<h1>Antimatter</h1>
|
|
|
|
<p>Every particle[ref] that we have met so far has a corresponding
|
|
anti-particle. These antiparticles have exactly the same mass[ref] as
|
|
the particle, but opposite charge[ref], and their lifetime and
|
|
stability are the same. When a particle, for example the electron,
|
|
meets its antiparticle, an anti-electron (or positron), they will
|
|
annihilate each other. This means that both particles disappear and
|
|
produce a huge amount of energy[ref]. This annihilation will only
|
|
occur when an antiparticle meets its matching partner. For example, an
|
|
antimuon will not annihilate with an electron. However, because there
|
|
is a lot more matter in our universe than antimatter, it is much more
|
|
likely for an antiparticle to find its partner very quickly and
|
|
annihilate. Hence, we do not see antiparticles very often in our
|
|
universe.</p>
