Subatomic
Background Information
After the Big Bang, there were numerous subatomic particles created
from energy. Every particle had an anti-particle, a particle identical
to it but with an opposite spin. To begin, the basic indivisible
particle has been known as the quark, and its anti-particle, the
anti-quark. The quark has been classified in six categories, up,
down, charm, strange, top, bottom. They combine to form protons,
neutrons, lambdas, and other particles called baryons. Quarks can
also bind with anti-quarks (at a low temperature as so not to annihilate
each other) to form pions and kaons, which belong to the group
called meons. Another set of particles called leptons include particles
such as the electrons and muons, and heavier charged particles
called the tau and the neutrinos, which are almost mass-less and
difficult to detect.
In order for these formations to occur, four natural forces
including gravity, electromagnetic force, strong force, and weak
force are needed. Gravity is the weakest of the four forces.
However, what makes it unique is that gravity can act over great
distances, said to be infinite, allowing it to bind stars and
galaxies. The electromagnetic force helps to hold atoms together,
and like gravity, its range is infinite. The weak and strong
forces however have limited range. The weak force allows for
certain forms of radioactivity such as the nuclear reactions
of the sun. Lastly, the strong force, which is the strongest,
has the ability to combine quarks and anti-quarks together and
thus allowing them to form larger particles. In order to overall
explain the particles and forces that control them, scientists
have framed a theoretical Standard Model. This model incorporates
the quarks and leptons and their interactions through the strong,
weak, and electromagnetic forces. Physicists explain forces to
be transmitted between quarks and leptons by another category
of particles called gauge bosons and vastly differ from other
particles. The boson photon, which is a particle of light, carry
the electromagnetic force, gluons carry the strong force, charge
particles and neutral particles carry the weak force. It should
be noted that gravity is not noted in this model for the very
reason that there has been no bosons found that are responsible
for carrying gravity. However, physicists predict that there
is a theoretical particle called graviton, but there is no proof.
