Science and Astronomy Questions

21964 I calculated that I've spent just over a week airborne over the past 12 months covering a distance of about half a light second.  Does this also mean that I've travelled half a second further into the future than if I'd remained at home, or is the maths more complicated? Half a light second (...

Science and Astronomy Questions

Mathlogger did an excelent video recently about this and how is connected to Fourier series. qS4H6PEcCCA At the end of Geocentrism astronomers started to add epicycles on epicycles. This nested structure worked (and works still for the complex orbital perturbations we are able to measure today since...

General suggestions for SpaceEngine

21812 Working Wormholes I know that you are already planning to add this, but It's just a reminder. Has been proposed several times and there is an entire thread for this where it has been discussed. 21812 A Multiverse When you are flying out of the Universe, for example with a spaceship or just in...

Realistic shapes/maps of known Solar asteroids/comets

It looks like people is starting to refine 3D models for asteroid Ryugu (now been visited by Hayabusa2). This model was made by Roman Tkachenko. I've been unable to locate the actual model but I guess we will have the opportunity to see it in SE when a model based on better data arrives. 7-7xg4XAcIk

What exoplanet might reply us back?

21469 I think in about 10-20 years someone will reply back. Look at this table . The closest arrival date for a targeted interstellar message is the Morimoto - Hirabayashi Message, which arrived to its destination, Altair , in 2017. Altair is located just 16.7 light years away. So a response could ...

21445 What are those white curves? Equipotential lines. The generalized "gravitational" force in one line is of the same magnitude in each point of the same white line and the direction of the force is perpendicular to those lines in each point. They are like contour lines in topographic ...

Solar System dynamics discussion thread

21401 Reading this question, I though that the obvious answer is no. Moon should be more attracted to Earth, since it orbits it, instead of the Sun. So I checked the gravitational force calculator. Moon is attracted to Earth with the force of 178 142 946 TN when in apogee and to the Sun by 435 641 ...

21288 He did? Where? Well I said; 21283 I like the historical explanation PropulsionDisk Maybe I didn't emphasized that sufficiently. 21284 So in the 19th century, no telescope in the world could possibly hope to see Uranus be perturbed by Neptune over the course of a few months. That's actually qu...

21266  Specifically, how with Newton's Laws was the location of Neptune pinned down with such accuracy?  I think this is what FFT (and I as well!) are most interested in Indeed this is what I was thinking about. I like the historical explanation PropulsionDisk but to make a more in-depth discussion...

Guys, Is not about Watsisname nor me. You are all welcome to contribute. The great thing of SE's community is that even if we are all ignorants in one way or another, there's a lot of people that embraces the method, wants to learn, is able to make clever self-criticism, search for sources and wants...

How do you think we can get to Proxima b?

This is getting quite off-topic PropulsionDisk. Maybe we should follow the discussion in the Science questions thread since how an electric circuit works is not the main issue to get to Proxima Centauri. Anyways I respond here one last time (let's migrate if you want to keep it going ok?). 21158 But...

How do you think we can get to Proxima b?

21128 On the Wikipedia it says that MMRTGs use the natural decay of plutonium 238 to make ELECTRICITY, electricity is the same as voltage right? So MMRTGs can produce electrons for capacitors. Electricity, by itself, is a broad term that could mean different more specific things. In the case of Wik...

21112 Heh.  I've never thought of timing of light as an explanation of stereo vision.  But it does have a grain of sense in it, indirectly.  We have stereo hearing, and though stereo hearing doesn't primarily work that way, it's should be biologically possible to take the timing into account to hel...
