Description
The rotation curve of the visible stars and gas in a galaxy can be presented by plotting its orbital velocity. However the galaxy rotation curve obtained by using the relation of Newton’s universal gravitation fails to explain the observed rotation curve. This has led to the dark matter hypothesis. At present there is no direct evidence for the detection of dark matter and the area is still open for an alternative. In this work, we present a computer simulation for the galaxy rotation model. Our simulation can show that the galaxy rotation curve simulated by using the Newtonian relation is incorrect as expected. Instead of pursuing the dark matter hypothesis we introduce a relation of central force between matter based on Mach’s principle. By combining the Newton’s universal gravitation with this relation we will show the corresponding galaxy rotation curve.
