Cultural information on key basic concepts to understand Albert Einstein's Theory of Relativity.
Description of the content:

We explain how speed, translated into movement, explains time dilation through special relativity. How gravity, translated into curvature of the spacetime fabric, explains the movement of bodies and particles in the universe, according to general relativity. And how everything, as a whole, gives way to the ambiguity of time as we perceive it through our senses.

We will review some basic equations that give meaning to our questioning and that help us understand the mind of this great Swiss, German and American scientist. Questions that this content resolves: What is mass? What is inertia? What does the movement mean? What is the equivalence principle? E = mc2? (mc^2) What is time? Is there time? What is gravity? Gravity is not a force!

Special Theory of Relativity (1905): Time is relative. It varies according to the speed at which a body moves through space. Our time does not exist. Everything is a product of our great imagination.

Theory of general relativity (19151916): it is impossible to distinguish an accelerated movement from a body that is subjected to the action of gravity. Mass tells space how to curve, and space tells mass how to move.

The universe is the way it is, and we can't do anything to change it. We are condemned to abide by its laws. Therefore, what prevents us from traveling at the speed of light is not relativity, nor any other theory imposed by another human being, but the universe itself. It is our species, who, through experiments and observations, has collected data in order to understand the universe. And to understand it, we make theories that make sense of that data. Theories, in turn, motivate us to look for more data to show that they are true. But not the other way around. We cannot create data to make sense of our theories, it would not make sense.

If we take this to an example from everyday life, we can imagine that when a person hears something fall while in a different room from the event, a possible theory would be, for example, that the culprit was his pet. His information would be the noise he heard, but until he saw the security cameras, or immediately went to look, he could not verify that the animal had indeed been responsible for the event. Let's appreciate every second of our existence.
