## What is the explosive power of antimatter?

A gram of antimatter could produce an explosion the size of a nuclear bomb. However, humans have produced only a minuscule amount of antimatter. All of the antiprotons created at Fermilab’s Tevatron particle accelerator add up to only 15 nanograms. Those made at CERN amount to about 1 nanogram.

## How much energy is released when antimatter touches matter?

Using the convention that 1 kiloton TNT equivalent = 4.184×1012 joules (or one trillion calories of energy), one half gram of antimatter reacting with one half gram of ordinary matter (one gram total) results in 21.5 kilotons-equivalent of energy (the same as the atomic bomb dropped on Nagasaki in 1945).

What kind of energy does antimatter release?

When antimatter comes into contact with matter it annihilates: the mass of the particle and its antiparticle are converted into pure energy. Unfortunately, however, antimatter cannot be used as an energy source.

Does antimatter and matter explode?

“It’s true that when matter and antimatter meet, they do annihilate in a big explosion and convert their mass to energy.

### How much is antihydrogen worth?

Scientists claim that antimatter is the costliest material to make. In 1999, Nasa said it would cost \$62.5 trillion to produce a gram of antihydrogen. Seven years later, it was estimated that a gram of positrons (the antiparticle of the electron) would cost \$25bn to make.

### What happens if matter touches antimatter?

When matter and antimatter collide, the particles destroy each other, with a huge energy release. Depending on the colliding particles, not only is there a great energy release, but new, different particles may also be produced (such as neutrinos and various flavours of quark – see figure below).

What happens if matter and antimatter collide?

What happens if antimatter touches matter?

## Can antimatter be created out of energy?

As a result of the conservation of lepton and baryon numbers, antimatter (antiparticles) can be created out of energy, but only if a particle counterpart for every antiparticle is created as well. It will be demonstrated in the following sections.

## What are antimatter particles?

Antimatter particles share the same mass as their matter counterparts, but qualities such as electric charge are opposite. The positively charged positron, for example, is the antiparticle to the negatively charged electron.

Why is antimatter so scarce in the universe?

Both antimatter and matter were created after the big bang, and the universe should be made up of 50% matter, and 50% antimatter. But antimatter is incredibly scarce, and scientists still don’t know why. For a period of time after the Big Bang there was only energy.

What happens when matter and antimatter collide?

Since matter and antimatter carry an immense amount of energy (due to E = mc 2 ), their mutual annihilation is associated with production of intense photons ( gamma rays ), neutrinos, and sometimes less-massive particle–antiparticle pairs. One of best known processes is electron-positron annihilation.
