Science and Astronomy Questions

13682 Does anyone know any accurate 2d simulations of convective cloud systems that can be run on the average PC? Something like this that doesn't use 100 million particles.  I don't think it is possible to get accurate simulations of convective systems, especially tropical cyclones, in 2D.  These ...

Unrealistic stars.

13945 Actually, now that I compare it to the Milky Way, it seems that I can't spot any stars at that distance. They don't even show up. Seems like that was just a galaxy of incredibly massive stars. Is that scientifically accurate? Age could explain size but not mass. I don't think so. Massive star...

12707 What's the type of fluid flow in Jupiter's atmosphere that creates these clouds formations? I think it's just called turbulent flow, which is what leads to the vortices and mixing.  The other type of flow is "laminar" , where the fluid flows in smooth sheets without breaking up into...

What's the type of fluid flow in Jupiter's atmosphere that creates these clouds formations? The same process looks similar to Earth as well.

11868 1. Knowing the Moon gradually recedes from Earth as the planet's rotation slows down thanks to the mutual tidal interactions; does the rate the moon recedes get slower as Earth's rotation get slower? You are totally right. 4.5 billion years ago the Moon was born at just 3.8 earth-radii of dis...

11720 Not even comparable to the scientific realism of Space Engine in fact. I can't agree with you. Have you found a Herbig Ae/Be star in SE? I never did.  But there are lots of them in Elite Dangerous.  Yes, ED is a game, but it's done well as a video game. Yet SE is a space sim game engine, so i...

I am in the process of making an album (maybe 10 songs in total) based around this game. So far I have 3 songs.  https://soundcloud.com/octavermusic The soundtrack of the game is great and I am having a fun time making tracks to capture the feeling of wonder and awe of the game.  Also if the sample...
