But the Sun is tiny compared to the solar system which is tiny compared to the distance to the next star. Oh, did we mention that there are over 100 billion stars in our galaxy (which is about 100,000 light years in diameter) which is one of hundreds of billions of galaxies in just the observable universe (which might be infinite for all we know). Don't feel small. We find it liberating. Your everyday human stresses are nothing compared to this enormity that we are a part of. Enjoy the fact that we get to be part of this vastness! About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

How come the suns are always close to the center of the axis?

Dude, Thank you. This is great! I remember having a 2D version of this on my mac classic and wasting lots for time runnings sims and dreaming of a 3d version. Now I just want to know how to save a sim as an .mp4 (or whatever movie format) and play it back on my TV, ya' know for geeky party goodness :-) Thanks again.

I still cant figure out how to break down a mobius strip into a mathematical equation, yet we use it everyday in all kinds of stuff. I wanted to know if it can pass between itself, while holding its shape or is it fixed.
-
Love it! I just wrote a paper on black holes, so it's funny that this should come up. Great sim
-
Thanks everyone for the comments and suggestions. @CustomPcTech - if you follow the link to the simulation, the source code is in the box to the left, just scroll down past the introduction.

I also wonder if dark matter has anything to do with the formation of accretion disks?
-
I wonder if you can go back in time, and get the dust cloud from a solar system?
-
If the initial conditions are the same for different simulations, same results?= determinism?
-
can we see the source code for the program?
-
Great work Peter, I was hoping someone could pull all these ideas together.
-
Yeah, that's the coolest thing published on youtube today!

imagining the 10th dimension rob bryanton...

Well after playing with this simulation a little bit I found out that the higher your gravitation constant is, the faster the universe expends (max distance gets higher and higher) provided you have a starting rotation speed that is higher than 0. so if the calculus algorithms are correct ( and I didn't see any obvious error :D) that could be rather interesting to investigate ^^ Maybe a proof of concept of the Big Bang theory hummmmmm.
-
Very cool, I know where I'll be for days now.
-
I've played with and it get's more galaxy looking if you reduce the initial mass range, reduce the initial spin, increase the initial mass distance and double the number of particles so the system has more time to evolve. Of course it's not very practical because it may take hours.

fantastic! I love little simulations like this
