I chose 2 x 10^23 and 6 x 10^17 for a Sun and Earth system (scaled down mass-wise) and managed this straight away. Think I need to adjust the velocity so that we don't all burn up on closest approach!
Nice demonstration of Kepler's laws too.
Oh joy. I've just added Mars. Shows opposition and all that. This is better than 'sliced bread' !

]]>Good page. I found the animation tricky to use but I think this has great potential. Mostly, new particles either zoomed off or just crashed into the growing central mass. After some practice I managed to get one particle to orbit the central mass. The 'ellipse' had an axis progression (Mercury type orbit?). Have you built in some Einsteinian relativity element or is this just an accuracy issue? Would it be possible to provide greater control of each particle so it's easier to set up orbits? eg create a new particle, then specify its direction of motion, then the magnitude of this motion. That would allow controllable experimentation.
I made the central mass about 10 x 10^25 and the satellite 1 x 10^23. I say 'about' because most of my attempted satellites just crashed into the 'planet'. It took a while before I managed to get this one with the right tangential velocity.

]]>Any ideas on how to best present space-time curvature will be welcome!
That is the standard way to illustrate space-time curvature. Sometimes, you see an animation of two balls (planets) on a sheet.
All in all a nice page.
]]>The page on Gravity is very well made.
The units of 'g' and 'G' in other systems (other than SI), whether they are scalar or vector, and affect on Altitude and Latitude may be included.
The presentation is flawless.
Great work!
]]>Would value your feedback.

Also help in tightening up the wording is welcome, too.
