Science and Astronomy Questions

I think that could work fairly well, though I might call it a pseduo-3D simulation at that point since you keep track of the flow between layers.

Work progress - 0.9.8.1

14001 Isn't it still better to have objects at the correct position even if the distance is wrong than objects with both incorrect position and distance?  W hen SE creates a procedural star, it "invents" three "random" coordinates. How is that any better than starting with 2 rea...

Belief is to think that something is true because someone told you, or you read it somewhere, or because other people think it is true, and you decide to think that it is true as well. Science teaches us to question a belief.  "Is that conclusion supportable by evidence?"  "Are the pr...

Show off your work

For fun let's do the math.   The Moon is about 362,000km away from Earth, at its closest.  The human eye can resolve details down to about 1 arcminute.  At 362,000km, 1 arcminute is about 105km.  The wall is only about 6m wide at its base -- more than 10,000 times too thin to see from the Moon!  The...

I've removed some of the drama as well; all that needed to be said has been said.  Let's move on and please try to keep the Work Progress thread clean now, thanks. :)

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 ...

Qr Bbpost How can a moon be larger than its parent planet?

Lower density.  But it's perhaps better to call this a binary planet than a planet + moon.

Just so.  For example, on some level we don't know what stars are.  They're just lights in the sky that "behave nicely" in the sense that our knowledge of other phenomena (gravity, thermodynamics, nuclear physics, etc) happen to make sensible, testable models about how they appear and on ...

There shouldn't be any limitation for that.  It's just discouraged to have several posts in a row in the same thread.

13666 If events are not absolute, then doesn't that make time travel to the past possible even with just one timeline? No.  Events are absolute in the sense that one, and only one, event specifies a location in space-time.  (In other words, a particular point of space-time is  that event).  What I ...

Ok A-L-E-X , I'm sorry to do this, but I did give you a strict warning, and after both Doc and I had given several gentle warnings.  4 posts in the same thread in rapid succession is not   acceptable; I'm giving you 4 days off for it.  You must  figure out a way to avoid doing multi-posts. You can r...

Another image.  This time I combined several frames from the GoPro with some close-up shots to get an HDRish wide-angle view.  I love the way the colors turned out. ^_^

DoctorOfSpace , no, I'm telling you that you are right. :)  All events that make up your life from birth to death exist as a world line in space-time.  Your eating something in 10 years is an event which is unambiguously in your future. The point I'm making is that past and future are not always un...

13598 Yes I know what is aerobraking and have done this in Orbiter spaceflight simulator multiple times. I thought it might be different from Mars(or any other terrestrial world with atmosphere) on gas giants since they have fast rotation, which causes large planetary scale storms.  Ah, yes, it sti...
