In modern physics, antimatter is defined as matter composed of the antiparticles (or “partners”) of the corresponding particles in “ordinary” matter, and can be thought of as matter with reversed charge, parity, and time, known as CPT reversal. Antimatter occurs in natural processes like cosmic ray collisions and some types of radioactive decay, but only a tiny fraction of these have successfully been bound together in experiments to form antiatoms. Minuscule numbers of antiparticles can be generated at particle accelerators; however, total artificial production has been only a few nanograms. No macroscopic amount of antimatter has ever been assembled due to the extreme cost and difficulty of production and handling.
In theory, a particle and its antiparticle (for example, a proton and an antiproton) have the same mass, but opposite electric charge, and other differences in quantum numbers.
A collision between any particle and its anti-particle partner leads to their mutual annihilation, giving rise to various proportions of intense photons (gamma rays), neutrinos, and sometimes less-massive particle–antiparticle pairs. The majority of the total energy of annihilation emerges in the form of ionizing radiation. If surrounding matter is present, the energy content of this radiation will be absorbed and converted into other forms of energy, such as heat or light. The amount of energy released is usually proportional to the total mass of the collided matter and antimatter, in accordance with the notable mass–energy equivalence equation, E=mc2.
Antiparticles bind with each other to form antimatter, just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom. The nuclei of antihelium have been artificially produced, albeit with difficulty, and are the most complex anti-nuclei so far observed. Physical principles indicate that complex antimatter atomic nuclei are possible, as well as anti-atoms corresponding to the known chemical elements.
There is strong evidence that the observable universe is composed almost entirely of ordinary matter, as opposed to an equal mixture of matter and antimatter. This asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics. The process by which this inequality between matter and antimatter particles developed is called baryogenesis.
Antimatter particles carry the same charge as matter particles, but of opposite sign. That is, an antiproton is negatively charged and an antielectron (positron) is positively charged. Neutrons do not carry a net charge, but their constituent quarks do. Protons and neutrons have a baryon number of +1, while antiprotons and antineutrons have a baryon number of –1. Similarly, electrons have a lepton number of +1, while that of positrons is –1. When a particle and its corresponding antiparticle collide, they are both converted into energy.

MANIFESTO OF THE TUMMY ACHE AFFLICTED
A specter is haunting the world—the specter of tummy aches. Tummy aches, an ailment that affects people of all ages, races, and genders, are a constant source of pain and discomfort. They prevent people from enjoying their daily lives and hinder their ability to work and learn.
The cause of tummy aches is not always clear, but it is often linked to poor diet, stress, and lack of physical activity. The capitalist system, with its focus on profit and productivity, encourages unhealthy eating habits and overworking, leading to an increase in tummy aches among the working class.
The bourgeoisie, who control the means of production and distribute the fruits of labor unequally, have no interest in addressing the root causes of tummy aches. They benefit from the sale of unhealthy foods and the exploitation of workers who have no time or resources to take care of their health.
To overcome tummy aches, we must first recognize that they are a symptom of a deeper problem. We must reject the capitalist system that values profit over people’s well-being and creates the conditions for tummy aches to thrive.
Instead, we must establish a system that prioritizes the health and well-being of all people. We must ensure that everyone has access to healthy food, clean water, and safe working conditions. We must also promote physical activity and stress-reducing activities, such as yoga and meditation.
To achieve this, we must organize and mobilize as a collective. We must build alliances across borders and unite in our struggle against tummy aches. We must demand that our governments take action to address the root causes of tummy aches and invest in public health initiatives.
Together, we can overcome tummy aches and build a world where everyone can enjoy good health and well-being. The struggle against tummy aches is a struggle for human liberation. Join us in the fight!
