This video discusses the basics of dreaming and how to interpret them. Dreams can be different for different people, but they often have important clues for resolving problems or addressing anxieties.

• 00:00:00 In this video, Pedro Ferreira, a professor at Oxford University, discusses the theory of relativity with Punset. Ferreira discusses some astronomical phenomena that are related to relativity, and also talks about the pieces of the theory that remain unsolved. In his segment, Elsa Punset discusses another aspect of relativity that is still mysterious, the role of the unconscious. Ferreira discusses how relativity has changed our understanding of the universe over the last few decades, and how it has helped us predict and confirm the existence of a uniform, expanding space-time. We see in this video how relativity has allowed us to understand the universe on a much larger scale, and how its complex structure is the result of collisions between objects.
• 00:05:00 The theory of relativity is explained in a fun and easy way in this video, with examples such as planets causing a change in space-time, which form changes, and there is no way to explain what happens without understanding what Einstein said in a certain way. Even though I think we should be fair to Newton's law of gravity, which remains immensely useful to explain many things, for example, explains almost everything that happens on Earth, Einstein's theory of relativity also allows us to describe quite well the movement and rotation of galaxies with Newton's law of gravity. Lenny el estudioso, in his book The State of the Universe, states that the space-time fabric curves around deep and desolate abysses, and that the movement and collision of objects creates waves in this space-time. These are called gravitational waves. Although scientists have evidence that these waves exist, they have not yet been able to detect one exactly like water waves in a pond. Gravitational waves lose strength as they get further away from their originating location. When observed on Earth, they are very weak and require very precise experiments to be detected. In your book The State of the Universe, you state that one of the most fascinating aspects of Einstein's theory of relativity is the conceptual
• 00:10:00 In this video, physicist and educator, Dr. Eduardo Bañados, discusses the theory of general relativity, which states that the universe is constantly moving and undergoing gravitational waves. Bañados points out that although these waves are difficult to observe, they are very energetic and propagate outward, much like an explosion in space-time. He believes that one of the key challenges of modern physics is to measure these waves. If this were to be accomplished, it would be a clear demonstration of the theory of relativity.
• 00:15:00 In the video, E.D.Dington discusses the theory of relativity. He argues that at the time it was completely bizarre, Einstein had to learn a new form of mathematics, learn it himself, and formulate a new theory in a way that no one understood. However, now that we understand it, although some people are scared of it, it still exists. Those who do not know the theory of relativity have fear of learning math, but I teach it at Oxford and I believe my students enjoy relativity theory. Despite its initial seeming implausibility, the theory of relativity has been proven to be true over the last 100 years, and has led to the discovery of other phenomena that arise from it. For example, it is now understood that the speed of light is constant, and that the theory of relativity is a general theory of relativity. It has allowed us to understand the universe in a more complex and changing way, and has led to the development of more ambitious and sophisticated experiments, such as the collider at CERN. Freud's contributions to our understanding of the unconscious were significant, but his view of the psyche was skewed by his conviction that there had to be a suppression of negative emotions in order to achieve a healthy psyche. This view had a significant
• 00:20:00 The video discusses the theory of relativity, which is summarized as follows: Emotion can be suppressed, but the unconscious still dictates our behavior silently, like a sheet of paper that has been folded over for a long time. We can keep it smooth with our hand, but as soon as we release it, it folds back up. Now, we're going to suggest a little journey. The unconscious, like if we were exiting the universe and looking for answers in some of the black holes that form it, and one saying that a dream without interpretation is like a letter without a postal address, is your unconscious with a message for you. My dream starts in a walled area, and I was there with a friend on the wall. There were gaps, but they were blocked by bars we could not cross. Then, I tell my friend not to worry, and we run and jump over the bars. We then fly over women in burkas, and finally land. I wake up with a feeling of joy, and it was very beautiful. Very beautiful. In that dream, I feel like I'm trying to find a solution. If in the figure of that female friend who appears and tells me not to wait, I say no,
• 00:25:00 In this video, José Luis explains the basics of dreaming, including the importance of being aware when you're dreaming and the importance of symbols. He also talks about how dreams can be different for different people and how to contextualize your dream in the moment of your life. Finally, he mentions that dreams can have important clues for resolving problems or addressing anxieties.
