What is the theory of antimatter?

Antimatter is a material composed of so-called antiparticles. It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. When a particle and its antiparticle meet, they annihilate each other – disappearing in a burst of light.

What is the ratio of matter to antimatter in the universe?

A curious number that appeared in the above discussion was the few parts in 109 asymmetry initially between matter and antimatter (or equivalently, the ratio 10−9 of protons to photons in the present universe).

How does antimatter react with matter?

Mixing antimatter and matter usually has predictably violent consequences – the two annihilate one another in a fierce burst of energy. Charged antimatter particles share the same mass as their normal-matter counterparts but bear the opposite charge. …

Is antimatter the opposite of matter?

Antimatter is the opposite of normal matter. More specifically, the sub-atomic particles of antimatter have properties opposite those of normal matter. From a simple perspective, however, atoms have particles that are known as electrons, protons and neutrons inside of them.

How can we make antimatter?

To create anti-matter, you need to transfer energy into mass. This is done by compressing a lot of energy into a very small space. When energy transforms into mass, both matter and antimatter are created in equal amounts.

Why does antimatter exist?

Antimatter may exist in relatively large amounts in far-away galaxies due to cosmic inflation in the primordial time of the universe.

What is the definition of antimatter?

Antimatter. In particle physics, antimatter is the extension of the concept of the antiparticle to matter, where antimatter is composed of antiparticles in the same way that normal matter is composed of particles. For example, an antielectron (a positron, an electron with a positive charge) and an antiproton (a proton with a negative charge)…

What is antimatter universe?

Antimatter is the opposite of normal matter. More specifically, the sub-atomic particles of antimatter have properties opposite those of normal matter. The electrical charge of those particles is reversed. Antimatter was created along with matter after the Big Bang, but antimatter is rare in today’s universe, and scientists aren’t sure why.
