy. However, charge is not the only difference between particles and antiparticles. Antiparticle is a particle having exactly same mass but the opposite charge. Most of the particles we know have antiparticles. To understand antimatter one must first understand what antiparticles are. The amount of dark matter in the universe plays a major role in deciding the expansion rate and thereby the future of the universe. According to the observations based on large structures of the observable universe based on Friedmann equations and the FLRW metric, it has been estimated that dark matter accounts for about 23 percent of the total mass – energy density of the observable universe whereas ordinary matter only contributes approximately 4.6 percent for the mass – energy density of the observable universe. For galaxies and galaxy clusters, galactic rotations, attractions, and collisions can be used to determine the amount of dark matter present. 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.
