Anyways another question on GR if anyone can help
...
Pull me up if something I state is a misunderstanding on my part..
1 GR is a field theory
2 GR is geometry that gives us a 4d grid which we call space time
3 GR says that it is the distortions of the grid that gives us what we call gravity
4 GR allows us to determine the path objects must take through space
5 GR offers no physical mechanism to explain its determinations but dictates how matter will behave
6 GR is only used to observe large scale structures ..say galaxy relationships rather than stuff within our solar system.
7 When planning a course for space craft NASA would use Newtonian Physics and not GR???
Yes or No will be a big help so I can consolidate my understanding to date.
