You're very welcome. Thanks for adding Universe Sandbox to the External Links page. It's really appreciated. I've also added Orbiter to the list of programs similar to Universe Sandbox on my FAQ page: http://universesandbox.com/faq/ Agreed. That's what I'm doing the rest of this year (and the...

Good question. The sales of Universe Sandbox are my only source of income as developing Universe Sandbox is my full time job. It wouldn't be anywhere near as polished or easy to use had I not been able to justify leaving my previous job to work on this full time. The free version is a viewer...

I'm the developer of Universe Sandbox. Thanks for the kind words OrbiterSpore. As I continue to release new updates to Universe Sandbox this year, your comments will become even more true. :) I'm now following this thread so please let me know if you have any questions or ideas.

I've made huge changes to Universe Sandbox since my posts in the old thread and I'm now developing Universe Sandbox full time. Universe Sandbox 2 is more powerful, more accurate, and easier to use than the original version. You can now make your own realistic solar system with just a few...

I just posted a 75 second video that shows Universe Sandbox in action. View the video now... http://universesandbox.com/ I also moved the hosting of the software (not the website) to Amazon's Simple Storage Service. This should make installs and updates much faster.

That's a cool idea. The basic concept of simulating gravity is the same in both programs (although I believe Orbiter's algorithm for handling changes in the time step is more advanced). Unfortunately I doubt that there would be much opportunity for code sharing between the projects. I would...

A new version of Universe Sandbox with galaxy collisions is now available: Download it now... http://universesandbox.com/ If you've already installed it, just run it again to update. The latest version of Universe Sandbox has a number of new features and improvements including: Visualize...

James, I'd be interested in checking out this Time article and trying to more accurately set up the situation it describes. Is the article online? And you're right... Pluto and Charon totally orbit each other (and you can see this in Universe Sandbox, load the system: Pluto & Moons. The code...

Universe Sandbox isn't done and my ideas for new features are never ending... :) As I said in my earlier post I'm working on representing galaxies to scale and showing the nearest 1000 stars to our Sun. Future improvements will address the graphics (adding light emitting from stars) and the...

Thanks to everyone for checking out my program. I'm the developer of Universe Sandbox. ______________ I appologize to Scrooge McDuck for the slow installation. I trust that it did eventually work. I'm investigating moving to a different hosting provider which may help this problem...
