I tried using the code "Gravity Fun at TestTubeGames.com: [ForceGr: r^-3], [x0: -125,y0: 0,vx: 0,vy: 0,t0: 0,who: 2,m: 1000,c: 2]" and got r^-3.png using "Gravity Fun at TestTubeGames.com: [ForceGr: (r^-3)], [x0: -125,y0: 0,vx: 0,vy: 0,t0: 0,who: 2,m: 1000,c: 2]" I got (r^-3).png...

I was using the simulator and found that when I put in r^-3 it did not produce stable orbits while when I put in (r^-3) it produced stable orbits even though r^-3 should be the same as (r^-3) as both are ways to express the inverse cube law. I was just wondering why is it that typing in r^-3 and (r^...

I wonder what kind of orbits (r^(-3))*(e^(-r)) would produce as that would multiply an inverse law by an exponential law.

I tried simulating planetary orbits using exponential laws such as, e^(-r), and e^(-3r), and 2^(-r) and found that they produce stable orbits in the form of flower shaped orbits. I think it's interesting that the exponential laws produce stable orbits while most of the inverse laws don't produce sta...

One of the things I also tried doing with negative mass is I tried using a negative mass planet to accelerate a positive mass planet out of orbit before deleting the negative mass planet and using another star to capture the planet. I found that in order to get the moving planet to orbit a star afte...

Happy Birthday to your friend robly18 Is your friend a member of this forum?

Also I was just thinking about how the gravity simulator only simulates Gravity and not electromagnetism. Could you make it so that we can give planets and stars an electrical charge and magnetic field in the gravity simulator?

I wish I had seen this on TAU DAY I didn't even think about June 28 being Tau Day until you mentioned it in this post.

According to Super Symmetry for every particle with half integer spin there is a partner with integer spin and for every particle with integer spin there is a partner with half integer spin. The supersymmetric partners of the quarks would be the squarks. Quarks are always found in groups of either t...

I was just thinking that Gravitational Waves would also be a good addition to the simulation.
