Force of gravity shown here.

https://www.youtube.com/shorts/X0H9pqXe2hc?feature=share ...it shows that gravity is composed of two perpendicular forces one opposes to the other in a straight line of diferent values of forces. The line of the force moving forward, is of Kinetical in value, it is always straight, gravity is not there. When an object passes by another object of greater size if it makes a circle, it attracts it but the atraction of the biggest one is stronger, if the direction of the other object is of a straight line in respect to the largest object, and it goes in a straight line, it does not. So, if the circle turns too elliptical in such a way that most of its curved lines straighten to start descripting more of a straight line than an arc one in the ellipse, it excerts less atraction, if it stops, it pulls in the object,inward. If the object keeps turning around the larger object, the largest one pushes it inward ending by smashing its center, if there is any gas around the bigger object, the gas acts as part of the big object on which the smaller one smashes to it; in that situation the bicyclist smashes onto it. Here the cyclist goes in a spiral crazy end. but in our sample, after the cyclist goes too close to some part of the curve, he turns the bicycle to the opposite direction and the force acts in the opposite direction, keeping the bicycle always turning around and not losing its balance; if the circle were bigger, the bicyclist would make a much more less arc of the line describing the arc of the ellipse. If the bigger object were too big, the smaller object would have to compensate by moving further or increasing its pulling attracting force at a further distance in order not to fall onto the larger object. Gravity always has an opposite force: opposite force of gravity that makes a straight opposite line (both forces) of which one of the lines is less strong than the one direction toward de center o the biggest object. That is the case in which any small object moving around a larger one will hit that larger mass or smash it. Cuz the forward speed of an object moving past a larger one contains a weaker and backward pull. Here SpaceTime goes at work, it takes billions and billions of years for the smaller hits the bigger one. To be known: the solar system was bigger, now it is much closer but cuz a special force, solar system are moving one away from others, same does galaxies, yet withing them, they comprise by themselves and move away amongst all, independently.
