I really wanted to see the quiet and slow death of our beloved Sun over the eons, but instead it appears to be stuck in an endless loop. ![]() Would it not be prudent to simulate mass loss (which appears at 0 in the dynamic tabs) for a remnant? Only radius and temperature change with age of as stellar remnant. I guess there will be fits and starts as gravity and pressure fight over the dying star, reigniting the fusion at different pressures and temperatures, but there is no different in density or mass of the star beyond this point. The numbers in the cycle always remain the same. Is there not a nebula formed by this expansion? I would've expected a gentle (in stellar/nova terms) expulsion of the outer layers of the sun as gravity loses to temperature/pressure.Īlso after this initial transition into nova remnant the cycle just goes through an infinite loop of cooling and shrinking and then expanding suddenly. The change from Sun to Sun nova remnant is sudden. I thought the Sun would turn into a red giant first, or is this not simulated? This size is not as large as I would have expected (ie: radius of up to 1AU). I have a few questions/comments at this point. The Sun ages and expands with all the side effects that has, but once it reaches a certain size it then instantly turns into a Sun nova remnant. I set the stars to realistic and I'll use the Sun as an example here. I recently opened and ran the Sun lifecycle simulation and have also tried this with other stars in my own simulations. Get ready to witness the unthinkable: 100 Jupiters colliding with the mighty Sun Brace yourselves for. very bright and colorful.This is my first post here, and I must say I'm enjoying playing with US2 quite a bit so far! Were about to unleash cosmic pandemonium in this mind-bending Universe Sandbox 2 simulation. The Rosharan system looks really crowded though and umm. I think they ended up looking really good, so feel free to use them as backgrounds. ![]() You can switch between available devices while the simulation is running. does a quick test on each (and vanilla CPU support) to see what is the fastest and then uses that device. For each system there is a zoomed-in, zoomed-out, and diagonal line up version of the planets, a 90° angle landscape version, and one where each of the planets are placed around the sun at random points along their orbits (though the Taldain System does not have this last one, for obvious reasons). When it starts up it detects all the available OpenCL devices. Space is actually 3°K, not 0°K: Yes, that’s true, the ambient temperature of empty space is around 2.7°K due to the cosmic microwave background. ![]() My goal with all of this was to realistically re-create the starcharts, but I also thought that they could make pretty cool backgrounds, so I made a few different versions with the systems and planets in different orientations, and I've included them all here. You’ll notice that because of these assumptions, the 132 years that we come up with really represents a minimum amount of time it would take for the oceans to freeze solid. Took a very long time to do this and to position everything the right way, but I'm pretty happy with the way they all turned out. I had to get creative about the colors of some of the planets, because the program doesn't actually include a way to change the colors of gas giants, so I had to edit the code of the bodies directly and repeatedly change the RBG values until they looked right. So I was messing around with a universe simulator called Universe Sandbox 2, and I thought 'Why not try to recreate the Cosmere planetary systems?' So I got out my Arcanum Unbounded, and thus began the long and arduous process of trying to make and arrange the celestial bodies of a wonderful fictional dwarf galaxy.
