<div id="RTEContent"><blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">If you're into physical particle systems, Cyrille & Damien Henry have a<br>mass/spring plugin, which was called PMPD when I saw their performance. <br>Else, GridFlow could do things like that too, but it can also do density<br>models, which are more like "we have the space and then there's matter in<br>it" whereas particle systems are more like "we have matter and then it's<br>somewhere in space".<br></blockquote>PMPD would be a good tool for exploring gravity - but you would have to explore the escape velocity scenario, where links (springs) are broken if an object attains a certain angular momentum, and a different (repulsive) mechanism comes into effect (and what about dark matter/energy or as it should be termed, the foo fudge factor (FooFF)).<br> <br> Also - how fast is your computer? They normally use supercomputers to do this, I
think you may have problems on a standard machine. Modelling aspects of the universe such as doppler shift would be easy, but it's a problem of scale...perhaps you ahould start with a solar system?<br> <br> Best,<br> Ed<br> <br></div><BR><BR>-><br>-><br>--><br>---><br>-----><br>--------><br>-------------> r3search + praktik EK5perimenz<p>
