Question on the Inherent Instability of Lagrangian points

In summary, the conversation discusses the possibility of a second, repulsive force in addition to the known attractive force of gravity, and whether this force could account for dark energy and matter in the universe. However, there have been numerous sensitive tests and observations that have not shown any significant deviations from the current theory of gravity. As personal theories are not allowed on the forum, the thread remains closed.

The question revokes around my personal hypothesis that there is two forces connected with the Gravitational Field one obviously attraction between two bodies that is linear and the second is a less powerful repulsive force that emanates in a spiral motion off of rotating bodies that causes the tendency of object to rotate around larger objects in one general direction (like the planets in the solar system). Has anyone tried to factor out other effects like the gravitational pull of other planets, moons, the force of the solar wind and other known phenomenon to see if there is a definite measurable effect on satellites in the orbit of the Lagrangian points. Obviously two factors would affect the repulsive force; Spin and Mass. The Sun is larger and spins faster then the Earth so the repulsive effect would be larger and the moon doesn’t spin at all except in it’s relation to the earth. If one could find a definable effect, then obviously there would be another as of yet undiscovered force that might account for at least a part of the predicted amounts of dark energy and matter in the universe and lead to a more accurate theory of gravity that would explain the many unexplained anomalies in orbits of objects in the universe. Either way as risky as it might seem, it would make for a great scientific paper.

There have been many, many sensitive gravitational tests, including many from spacecraft and satellites both in orbit and heading out of the solar system. There have been practically no unexplained deviations from standard GR, and the very few that have cropped up have very plausible explanations that leave GR intact. We've also observed plenty of massive objects that are rotating much more rapidly than the Sun. If there were any such effect like you're describing, we would have noticed it.

Since personal theories are against PF policy, this thread shall remain closed.

1. What are Lagrangian points?

Lagrangian points are five special points in a two-body system where the gravitational forces of the two bodies cancel out, allowing a third, smaller object to remain in a stable position relative to the two larger bodies.

2. Why are Lagrangian points inherently unstable?

Lagrangian points are inherently unstable because they rely on a delicate balance of gravitational forces. Any small disturbance or perturbation can cause an object to drift away from its position at the Lagrangian point.

3. What factors contribute to the instability of Lagrangian points?

Several factors contribute to the instability of Lagrangian points, including the varying gravitational forces of the two larger bodies, the influence of other nearby objects, and the effects of solar radiation pressure.

4. How do scientists study the instability of Lagrangian points?

Scientists study the instability of Lagrangian points through mathematical models, computer simulations, and observations of objects in these points. They also use spacecraft missions, such as NASA's James Webb Space Telescope, to gather data and further understand the dynamics of objects in Lagrangian points.

5. Can the instability of Lagrangian points be overcome?

While the instability of Lagrangian points cannot be completely eliminated, scientists are researching ways to mitigate its effects, such as using propulsion systems to maintain the position of objects in these points. This research is crucial for future space missions, including those involving asteroid mining and space exploration.
