WebTo convert from redshift z to velocity v measured in kilometers per second, the formula is v = c z, where c is the speed of light, c = 300,000 km/sec. Thus, in this example, galaxy 587731512071880746 appears to be moving away from us at about 30,000 km/sec. This value is typical of the galaxy redshifts found in the SkyServer database. WebYour issue is with the particles. The position of each particle is calculated based on its position in the previous frame. When you send the scene to render, it opens a copy of your scene in the background and begins rendering at the specified frame, it doesn't pre-cache frames 0-116 like you would in the viewport.
