Thanks for the interest fellow travellers
Steve mentioned......"Now, the holy grail of physics is the unification of Gravity, Weak, Strong Nuclear Force and the Electromagnetic Force."
Steve I think about this all the time... and if you take this in confidence and dont spread it around I can tell you that the push gravity approach that I have subscribed to certainly has the opportunity to do this....
At one stage Hawking said he received at least one paper a day claiming the grail was contained therein

It is important to understand that in GR space and time do not have an independant existance. It is the "spacetime" that is warped by the presence of matter/energy as per the Einstein equation.
Yes I understand this...... a pythagoras therom with a "fourth" ..side or arm... time....which time "changes" as space bends from an influence of local mass...
What I do not grasp is why mass needs to seek a "straight" path which is in point a line of the least resistence (of space) conecting to the most local "bent" space.... or what is it that tells the Sun to follow its "straight" line to where ever it seems to be headed...
I see a space/time grid as geometry that seeks to describe "space" in a way we can measure and relate our presence within it (space)....why that grid dictates that a section of the grid describing space say near the Sun becomes "small" and as such masses in a part of the grid with bigger squares (less space curve) are bound to move..in a straight line..to the point where space is bent more...is the aspect I miss...what dictates this within the grid or the math??? I get to a point where I can see a grid much like a weather map showing highs and lows (of gravity or intensity of space curvature) but can see no rule that says the high must move to the lower pressure areas....
Dont worry about trying to field my concern I am reasonably happy with all that I can understand of the way current science approaches the matter..
Thanks for all the neat information....
