I've always thought about gravity as a pulling force but perhaps it isn't. Is there anything fundamentally wrong with thinking about gravity as a pushing force attenuated by matter?
Are you referring to what Michio Kaku said in the TV documentary on Einstein?jkg0 said:I've always thought about gravity as a pulling force but perhaps it isn't. Is there anything fundamentally wrong with thinking about gravity as a pushing force attenuated by matter?

Believe it or not, he said that gravity doesn't pull you. The relativistic explanation of gravity is that it pushes you. Here is a link to the documentary, now available from youtube:dauto said:What was his comment?

That is an even worse analogy. Discussed many time here.Jano L. said:There is this curved 2D surface which pushes the marble to make it move in circles.
One can do much better without using mathematics:Jano L. said:This is probably close to where one can go without using mathematics...
Gravity as a pushing force is the idea that gravity is not a pulling force, but rather a force that pushes objects together. This concept challenges the traditional understanding of gravity as a pulling force between objects with mass.
The theory of gravity as a pushing force explains the behavior of objects in space by proposing that the force of gravity is actually a result of the pressure of space pushing objects together. This pressure is caused by the presence of mass in the universe.
Some evidence that supports the idea of gravity as a pushing force includes the observed expansion of the universe, the behavior of galaxies, and the bending of light in the presence of massive objects. Additionally, some alternative theories of gravity, such as modified Newtonian dynamics, also suggest that gravity may be a pushing force.
The concept of gravity as a pushing force differs from traditional ideas about gravity by proposing that gravity is not a fundamental force, but rather an emergent force resulting from the properties of space. It also challenges the traditional understanding of gravity as a pulling force between objects with mass.
If gravity is indeed a pushing force, it could have significant implications for our understanding of the universe, including our understanding of the laws of physics and the behavior of celestial bodies. It could also lead to new theories and models of gravity that could potentially revolutionize our understanding of the universe.
