Izvleček
Galaksije so osnovni gradnik vidnega vesolja. Dinamiko teles, ki tvorijo galaksijo, usmerja gravitacijska
interakcija med njimi. Gravitacija je s fizikalnega in matematičnega stališča dobro poznana, a enormno
število teles v galaksiji vseeno povzroča težave. Vsako telo z gravitacijsko silo vpliva na vsa druga telesa in s tem na njihovo gibanje. Pri sto milijardah zvezd v galaksiji je natančen izračun vseh interakcij in premikov nemogoč tudi z najboljšimi računalniki na svetu. Katere metode se potem uporabljajo, da se simulacije vseeno zanesljivo izvajajo? Ali so tega sposobni že običajni osebni računalniki? Ali lahko sami z računalnikom ustvarimo svojo galaksijo ali celo galaktični trk v tridimenzionalnem prostoru?
Kljub pomislekom, da odgovori na zgornja vprašanja presegajo naše trenutne zmožnosti in (srednješolsko) znanje, smo si postavili cilj, napisati računalniški program, kjer bi gibanje množice teles usmerjala gravitacijska interakcija med njimi.
Abstract
Gravitational Interaction of a Mass of Bodies
Galaxies are primary components of the structure of observable universe. The dynamics between the bodies forming a galaxy depends on their gravitational interactions. Although gravitation has been well defined by physics and mathematics, the enormous number of galactic bodies continues to cause problems. Each body having a gravitational pull affects all other bodies, thus influencing their movements. With a hundred billion stars in a galaxy, a precise calculation of all interactions and movements is impossible even when using the best computers in the world. With this in mind, which methods can therefore be used to carry out reliable simulations? Can our personal computers do that?
Can we use our computer to create our own galaxy or even a galactic collision in three-dimensional space? Despite any doubts that the answers to these questions might go beyond our current capabilities and (high school) knowledge, our goal was to write a computer program where the movements of a mass of bodies would be influenced by their gravitational interactions.
