##### Flat Earth Theory / 3 Body Analytical Analyses
« on: May 11, 2020, 06:53:41 PM »
A fairly recent published scientific article is provided below, which analyzes possible bounded orbits using Newtonian central force in the case of 3 bodies.

The analysis demonstrates evidence that:

1. Closed bounded orbits arise from central force considerations

2. The bounded orbits identified have also been verified using numerical computations (see references therein)

3. There is a demonstrably mathematical distinction between analytical solutions, the application in numerical methods, and the application to chaotic dynamics.

##### Flat Earth Theory / 3 Body Solution Simulations
« on: May 09, 2020, 09:49:38 PM »
I ran across a cute Java script from a student at Monash Center for Astrophysics, that plots the numerical solutions of the differential equations that describe central force from gravity on three bodies. Enjoy!

The solutions are found using the well-established Runge-Kutta method in mathematics. For details, see:

##### Flat Earth Theory / Measurements of Newtonian Gravity
« on: May 06, 2020, 04:30:52 AM »
For your purview, see the following review article on recent sophisticated measurements of Newton’s gravitational constant. A wide range of instrumentation is compiled, from torsion balances to atom interferometers.

Such evidence shows excellent accord with Newtonian gravity as a model and observational data.

##### Flat Earth Community / Rocket Propulsion
« on: April 28, 2020, 09:02:03 PM »
A previous post regarding space travel diverged into a discussion on rocket propulsion. In an effort to gather the conversation, I’m starting a new topic on it.

Below show some links which summarize the current theory on rocket propulsion, namely how thrust is obtained as a consequence of CONSERVATION OF MOMENTUM.

The analysis follows directly from first principles, and stands as a  rebuttal against the claim that this propulsion cannot occur in a vacuum.

I’d like to note that a discourse on thermodynamics is irrelevant here, as this analysis holds for ANY type of rocket system - whether it burns a fuel or some other mechanism.

This analysis could easily extend to solar sail systems.
