The 4 Fundamental Forces (Interactions) Of Physics Explained: What Governs Our World?

Have you ever experimented gravity? For an example, when trying to ride a bike for the first time and falling again and again. Or have you ever played with magnets as a child?

I’m sure that the first time you saw those little metallic objects attracting each other you got really surprised. Usually, when children are totally driven crazy by an event or a natural effect they start to ask a lot of questions repeatedly in a funny way. They continuously say: “why?”

Although this might seem a childish approach to reality, it turns to be very deep when trying to investigate a phenomenon. As a matter of fact, physicists tend to use this method to build appropriate mathematical models that can describe how objects behave in different situations.

They need to build up laws that can predict the outcome of an experiment, and if they find an event that doesn’t match their theories, they start to correct their beginning principles.

And what do we have discovered thanks to this endless research? Where did this method brought us to? What governs our world? How can we resume all the existing sciences in just a handful of different types of forces? These puzzling questions are the topic of this video that will present you the four fundamental interactions that describe why our world is like the one we observe.
