But although they are colliding, the ordinary matter in the constituent galaxies, due to the vast distances between component stars, pass through each other without incident.
By the new model, a variable displacement hydraulic pump is simulated by the ordinary hydraulic component with hydraulic resistance, abrupt pressure change and invariable flow.
