At the core of physics lies the aim to predict all kinds of phenomena and events by formulating different models.

Every measurement and formula is a manifestation of the four fundamental interactions. They can be regarded as the rules each and every particle in existence must abide, and without them, we would only have heaps of mass devoid of meaning everywhere.

• The strong interaction is responsible for binding the protons and neutrons in the atomic cores together.
• Humankind has harnessed this interaction for means to create nuclear energy.
• Humankind is attempting to further harness this interaction to invent a fusion reactor that would be a small-scale replica of the Sun.

• The electromagnetic interaction is responsible for binding the cores and the electron clouds in atoms together.
• This interaction is invoked in mirrors, cameras, x-ray imaging, microwave ovens, internet connections, and bluetooth and wifi technology, among many other contemporary tools.

• The weak interaction manifests as the ability of a particle to decay into other particles.
• These fall into three distinct types: α, β, and γ.
• This interaction was theorized as the three other interactions did not account for radioactive radiation, which has been found in experiments.

Besides the previous three, the physics community has interpreted gravitation to be an extension of this list of interactions. However, thanks to recent developments in the field of relativity, Einsteinian views of gravity have further established their foothold.

• Gravitation can be interpreted either as interaction between massive objects or as the ability of mass to curve the space surrounding it.
• Gravitation is responsible for the formation of any and all celestial objects, such as planets, stars, galaxies, and black holes.
