Antimatter consists of antiparticles, such as positrons and antiprotons, which can form antimatter atoms like antihydrogen. The theory of antimatter began in 1928 with Paul Dirac, and its existence was confirmed by Carl D. Anderson in 1932. Annihilation of matter and antimatter releases significant energy, but production is prohibitively expensive, costing around 100 quadrillion dollars for just one gram.

1. ANTI MATTER

5. What is antimatter?Matter contains particles (electrons, protons etc).Antimatter contains antiparticles (antielectrons, antiprotons etc).

7. An antielectron (also called "positron") and an antiproton could form an antihydrogen atom in the same way that an electron and a proton form a normal matter hydrogen atom.

9. HistoryThe modern theory of antimatter begins in 1928, with a paper by Paul Dirac. Dirac realized his version of the Schrödinger wave equation for electrons was predicting the possibility of antielectrons. These antielectrons were discovered by Carl D. Anderson in 1932 and named positrons.

10. Annihilation Annihilation is the process that occurs when a subatomic particle collides with its respective antiparticle.

11. Ex . Positron + electron = energy A Feynman diagram of a positron and an electron annihilating into a photon (gamma rays).

14. Big bang During big bang matter and antimatter was created in equal proportion.But due to unknown reasons matter overtook antimatter and what's left is mostly matter!This is called baryon asymmetry.This is one among the greatest unsolved problems in physics.

15. Storage Antimatter cannot be stored in a container made of ordinary matter because antimatter reacts with any matter it touches, annihilating itself and an equal amount of the container. Antimatter that is composed of charged particles can be contained by a combination of an electric field and a magnetic field in a device known as a Penning trap.

17. Uses Medical : Antimatter-matter reactions have practical applications in medical imaging, such as positron emission tomography (PET).

19. UsesFuel : The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy or the rough equivalent of 43 megatons of TNT !!!

21. Disadvantages Cost : To produce 1 gram of antimatter, CERN would need to spend 100 quadrillion dollars and run the antimatter factory for 100 billion years.

22. One researcher of the CERN laboratories, which produces antimatter regularly, said:“ If we could assemble all of the antimatter we've ever made at CERN and annihilate it with matter, we would have enough energy to light a single electric light bulb for a few minutes. “
