Summary of Una nueva visión de la Relatividad General

00:00:00 - 00:10:00

This video provides a new perspective on the theory of relativity, illustrating how the curvature of space-time is caused by the mass of the Earth. It also shows how this curvature can be used to explain the movement of objects in the universe.

• 00:00:00 This video, titled "Una nueva visión de la Relatividad General", provides a new view of the relativity theory. It aims to show different representations of the theory, and propose a graphical interpretation that has not been established before. The idea behind this new representation is to take advantage of the video format's temporal dimension to faithfully reproduce what we learn in school up to high school, that free falls can be modeled by a force called gravity. This force allows us to predict the movement of objects, stating that they are attracted to each other and in particular to heavy objects like the Earth. However, this description is a mere approximation and fails when the attraction is too strong, as in the case of Mercury's orbit around the sun. Albert Einstein proposed a rigorous mathematical model in 1915 that allowed for more accurate descriptions of free falls. Einstein's theory does not rely on a distant force, but the space-time continuum itself that distortions and drags objects along with it. To understand this theory fully is important, and so to make it more accessible we make four major changes to the image of a tension-stretched elastic sheet: first, the objects appear to be located on the space-time surface as if they were suspended in a container of water
• 00:05:00 This video presents a new vision of relativity, in which space is curved rather than flat. It also illustrates the curvature of space-time by showing how it can be restored to its three dimensions. Finally, the main problem with this representation is that it ignores time, which is represented by a fourth dimension in the diagram. Space-time is considered to be a four-dimensional object with three dimensions of space and one dimension of time. However, time can also be doubled and curved, which is why it is necessary to find an artificial means of representing it. One idea is to add small clocks to the diagram at each point, turning it into a space-time-temporal diagram. This spatial-temporal diagram then becomes a tool for understanding how time flows differently in different places. However, this diagram still does not explain what causes objects to fall. To explain this, we need to eliminate one dimension of space in order to represent the temporal dimension. In fact, this dimension is what explains gravity. This new vision of relativity explains how lines drawn through time by humans appear to curve. This is because the curvature of space-time is caused by the mass of the Earth. This diagram in constant contraction represents what we call
• 00:10:00 This video presents a new perspective on the relativistic general theory of relativity by illustrating how the surface of a planet constantly accelerates upwards due to the natural movement of the square. If we launch an object with an initial velocity, however, it will continue in a straight line in the square as the square contracts, but as the square contracts the object is drawn towards the ground. This is how the moon orbits around Earth and Earth orbits around the sun.
