IN BRIEF Dark energy: makes up about 68% of the Universe. Accelerates the expansion of the Universe due to its repulsive nature. Dark matter and dark energy: two great mysteries of astrophysics. Recent progress shows that the expansion of the Universe is faster than expected. Use of telescopes like Hubble and Euclid to study these … Read more
IN BRIEF Dark matter makes up about 85% of the mass of the Universe. It is invisible and undetectable, making its study complex. Represents one of the biggest mysteries of modern cosmology. Its existence is necessary to explain the movement of galaxies. Theories like modified gravity attempt to unravel this mystery. Less than 5% of … Read more
IN BRIEF Big Bang: Cosmological model on the origin of the Universe. Describes the evolution of the Universe from a dense and homogeneous state. Observational evidence, such as the cosmic microwave background. Explained by the abundance of primordial helium. Diverse data sources corroborate the theory. Scientific consensus on the birth of the Universe from the … Read more
IN BRIEF Modern Astronomy: study of celestial objects and their properties. Galileo: pioneer who laid the foundations of modern science. Universal Gravitation: discovery integrating different physical approaches. Atomic Physics: fundamental for understanding the Universe.

IN SHORT Quantum physics and cosmology emerged in the early 20th century. Quantum cosmology describes the early moments of the Universe. The concept of quantum multiverse suggests an infinity of universes. Quantum gravity raises many questions about the nature of the Universe. Big Bang and particle physics: essential links. Projects on loop quantum cosmology are … Read more
IN BRIEF String theory: fundamental theoretical framework in physics. The fundamental objects are vibrating strings. Elementary particles correspond to the different vibrations of the strings. Famous for its ambition to be the “theory of everything”, unifying the forces of nature. Involves 11 dimensions in certain formulations. A necessary popularization to make science accessible. Exploration of … Read more
IN BRIEF Hidden dimensions in the Universe: concepts and theories. Mechanism to confer mass to neutrinos. Physics of particles confined on surfaces called branes. Exploration of hidden variables in quantum physics. Kaluza-Klein theory and additional dimensions. Search for particles of the standard model and the graviton. Links with concepts of multiverse and time travel. Attempts … Read more
IN BRIEF Holographic principle: central concept in theoretical physics. Proposes that the information of a system can be represented on its surface rather than in its volume. Related to the study of black holes and their event horizon. Indicates a relationship between gravity and quantum. Proposes that our universe could be similar to a hologram. … Read more
IN BRIEF Definition: Celestial objects in an intense gravitational field. Formation: Collapse of a massive star at the end of its life. Singularity: Central point where mass is concentrated. Dark matter and dark energy: Mysteries related to their presence around black holes. General relativity: Theoretical framework to study the properties of black holes. X-ray telescopes: … Read more
IN BRIEF Big Bang: cosmic event marking the origin of the Universe according to the current cosmological model. Origins of the Universe: study of the conditions preceding and following the Big Bang. Formation Eras: the Universe evolved through the radiation era, followed by the matter era. String Theory: suggests that the Big Bang could be … Read more
