In essence this mathematical simulation of the Solar System is a form of the N-body problem. The symbol N represents the number of bodies, which can grow quite large if one includes the Sun, 8 planets, dozens of moons, and countless planetoids, comets and so forth. However the influence of the Sun on any other body is so large, and the ...
A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. [1] [2] [3] The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's ...
French philosopher and mathematician René Descartes was the first to propose a model for the origin of the Solar System in his book The World, written from 1629 to 1633.. In his view, the universe was filled with vortices of swirling particles, and both the Sun and planets had condensed from a large vortex that had contracted, which he thought could explain the circular motion of the plane
Estimated to be five billion years old, the Adro Diamond orbits a white dwarf star called Adro (with its name derived from the star it orbits), and possesses a machine-perfect smooth surface and is composed of densely packed carbon, making it almost transparent. Seemingly abandoned, the species that built the structure has long been extinct.
The physical universe is defined as all of space and time [a] (collectively referred to as spacetime) and their contents. [10] Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space.
New research is providing insight into how planets form around these small stars, called very low mass stars (VLMS), showing how the chemistry in the planet-forming disks of gas and dust ...
Giant planets can significantly influence terrestrial planet formation. The presence of giants tends to increase eccentricities and inclinations (see Kozai mechanism) of planetesimals and embryos in the terrestrial planet region (inside 4 AU in the Solar System). [62] [66] If giant planets form too early, they can slow or prevent inner planet ...
