AshUchiha said:Wow, thanks it helped a lot. So the in the examples shown in the second video, I find Newton's theory more reasonable, as gravity acts on all objects with mass and energy at all times right?.
All objects have mass and energy, so yes.
Just one last question, is gravity a relative quantity??, for example let's assume a very big (such that all other celestial bodies are negligible in mass to that), is on the space. So all the objects would fall to it ?
All of the objects, including the very large one, are attracted towards the barycenter of the system.
As that objects velocity and gravity is much higher compared to those.
The velocity is only relevant for determining the orbital characteristics of the different objects. It has no effect on the strength of gravity.
