The four fundamental forces<br />
Having previously mentioned the four fundamental forms <strong>of</strong> matter, I will now describe the so-called four<br />
fundamental forces that are commonly discussed. These together are said to account for how we perceive<br />
and interact with our reality and how our Earth and space environments appear to us as they do. As I cover the<br />
following information, I would ask you to try to think in both really big and really small terms.<br />
A ‘force’ is any influence that attempts to change the motion or shape <strong>of</strong> something.<br />
The four fundamental forces that we are told exist are;<br />

The strong nuclear force<br />
The weak nuclear force<br />
The electromagnetic force<br />
The gravitational force<br />
The strong nuclear force. This binds protons to protons and neutrons to neutrons and protons to neutrons, to<br />
form the central nuclei <strong>of</strong> atoms. Protons would not normally want to be together because they both have the<br />
same charge (remember, like charges repel). Therefore, the strong nuclear force at that scale is what somehow<br />
overcomes that reluctance to be together and keeps all these particles bound in the form <strong>of</strong> an atom’s nucleus.<br />
It is also said to be the force that binds the internal structure <strong>of</strong> protons and neutrons to give these sub-atomic<br />
particles their own form. So, in this incredibly small-scale setting, the strong nuclear force is seen as an<br />
extremely short-range but exceptionally powerful force. It is the force responsible for the energy involved in<br />
atomic explosions!<br />
The weak nuclear force. This, as its name infers, is weaker than the strong nuclear force, but the job it does is<br />
also at the sub-atomic level. The weak force is responsible for a naturally occurring event that takes place when,<br />
for example, a neutron in the nucleus <strong>of</strong> an atom ‘changes itself’ (decays or reverts) into a single positive proton<br />
and a single negative electron. When this happens, some amount <strong>of</strong> energy that is no longer required is also<br />
given <strong>of</strong>f as radiation. In other words, the weak nuclear force is responsible for certain elements decaying from<br />
one element into another through either the conversion <strong>of</strong> neutrons into additional protons inside the nuclei <strong>of</strong><br />
their atoms, or the release from atoms <strong>of</strong> groups <strong>of</strong> particles consisting <strong>of</strong> protons and neutrons. An example <strong>of</strong><br />
decay would be if you had some uranium and left it for a very, very long time (hundreds <strong>of</strong> millions <strong>of</strong> years).<br />
You would eventually find that much <strong>of</strong> that uranium had turned into lead. In this sense, uranium is known as an<br />
‘unstable element’. This label is applied because certain elements release energy over time as radiation through<br />
this decay process to eventually become a different, and <strong>of</strong>ten ‘more stable’ element. Natural decay <strong>of</strong> elements<br />
is a quite common occurrence and it is generally not a dangerous thing for us humans, but it sometimes can be<br />
- it all depends on the actual element involved and the amount <strong>of</strong> energy released by its decay process.<br />
