What are the problems in Newton's law of universal gravitation? Please explain using simple physics if possible.
vissarion.eu said:What is wrong with explanation that small particles bombarding Earth, Sun and Moon from all directions and from directions which they can't bombard (space between Earth and sun) apears smaller pressure than from those side from which they can bombard? Feynman was saying it's wrong because soon Earth or whatever planet should soon stop, but if those particles fast enough and enough small (like atom size) then really not nessasary some over explanation than that which was assumed by old civilisation which meaned Feynman. At least this theory which mentioned feynman shouldn't be such easy pushed away and at least mentioned in physical books in high school or 5-10 classes. How they can hide such things anyway?
ZapperZ said:Because it is quackery.
Would you prefer we teach everything that hasn't shown to be valid in high school classes? Do you know how quickly we have to keep changing those books once we figure out they don't work? Do you know how many of such theories have been shown to be FALSE?
This "shadow" gravity effect has been discussed before, and it is off-topic to this thread. If you think there is a valid formalism for such a model, please use the IR forum, not here.

Newton's law of gravitation was developed by Sir Isaac Newton in 1687. He was inspired by the fall of an apple from a tree, which led him to think about the force of gravity and how it affects objects in motion.
The formula for Newton's law of gravitation is F = G * (m1 * m2) / r2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.
According to Newton's law of gravitation, every object in the universe exerts a force of attraction on every other object. This force is directly proportional to the masses of the objects and inversely proportional to the square of the distance between them. This explains the motion of planets around the sun, as the force of gravity between them keeps them in orbit.
Yes, Newton's law of gravitation is still relevant and widely used today. It is the basis for understanding the motion of objects in our solar system and has been confirmed by numerous experiments and observations.
Yes, Newton's law of gravitation can be applied to objects on Earth, as it explains the force of gravity acting between any two objects with mass. However, for objects on Earth, the gravitational force is often dominated by other forces, such as friction and air resistance, making it less noticeable compared to the force of gravity between celestial bodies.
