TL;DR: OpenRelativity as discussed by the authors is an open-source toolkit to simulate effects of special relativity within the popular Unity game engine, intended for game developers, educators, and anyone interested in physics.
Abstract: We present OpenRelativity, an open-source toolkit to simulate effects of special relativity within the popular Unity game engine. Intended for game developers, educators, and anyone interested in physics, OpenRelativity can help people create, test, and share experiments to explore the effects of special relativity. We describe the underlying physics and some of the implementation details of this toolset with the hope that engaging games and interactive relativistic “laboratory” experiments might be implemented.

TL;DR: In this paper, the special relativity can be viewed as the physics in an inverse Wick rotation of 4d Euclid space, which is at almost equal footing with the 4d Riemann/Lobachevski space.
Abstract: Since the special relativity can be viewed as the physics in an inverse Wick rotation of 4-d Euclid space, which is at almost equal footing with the 4-d Riemann/Lobachevski space, there should be important physics in the inverse Wick rotation of 4-d Riemann/Lobachevski space. Thus, there are three kinds of special relativity in de Sitter/Minkowski/anti-de Sitter space at almost equal footing, respectively. There is an instanton tunnelling scenario in the Riemann-de Sitter case that may explain why $\La$ be positive and link with the multiverse.

TL;DR: In this article, the case of a cylindrically symmetric cluster of particles moving in circles perpendicular to the axis of symmetry is discussed on the basis of the equations of general relativity.
Abstract: The case of a cylindrically symmetric cluster of particles moving in circles perpendicular to the axis of symmetry is discussed on the basis of the equations of general relativity. A number of special solutions are obtained, and two interesting results on the relation between the gravitational mass and the sum of the free particle masses for these clusters are deduced.

TL;DR: A long history of attempts to reduce an apparently complex reality to a few elementary building blocks from which everything else is constructed has been made to reduce the complexity of the world as mentioned in this paper.
Abstract: Ever since antiquity, attempts have been made to reduce an apparently complex reality to a few elementary building blocks from which everything else is constructed. This project – now called reductionism – has a long history of failures. One example is the 200-year-long attempt to describe all physical processes in terms of mechanics, such as James Clerk Maxwell's mechanical models of the electromagnetic field. Another is Hermann Weyl's failed attempt to unify electromagnetism and gravity in a single theory shortly after Einstein had introduced special relativity.
