So /sci/ is it true that basically the Earth revolving around the sun is not "really" true and its all in your perspective and the context?

No I'm just saying that 'obrit' is a far more accurate word than 'revolves around'. I actually wasn't contributing to the thread in any productive manner so I'll try to now.
I think the argument that the earth orbits the sun is merely a matter or perspective is that in math you can take a coordinate system and map it into a completely different coordinate system in order to make the math easier to do (i.e polar, spherical or rectangular coordinates). In the case of the sun/earth system you can map the equations into a coordinate system where the earth is the center of the sun's movement through space. You'd still be able to use this system to accurately describe the physical universe, determine where a rocket will end up with a certain initial velocity, etc. but the math would be a hundred times simpler in the traditional coordinate system. Although I haven't the foggiest memory of how to do any of this or I'd try coming up with a simple system as an example.
