Planets in gravitational well

Planets in gravitational well

Far in space, gravitational force coming from one direction is almost cancelled by gravitational force coming in opposite direction. An object in that position continues in strait line because the net force on it is zero.

Because of all its atoms, the sun blocks some of that gravitational force around itself. An object located in that space is pushed towards the sun because gravitational force coming from direction opposite to the sun is bigger now.

Gravity from space is blocked partially by the sun; gravity density is lower close to the sun and increases according to 1/distance squared.

But the sun itself is also an emitter of gravity. That means close to the sun gravitational force is bigger that in space around. That extends to a certain distance from the sun.

At a certain distance, the density of gravitational force from one side is almost equal to the density of gravitational force coming from the direction of the sun.

That makes a kind of big sphere where gravitational force is almost equal on each side on a line pointing toward the sun. That region or bubble is the gravitational well . Planets cannot go in strait line because in doing so, they enter a region where the gravitational force from outside is now bigger and they are  pushed back towards the sun. When they approach the sun, the same thing happens in opposite: the gravitational force coming from the sun is now bigger and the planet is pushed away, In that manner, the planet goes around the sun and is a satellite.Untitled 8

Region around the sun emitting in all  direction added to what is emitted from  space  causes a different density region.

 If we add the gravitational force from the sun and from space, we have something similar to that drawing, showing the low density of gravitational force all around the sun.

The graph shows where the planets are in that ‘well‘; they are all situated in the brown rectangle, at a distance between 5.80E+07 m and 6.00E+09 m.

 In order to show the gravity well,  we must use the log value of the distances. The blue line is for the gravity from space that was partially blocked by the sun and the  red line is the gravity emitted by the sun. It goes to almost zero at far distance.

In this graph, the sun center is at 0 on x-axis.

The mass and the speed of the planet will permit to find an equilibrium point and it becomes a satellite to the sun. Small planets are far…

The gravitational force in this graphic represents the net total force when we add opposite forces. Depending on its speed, the planet finds the distance away where the force towards the sun equals its centripetal force.

Einstein seem to have a vague idea of that gravity well and tried to explain it with his theory of space time curvature. Space is not curved but its different density will influence objects towards the sun as if it was “curved’ inward.

Following the equation (F = Gmm/dd) there is a possibility to have planets between the sun and Mercury if the speed is big enough. There is no such planet there. This is because of the gravity well described here. A planet closer to the sun would be pushed away by sun radiation of gravity.

This also explains why most comets do not fall into the sun as they should because of the pressure of the gravity emitted by the sun. It will push the comet’s tail away from the sun.

About Louis

In this site, I will give a summary of the discoveries to date and the new one also. My family helps me a lot: Benoît is discussing the findings; my wife Madeleine, a nurse is helping also. My daughter Rosanne devised this WEB site and her husband Jamie is a proficient programmer who can help me a lot, even with his big family of 7 nice kids. I am now retired after 52 years of teaching mostly physics and maths. Bonjour Je suis un professeur de sciences depuis plus de 50 ans. J’ai enseigné de la 7e année à la 12e puis à l’université d’Ottawa et enfin au collèege. J’enseigne depuis plus de 25 ans au collège Boréal, Sudbury, Ontario, Canada. Depuis le début, je désirais comprendre la gravité. Après beaucoup d’essai infructueux, j’ai découvert qu’un rayon de lumière peut bloquer la force de gravité. Encore beaucoup de recherche permettront de comprendre la nature de la gravité. Mon grand gars Benoît ia fait un baccalauréat en Sciences infirmières . Il m’a beaucoup encouragé dans ma recherche. Mon épouse Madeleine est infirmière et ma grande fille Rosanne a réussi à faire ce site WEB malgré le travail avec ses 7 beaux enfants. Mon gendre Jamie Parent est programmeur et très habile avec les ordinateurs. Louis Joseph Rancourt
