General relativity is a theory that has been reported more frequently in the media in recent years due to discoveries in astrophysics and cosmology, such as the detection of gravitational waves and images of black holes. However, this theory is scarcely taught in primary and secondary education despite its validity and applicability in various areas. This work aims to analyze the incorporation of general relativity in these educational levels. Thus, the PRISMA protocol is applied in a systematic review of scientific articles between 2012 and 2022, provided by databases such as Web of Science, Scopus, and Dialnet. Research articles in Spanish, English, and Portuguese were selected to account for pedagogical interventions addressing concepts and applications of general relativity for the training of primary and secondary education students. Forty-three studies were analyzed in which qualitative and quantitative treatments of this theory are carried out, and the teaching of concepts such as curved space-time, black holes, and gravitational waves are highlighted. The analysis led us to conclude that there is a preference for a qualitative treatment of the concepts of general relativity. Besides, various didactic resources are identified for its teaching in primary and secondary education. Finally, updating science curricula is emphasized by introducing general relativity to achieve holistic and contextualized learning. [ABSTRACT FROM AUTHOR]

The article discusses the possibility of breaking Penrose's weak cosmic censorship conjecture in black hole collisions in higher dimensions using the technique called large D. It is stated that in black hole collisions with sufficient angular momentum, the resulting black hole is unstable and can split into two, creating a divergent curvature throat. The relationship between physics at different scales in a physical system is also mentioned, as well as the need to quantize theories to understand physics at the microscopic scale. Additionally, the need for a quantum theory of gravity to make predictions at increasingly higher energies is mentioned. [Extracted from the article]

The article reports on the discovery of a precursor to a supermassive black hole in the early universe. The team of astronomers, including Luis Colina Robledo, discovered GNz7q, the first rapidly growing black hole detected in the early universe. Additionally, a study on the creation of a wide-range thermometer using chromium-doped gallium oxide nanowires is mentioned. The article also presents two main topics: the precise measurement of the mass of the W boson and the construction of covalent 2D-2D heterostructures using materials such as MoS2 and graphene. Furthermore, the article mentions the LISA mission of the European Space Agency, which aims to detect gravitational waves produced during the early moments of the Big Bang. The first article deals with the detection of gravitational waves associated with a phase transition during the Big Bang, and the second article discusses the classification of attractor basins in multi-stable dynamic systems using the concept of basin entropy. The third article presents a simple experiment to study nonlinear oscillators using a nonlinear RLC circuit. [Extracted from the article]

The objective of this work is to present a non-technical introduction to black hole physics. The main properties of the four types of black hole allowed by the no-hair theorem are discussed, and some properties of spacetime around a black hole are geometrically examined using embedding diagrams.

The article focuses on laser cooling of positronium, a matter-antimatter system composed of an electron and a positron. Experiments have been conducted suggesting that by applying a laser tuned to 243 nm, the number of atoms in the ground state of positronium can be increased, reducing the temperature of the generated clouds. This could allow for the precise measurement of the electron-positron mass ratio and testing the principle of equivalence. Additionally, the update of the image of the first black hole is mentioned, showing a change in the bright ring around it. Finally, the article addresses the Earth's rotation imbalance due to climate change. [Extracted from the article]

The international team that developed the MIRI instrument for the James Webb Space Telescope (JWST) has been awarded the prestigious group achievement prize by the Royal Astronomical Society (RAS). MIRI, designed and built by an international consortium, is one of the four instruments on the JWST and is the only one that covers the mid-infrared spectral range. Spanish participation in the development of MIRI has been significant, with collaboration between the Spanish National Research Council (CSIC) and the National Institute of Aerospace Technology (INTA). The MIRI scientific team is leading studies on the first galaxies in the Universe, exoplanets and protoplanetary disks, and nuclear regions and black holes in nearby galaxies.

The scientific magazine "Investigación y Ciencia" has stopped publishing due to economic problems. Founded in 1976, it has been one of the main scientific dissemination magazines in Spanish, with an audience of 125,000 readers. Additionally, a study has been published suggesting that black holes could be responsible for dark energy in the universe. It has also been demonstrated that light has a dual nature, behaving as both a wave and a particle, and interference in the temporal domain of light has been achieved. A recent study has shown that temporal slits can produce a greater number of oscillations or interferences than predicted in theory, which has applications in spectral wave synthesis and signal processing.

The article titled "Science and 'relative chance'" is a review of a book coordinated by Inés Pellón and Quintín Garrido. The book, titled "Science and 'relative chance'", is a tribute to Albert Einstein and Niels Bohr on the centenary of their Nobel Prizes in Physics in 1921 and 1922, respectively. The book contains a series of scientific articles written by 19 women and is available online for free. The book explores the relationship between chance and relativity in physics and addresses the sociocultural perception that masculinity is necessary for success in science. It also highlights the importance of creating a more equal and diverse physics culture. The book includes sections on topics such as the acceleration of the universe, black holes, gravitational waves, and quantum cosmology, among others. Additionally, the importance of allies in the fight for gender equality in physics is mentioned. [Extracted from the article]

Computer simulations are enabling researchers to investigate systems which are extremely difficult to handle analytically. In the particular case of General Relativity, numerical models have proved extremely valuable for investigations of strong and dynamical gravitational fields. In this paper we develop the simulation of a Schwarzschild's black hole using the Cactus software, and considering a particular and compatible selection of the following key components: evolution formalism, gauge, initial and boundary conditions and numerical algorithms; furthermore, we validate the numerical results generated by the simulation with some of the analytical results known for this physical system.

The dynamics of the geodesic motion of test particles around arbitrarily deformed static source is studied by using the Erez-Rosen's solution to the Einstein. In order to caracterize the orbits, the method of sections of Poincaré and the exponents of Lyapunov (using the procedure of Bennetin[1]) is used. It is found that when the source possesses oblate deformation the orbits are always regular. On the other hand, for certain cases of prolate deformation there are regions of regular motion separated from the regions of chaotic ones, and in other cases there exists regions where only the two types of motion co-exist; the last ones are reported first time here for this system.
