### Re: (r^-3)/(cos(r)+rsin(r))

The way I built those systems was by flinging planets at distances and velocities I thought were most likely to be stable a bunch of times until I would finally get ones that would orbit the star. Most would either be repelled by the star at some distances causing them to fly off into space or reach...

Much closer than the ...

### (r^-3)/(cos(r)+rsin(r))

I found that it is not only possible to get stable orbits using this law for gravity but also to get solar systems of multiple planets. Screen Shot 2017-03-07 at 10.12.27 PM.png This solar system has seven planets and after hours of running the simulation only one planet was kicked out of the solar ...

### Re: Suggestions! (new)

In this case the uncertainty principle would be σpσv=ħ/2 with σp being the uncertainty in momentum and σv being the uncertainty in velocity. From the equations p=ma we can get the equation σp=mσa in which σa is the uncertainty in acceleration and m is the mass and from the equation a=mv^2/r we can g...

### Re: Suggestions! (new)

[quote][quote]If and only if the derivative of the distance between two objects (dr/dt) was in exactly the direction same as the distance between the two objects r/[quote] I think this is not correct. The derivative of distance is always in the same direction as the distance itself because distance ...

### Re: Suggestions! (new)

Also the postulates of Galilean Relativity would be changed to: 1. There is an absolute space in which the laws of physics are true. An inertial reference frame is a reference frame that has constant relative acceleration (not velocity) relative to absolute space. The second postulate could stay the...

### Re: Gravity Art Megathread

I was curious to see if planets could have moons assuming a reciprocal law considering that the moon would be more effected by the gravity of the star then the planet it orbits. I found that the answer is actually yes. Screen Shot 2016-02-16 at 12.14.01 AM.png This is a planet orbiting around a star...

3. Altering Newton's Laws. Right off the bat -- seems like it could be hard to define consistently? As in: if an object with no forces on it should accelerate... which way should it go? The third law would be hard to get around without redefining the force of gravity in some non-symmetrical way. I ...

### How to produce other inverse laws in parallel universes

I was just thinking about which gravitational laws a parallel universe could have. I know that having another inverse law with a whole number for the exponent could be produced by a parallel universe having a different number of dimensions. For instance if a universe had two spatial dimensions then ...

### Reletivity seems to revert it to r^-2

I noticed that if I set the force law to r^-1 or r^-3 and then turn on relativity it produces nearly elliptical orbits even though without relativity it's only r^-2 that produces elliptical orbits.
