Annihilation of matter means that matter and anti-matter disappear into nothing. This conversely means that you get matter and anti-matter from nothing. When electron collide with positron you get two gamma rays. The simple question arise here that when you get nothing from matter and anti-matter, why you get those two gamma rays.

The answer is very simple. When the electron moves, it carries kinetic energy. When the positron moves, it carries kinetic energy. This kinetic energy is released in the form of two gamma rays. One from each particle. Logically one of the two gamma rays has to be anti-gamma ray. The gamma ray and anti-gamma ray should vanish into nothing.

(Now let us see the definition of annihilation given on Google.

I copy paste the same below.

"PHYSICS

the conversion of matter into energy, especially the mutual conversion of a particle and an antiparticle into electromagnetic radiation."

Now take the equation of Einstein. That is E = m c 2.

The speed of the light is very high. But let us take it as low as only one.

Then E = m *1*1.

You take the speed of light as one only. Then only you get one gamma ray from one electron.

That makes mass of one gamma ray or photon equal to the mass of electron or positron. The electron is a particle, whose mass can be measured. The mass of the photon can not be measured. As it is too less. It is supposed to be with out mass.

This is a great googly ball by Google. I am out.

The second question is why do two electrons do not annihilate to form two gamma rays. Why 'especially' particle and anti-particle only?

That is silly explanation by Google.)

The speed of the light is about 300,000,000 meters / second. C square comes to be 90,000,000,000,000,000. That means from one unit of mass you should get 90,000,000,000,000,000 units of energy.

Now you come to the annihilation of proton and anti-proton. You ultimately get electrons, positrons, gamma rays and neutrinos. These electrons and positrons can annihilate into nothing. The gamma rays, which includes anti-gamma rays vanish into nothing. Logically there has to be anti-neutrinos. Both neutrinos and anti-neutrinos vanish into nothing.

Same type of explanation can be given about annihilation of neutron and anti-neutron. They both vanish into nothing.

What is the end product of matter-antimatter annihilation?

The end product of matter-antimatter annihilation is energy in the form of photons (light particles) or other subatomic particles.


Where does dissipated energy go as in matter and anti-matter annihilation?

In matter-antimatter annihilation, the energy is primarily transformed into high-energy photons (gamma rays). These photons can then further interact and create new particles in a process called pair production or contribute to heating the surrounding environment. Ultimately, the energy from matter-antimatter annihilation is dispersed and can contribute to various physical processes.


What is an annihilation reaction?

Annihilation reaction is when you take matter and anti-matter and try to put them together and they cancel each other out. Try putting an electron and a positron together. What happens? They will cancel each other out.


Adding enough energy can cause matter to?

transform into energy through a process such as nuclear fusion or matter-antimatter annihilation.


How is antimatter stored and maintained to prevent annihilation upon contact with matter?

Antimatter is stored in specialized containers that use magnetic fields to keep it away from regular matter. This prevents annihilation, which occurs when antimatter comes into contact with matter, releasing a large amount of energy. The containers are kept in a vacuum to minimize the chance of contact with any particles. Additionally, the containers are cooled to very low temperatures to slow down the movement of the antimatter particles, reducing the likelihood of annihilation.

Can annihilation of matter occur between a positron and neutron?

No, a positron cannot react with a neutron in any kind of annihilation reaction. An electron and a positron can, and the same with a neutron and an anti-neutron, but it does not occur between a positron and a neutron.


Can annihilation take place in vaccuum?

yes, but you would obviously need some matter and some antimatter or there would be nothing toannihilate you do not need anything but these to components so it would be possible for an annihilation to happen in a vacuum

What was destroyed within the first seconds after the big bang?

Virtually all matter and anti-matter were annihilated shortly after the universe started expanding. Only a fraction of a percent of all matter survived that annihilation, and virtually no anti-matter.


What is the matter antimatter reaction called?

When matter and anti matter is combined, they are both annihilated, so it is called annihilation. This is why physicists are so confused - we don't know why there is matter left in this universe, if matter and anti matter were both created in equal quantities in the big bang.


What happens if antimatter touches matter?

When antimatter touches matter, they annihilate each other, releasing a large amount of energy in the form of gamma rays. This process is called annihilation.
