yes, positrons were discovered in experiments in the 1930s just like theory had predicted. many other anti-particles have been discovered since.

Yes, antimatter has been experimentally observed through the creation and study of antiparticles such as the positron (antielectron) and antiproton. These antiparticles have properties opposite to their normal matter counterparts, providing evidence for the existence of antimatter.

What is matter with an unusual quality?

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.


What is anti hydrogen?

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.


What does it mean when you say matter in a scientific way?

In science, matter refers to anything that occupies space and has mass. It is made up of atoms and molecules that interact through physical and chemical processes. Matter can exist in various states such as solid, liquid, or gas.


What is a type of radioactive decay that involves emission from the nucleus of a high speed antimatter particle that is a counterpart of the electron?

Positron emission is a type of radioactive decay where a proton in the nucleus is converted into a neutron, resulting in the emission of a positron (antimatter equivalent of an electron) and a neutrino. This process helps to decrease the proton-neutron imbalance in the nucleus.


Matter does not contain?

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!


Why is antimatter so powerful?

its hypothetical, it shouldn't exist...


Is there any proof that antimatter exists?

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.

How can we get anti matteris there exist in a universe?

One has to go to far-away galaxies to get hold antimatter particles


Why is there not nearly as much antimatter than matter?

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

How much does one gram of antimatter?

Anti matter does NOT exist. As soon as it is in contact with matter which is anything ; solid , liquid , gas, they are both annihilated. You can think of antimatter as protons with a negative charge and electrons with as positive charge. So Proton^+ Proton^- = Annihilation (??? Energy) Electron ^- + electron^+(positron) = Annihilation (???? Energy).
