yes, positrons were discovered in experiments in the 1930s just like theory had predicted. many other anti-particles have been discovered since.
Antimatter is a type of matter with an unusual quality - it has properties that are opposite to those of normal matter. For example, when antimatter comes into contact with normal matter, they annihilate each other, releasing a large amount of energy. Antimatter is rare in the universe and is usually produced in high-energy processes like particle accelerators.
Antihydrogen is a form of antimatter consisting of an antiproton and a positron (antielectron). When antihydrogen comes into contact with ordinary matter, they annihilate each other, releasing energy in the form of gamma rays. Scientists study antihydrogen to better understand the nature of antimatter and its interactions with ordinary matter.
Sometimes it is in opposition to antimatter. In this sense matter is everything that is composed of atoms, electrons, protons, neutrons and other more exotic particles. But not their anti particles. It also doesn't include various things such as energy or gravity (though both matter and antimatter may carry energy, and have gravitational fields)
This is beta decay, specifically beta plus decay. The beta particle that appears is the positron, which is the antimatter particle of the electron. Links can be found below for more information.
Matter is the basis for everything. Anything that exists has matter. Dark matter are anomalies that cannot account for "missing matter". Matter does not contain the solar energy and radio signals that travel through "empty space".
Yes!
its hypothetical, it shouldn't exist...
Yes, antimatter has been observed in laboratory experiments and high-energy particle collisions. The existence of antimatter is supported by the theoretical framework of quantum field theory, which predicts the existence of antimatter as a counterpart to ordinary matter. Additionally, antimatter has practical applications in medical imaging and research.
No, vampires dont exist and there is no proof and if there was it would be so cool
One has to go to far-away galaxies to get hold antimatter particles
There are no definite answers with our current level of understanding of antimatter at this point but scientists believe that this is the result of an imbalance in the production of matter and antimatter particles in the early universe. Another explanation for this phenomenon is that Antimatter may exist in relatively large amounts in far away galaxies due to inflation in the primordial time of the universe
There is no scientific proof that ghosts exist but there are thousands of photographs(not to mention audio or video!):)
people have proof that it use to exist but i doubt any one has that they have proof that they still live
No, but most believers don't need proof.
possibly, there is little proof that he does and no proof that he doesnt
No. There is no proof of the existence of mermaids because they do not exist.
No.
