Another assumption which is widely used is that the Force of gravity is always directed towards the source of gravity...
The magnitude of force depends on the mass and the position of the object from the source of gravity. However it also assumes that force remains a vector of fixed direction....
In other words the "direction" of gravitational force doesnt depend on mass or position... which is totally wrong... infact with distance the direction should become less certain...
There is a simple principle behind it... as any wave moves in infinite space it looses its directional sense...(throw a pebble in water and after a sufficient distance it becomes difficult to define the source of origin..as the curve tends to become a straight line...just like the curve we see on the earth)
Therefore not only the magnitude of gravity depends on mass and position but also direction of gravity...
This fact is not considered in the gravitational wave theory...
GR again fails to predict the wave nature of gravity.

The experiments proved nothing new.
Infact with every experiment they prove that space time is flat becuase they use the coordinates of flat time space.
The GR equation is solved with reference to some standard solutions which may or may not be true...
And the results are only approximate..
Several other theories have been running parallely to explain those experiments.. most notable among them is Whitehead's theory of gravity.
It will stupid to look experimental coorelations when the degree of uncertainity involved is very high. The experiments only support a model or theory.. A theory never gets proved.
Therefore experimental discussion will only spoil the necessary skeptism required to discuss such matters.
Again when we look at the theory we see that there is no force in the GR because all frames are inertial...
Any gravitational force which we see is due to change in the curvature of space time.
Einstein was mad. And that is the general public opinion.
Where is the curved space time ?

One more thing , the equations are made to behave grvaitationally by using a constant which reduces it to Newton's gravity at lower speeds.
The assumptions of GR doesnt inherently lead to gravity.

GR is a postulate based on no simpler postulates than its 20 page equations.
We experience force everyday ... dont we ? Try to Jump on the floor and it will become obvious that curvature of space time doesnt propel you into an effortless trajectory... Obviously you are jumping against the inertial destiny of matter surrounding you.
The water in the dam falls under the force of gravity...
And the theory claims that there is no force. It claims that forces vanish when consider the space time as curved... !!
If such a space time exists then it exists only in mathematics and not in real world.
Actually any straight line coordinates can be transformed into curvilinear coordiantes but does that change the knowledge of properties contained in the coordinate system..? No.
The chain of causuality remains entact... the magnitudes and directions of the properties might change...but not the cause and effect..
Similarly by transforming the flat time space into curved time space doesnt and shouldnt make the force vanish otherwise the causuality gets violated.. If a water from the dam fall then it is bound to produce a force to move the turbine.. without force the turbine can not move...
In other words GR claims that turbine never moves in curved space time becuase the gravitational force is absent in the curved space time.
Whitehead's theory explains all the experimental observations...except few , however the theory is not dead as the proponents of the GR make us believe.
What I am criticizing here is not just GR but the general approach towards relativity type solutions including quantum gravity...
Curved space time can never replace the real physics because that is what matters.. Curved space time is an illusion created to serve mathematicians not physicists.
Curved space time is not a real coordinate system....
Reimann theorem states that only real coordinates can coorespond to real space and time..(rods and watches)
Curved space times is only the parametric representation of flat space time... the curvature is related by the metric of curved space time.
The metric can exist in any form ... and therefore it is used to adjust to the observed gravity...
Had there been no observation of grvaitational field then we wouldnt have asked the question... !!
The theory still fails to answer why this metric only ?
In other words why gravity ?
Why not something else ?
(What is force ? Force is equal to mass X acceleration.. or you can understand it as resistance to any change)

The curvature of space time accounts for the gravity and not the change in curvature.
However it is obvious that the the curvature changes as we move forward in time...
GR doesnt claim to know all the time contained in the universe history... it only suggests possible scenarios depending upon the mass density and cosmological constant.. It doesnt rule out scalar fields..

Just to complete the discussion.
The GR transforms away the gravity by using curved space time.
The transformation is only mathematical because we know that Gravitational bodies exists for real.And without mass the transformation wouldnt have existed.
I mentioned Whitehead to illustrate a simple fact that it is always possible to construct a different differential equation of which Schwarzchild's equation is the solution. Whitehead need not be true.
